3
API Versions 31.0–40.0 Deprecated: Retiring in Summer '28. All integrations must be on API version 41.0 or later. Audit your integrations NOW — don't leave this for later.
🤖
Agentforce — The Biggest Theme of Summer '26
Multi-agent orchestration, new builder GA, Agent Script, and more
✅ GA
Multi-Agent Orchestration — Agents Working as a Team
Summer '26 introduces Multi-Agent Orchestration in Agentforce — enabling multiple AI agents to work together as a unified team to solve complex, end-to-end workflows. Previously, agents worked independently. Now they can coordinate, delegate, and collaborate across a workflow.
💡 What This Means
A sales workflow can now have: Agent 1 (prospecting) → finds leads, Agent 2 (qualification) → qualifies them, Agent 3 (scheduling) → books meetings — all working together without human intervention. One seller can operate with a full revenue team behind them.
🔧 How to Enable
Agentforce Studio → Multi-Agent settings. Build individual agents first, then define orchestration rules for how they hand off to each other.
✅ GA
New Agentforce Builder — Default from July 13, 2026
The new Agentforce Builder is now Generally Available and becomes the default starting July 13, 2026. The "New Agent" button will no longer open the legacy builder in Setup. Good news — you can migrate existing legacy agents to the new builder in just a few clicks.
💡 Migration
Agentforce Studio → select your legacy agent → Upgrade to New Builder. All your agent configurations (subagents, actions, system messages, connections) migrate automatically and convert to Agent Script format.
⚠️ Action Required
If you have existing agents built in the legacy builder — test the migration in sandbox BEFORE July 13, 2026. Starting that week, the New Agent button only opens the new builder.
✅ GA
Agent Script — Deterministic Rules for AI Agents
Agent Script is a new scripting language for AI agents that gives builders precise control by blending deterministic rules with agentic reasoning. Instead of purely probabilistic AI behaviour, you can define guardrails, decision points, and structured paths your agent must follow.
💡 Use Case
A customer service agent must always escalate complaints above Rs 10,000 to a human. With Agent Script, you add a deterministic rule: IF Dispute_Amount > 10000 → transfer to human. The AI cannot override this rule — it's deterministic, not probabilistic.
✅ GA
Agentforce Self-Service — Help Agent in 6 Clicks
Agentforce Self-Service can now be set up in 6 clicks or less and works on the new Portal experience or your website. The new Help Agent cuts through disconnected web pages, dead-end forms, and generic chatbots — delivering resolution-first customer experience.
💡 What's New
Agentforce Self-Service Portal: simplified, agent-first experience with dynamic, personalized, conversational UI. Customer Engagement Agent: independently interacts with and qualifies buyers 24/7 — captures leads that go cold because sales teams can't follow up fast enough.
✅ GA
Hosted MCP Servers — Agentforce via API
Salesforce-hosted Model Context Protocol (MCP) servers are now Generally Available. Any MCP-compatible AI client can connect to a Salesforce org using standard OAuth, accessing sObject operations, Data 360 queries, Tableau analytics, and product APIs — without writing integration code.
💡 What This Enables
Tools like Claude, Cursor, and other AI development environments can now directly connect to your Salesforce org via MCP. Build custom MCP tools from existing Apex actions, flows, and named queries. Headless 360 makes Salesforce fully API and agent-accessible.
⚙️
Apex — API Version 67.0 Security Changes
The most impactful behavioral shift in recent Apex history — action required!
🔴 Critical
Apex v67: Database Operations Now Run in User Mode by Default
From API version 67.0 onward, database operations in Apex run in user mode (not system mode) by default. This means SOQL queries will respect the running user's field-level security and object permissions — previously they ran in system mode and bypassed these checks.
// API v66 behavior (system mode — bypasses FLS)
List<Account> accs = [SELECT Id, Salary__c FROM Account];
// ^ Returns Salary__c even if user can't see it
// API v67 behavior (user mode — respects FLS)
List<Account> accs = [SELECT Id, Salary__c FROM Account];
// ^ Throws FieldAccessException if user doesn't have FLS on Salary__c
// To explicitly run in system mode at v67:
List<Account> accs = [SELECT Id, Salary__c FROM Account WITH SYSTEM_MODE];
⚠️ What You Must Do
1. Run a Tooling API query to find all Apex classes without explicit sharing declarations: SELECT Id, Name, ApiVersion FROM ApexClass WHERE ApiVersion < 63.02. Add explicit with sharing or without sharing declarations to all classes
3. Test in sandbox — users may lose access to data they could previously see
🔴 Critical
Apex v67: Classes Without Sharing Declaration Default to "with sharing"
If an Apex class at API v67.0 has NO sharing declaration (no "with sharing", "without sharing", or "inherited sharing"), it now defaults to "with sharing" instead of the previous implicit "without sharing" behaviour.
// BEFORE v67 — no declaration = effectively without sharing (risky!)
public class AccountService {
public static List<Account> getAll() {
return [SELECT Id FROM Account]; // Could see records user shouldn't
}
}
// AFTER v67 — no declaration = with sharing (secure by default)
// Same class now respects sharing rules
// BEST PRACTICE — always be explicit at ANY API version:
public with sharing class AccountService { // Explicit — recommended }
public without sharing class IntegrationService { // Only if you need system access }
public inherited sharing class SharedService { // Inherits caller's sharing context }
❌ Deprecated
WITH SECURITY_ENFORCED — Deprecated in v67
The WITH SECURITY_ENFORCED SOQL clause is deprecated in API v67.0. Salesforce is promoting explicit use of USER_MODE or SYSTEM_MODE instead of the SOQL clause approach.
// DEPRECATED in v67 — avoid this:
[SELECT Id, Name FROM Account WITH SECURITY_ENFORCED]
// USE THIS INSTEAD — Database.query with user mode:
[SELECT Id, Name FROM Account WITH USER_MODE]
// Or explicitly pass mode in Database methods:
Database.query('SELECT Id FROM Account', AccessLevel.USER_MODE);
🆕 New
Apex Triggers Always Run in System Mode — All API Versions
Apex triggers now always run in system mode across ALL API versions. Previously there were edge cases where sharing rules were enforced in triggers. Sharing or access mode declarations on triggers are no longer permitted. This simplifies trigger behavior and makes it predictable.
💡 Impact
Triggers always see all records regardless of the running user's sharing settings. This is the existing behavior for most orgs — but now it's enforced consistently. Remove any sharing declarations from your trigger files.
🆕 New
Apex Multiline Strings + String.template() Method
Apex now supports multiline strings and a new String.template() method for string interpolation. This makes large text blocks — email bodies, JSON payloads, debug messages, HTTP request bodies — much easier to write and maintain without ugly string concatenation.
// BEFORE — ugly string concatenation
String body = 'Dear ' + contact.Name + ',\n' +
'Your order ' + order.Id + ' has been placed.\n' +
'Amount: Rs ' + order.Amount__c;
// AFTER v67 — multiline strings with template interpolation
String body = String.template(
"""
Dear ${contact.Name},
Your order ${order.Id} has been placed.
Amount: Rs ${order.Amount__c}
"""
);
⚡
LWC — Summer '26 is a Maturity Release
State Manager GA, Live Preview GA, Dynamic Lists, Custom LWCs in Dashboards
✅ GA
LWC State Manager — State Lives Outside Your Components
State Managers are now Generally Available. They let developers separate state and related logic from the component UI itself — pulling data and business logic out of components into a reusable, testable, shared layer. Multiple components on the same page share state without prop drilling or complex event chains.
💡 Why This Is a Big Deal
Previously: Component A updates data → fires an event → Component B listens → updates → fires another event → Component C listens... messy prop-drilling chains. Now: all components subscribe to the same State Manager — data flows cleanly and testably. Think of it like a lightweight Salesforce equivalent of React's Context API or Redux.
// Define a State Manager (myStateManager.js)
import { createStateManager } from 'lwc';
export const cartState = createStateManager({
items: [],
total: 0
});
// Use in any component — no prop drilling needed!
import { cartState } from 'c/myStateManager';
// Both ComponentA and ComponentB share the same cart state
✅ GA
Live Preview in VS Code — Real-Time LWC Preview Without Reload
Previously called "Lightning Preview" or "Local Dev", the renamed Live Preview extension is now GA. Developers can preview a single Lightning Web Component updating in real time — in the browser or directly in Visual Studio Code — without reloading the entire Lightning page. This has been one of the most requested features since LWC launched.
💡 How to Enable
Install the Salesforce Extensions for VS Code → enable the Live Preview extension → edit your LWC component → see changes reflected instantly in a side panel without a full page reload.
✅ GA
Custom LWCs in Dashboards — Interactive Real-Time Data Views
You can now embed custom Lightning Web Components directly into Lightning dashboards. This enables interactive, real-time data views that go far beyond standard chart types — custom maps, custom charts, interactive tables, real-time feeds all possible inside a Salesforce dashboard.
💡 Use Cases
Embed a Leaflet.js map showing account locations inside a dashboard. Add a real-time order tracking widget. Create a custom KPI scorecard with conditional formatting beyond what standard dashboard components support.
🔶 Developer Preview
Dynamic Lists — Virtualized Rendering for Massive Datasets
New lightning-dynamic-list-container and lightning-dynamic-list-item components handle massive data sets with virtualized rendering — items load as you scroll, with built-in focus preservation and comprehensive accessibility support. Previously, loading thousands of records in an LWC list caused performance issues.
🔄
Flow & Automation — Cleaner, More Powerful
Fault path collapse, batch size control, Flow Orchestration now free, and more
🆕 New
Fault Path Collapse — Cleaner Flow Canvas
Building on Spring '26's ability to collapse Decision and Loop elements, Summer '26 extends the same collapse capability to fault paths. Complex flows with extensive error-handling logic can now be collapsed to keep the canvas clean and focused — expand only when you need to work on error handling.
💡 Impact
Large production-grade flows with dozens of fault paths were nearly impossible to navigate visually. Now you can collapse all fault handling and focus on the happy path while maintaining, making flow maintenance significantly less painful.
🆕 New
Scheduled Flow — Configurable Maximum Batch Size
Schedule-triggered flows now let you configure a maximum batch size, overriding the default of 200 records per batch. This gives admins and architects much finer control over how flows process large datasets and reduces the risk of hitting Apex governor limits.
💡 Example
Flow processes 7 records, max batch size = 2 → Salesforce runs 4 batches automatically. Smaller batches = lower governor limit risk per batch. Note: setting too low increases total processing time — calibrate based on your flow complexity.
✅ GA — Now Free!
Flow Orchestration — Now Included in All Editions at No Cost
Flow Orchestration is now a standard feature — orchestration runs are included in Enterprise, Performance, Unlimited, and Developer editions with no usage-based limitations. Previously, orchestration run entitlements were limited and incurred additional cost.
💡 What Is Flow Orchestration?
Multi-step, multi-user, multi-stage business process automation — like an approval chain but for complex workflows. Stage 1 (data entry by rep) → Stage 2 (manager review) → Stage 3 (legal review) → Stage 4 (final approval). All coordinated in a single Flow Orchestration, now available to all Enterprise+ customers.
🆕 New
External Services — Support for Enums in OpenAPI Specs
You can now include enums in the OpenAPI specification used to create an External Service. When added to a Flow action element, the enum appears as a picklist — making external API integration in Flow much cleaner and less error-prone for string-based values.
🛠️
Developer Tools — Web Console, Agentforce Vibes 2.0
Build, debug, and deploy without leaving your browser
🔶 Beta
Web Console (Beta) — Full IDE Inside Salesforce
Web Console is a full IDE that runs inside your Salesforce org, right in the browser. Write, debug, and deploy Apex, LWC, and other metadata without leaving Salesforce. Edit and save classes, run anonymous Apex, build SOQL queries, configure trace flags and debug log levels — all in one place.
💡 How to Enable
Setup → Quick Find → Development → Web Console (Beta) → Enable Web Console (Beta) → refresh browser. Web Console also opens automatically when you access Apex Classes, Apex Triggers, or Apex Jobs pages in Setup. Available to ALL orgs at no cost.
🔧 Web Console vs Agentforce Vibes IDE
Web Console: available on every org, loads faster, runs entirely in browser, supports only Salesforce-provided extensions. Agentforce Vibes IDE: richer, extensible environment with AI assistance. Use Web Console for quick in-org edits, Vibes for complex development.
🔶 Developer Preview
Agentforce Vibes 2.0 — AI-Powered Vibe Coding
Agentforce Vibes 2.0 is Salesforce's enterprise vibe coding solution — an agentic development environment that reasons through complex tasks, builds structured implementation plans, and asks clarifying questions before acting. New in 2.0: model flexibility (Claude Sonnet, Claude Opus, GPT-5 support), React support, redesigned multi-tab chat, and Plan Mode.
💡 Abilities & Skills Framework
Vibes 2.0 introduces an Abilities & Skills framework that dynamically activates domain-relevant context (e.g., MCP tools) and reusable, task-level playbooks based on user intent. You stay in control through approvals, permissions, and VS Code diff reviews.
🆕 New
Data Mask & Seed — Now a Core App with PII Detection
Data Mask & Seed is now a core app with a simpler UI, speeding up app development. The new on-core version includes proactive PII detection to save you time and automates mock data injection. Empty sandboxes and sandboxes with PII were delaying critical development cycles — this solves both problems.
💡 Impact for Developers
Spin up a sandbox with realistic, anonymized data in minutes instead of hours. PII detection automatically identifies sensitive fields that should be masked — no manual field-by-field configuration needed.
🛡️
Admin — Key Summer '26 Updates
Chatter off by default, queue sharing control, profile indirect changes visibility
🔴 Important
Chatter Disabled by Default in New Orgs
In Salesforce orgs created in Summer '26 and later, Chatter is turned OFF by default. This does NOT affect existing orgs — Chatter remains enabled where it was before. The writing is on the wall: Salesforce is beginning the phase-out of Chatter in favour of Slack.
⚠️ If You Need Chatter in New Orgs
Setup → Chatter Settings → Enable Chatter. Required for: Case Feed, Experience Cloud sites with Chatter, orgs where Slack is unsupported. Otherwise — start planning your Slack migration.
🆕 New
Profile Indirect Changes — Now Visible Before Saving
When you change permissions in the enhanced profile view, Summer '26 now shows a new view highlighting any indirect (cascade) changes before you save. Previously, saving a permission change could trigger unexpected ripple effects that weren't visible until after the save.
💡 Impact
Much safer permission management for admins. See exactly what else will change before committing — no more surprise FLS or CRUD changes cascading from a profile permission edit.
🆕 New
Queue Record Access — Control Per Queue Individually
Previously, queues granted users access to additional records by default. Summer '26 introduces per-queue control — enable or disable record access on a queue-by-queue basis. Salesforce Admins now have much finer control over who has access to what via queue membership.
🆕 New
Sales Cloud — Goal Currency vs Quantity Based
Sales teams can now define whether goals are currency-based or quantity-based in Summer '26. Previously goals were always amount-based. Now sales teams who want to prioritize new acquisition counts (number of deals) over revenue growth can set quantity-based goals — much more flexibility for diverse sales models.
❌ Retiring
Lightning Sync — Retires August 2026
Lightning Sync is going away in August 2026. You need to migrate to Einstein Activity Capture (EAC) to avoid email and calendar sync failures. Salesforce's Lightning Sync migration tool provides a structured migration path — not a simple switch flip, but a managed process.
⚠️ Migration Steps
1. Enable Einstein Activity Capture in Setup → EAC Settings2. Configure EAC with your Google Workspace or Microsoft 365 connection
3. Migrate users in waves (test users first)
4. Verify email and calendar sync working
5. Disable Lightning Sync after successful EAC migration
🔗
Integration & API — Summer '26
API v67.0, SOAP login() retirement path, GraphQL mutations, Salesforce-to-Salesforce discontinued
🔴 Critical
SOAP login() Retires in Summer '27 — Migrate to OAuth NOW
SOAP login() in API versions 31.0–64.0 retires in Summer '27. Any integration that authenticates with a username and password over SOAP will stop working. This is one of the most impactful changes for integration teams — many legacy integrations still use username/password SOAP auth.
⚠️ Migration Path
Move integrations to OAuth — using external client apps with JWT tokens (Client Credentials or JWT Bearer flow). Summer '26 introduces a new "Any API Auth" user permission to control who can authenticate via SOAP login() — enforced by default in newly created orgs.
// STOP USING — SOAP username/password auth (retiring Summer '27)
// login(username, password) SOAP endpoint
// USE INSTEAD — OAuth JWT Bearer flow
// POST https://login.salesforce.com/services/oauth2/token
// grant_type=urn:ietf:params:oauth:grant-type:jwt-bearer
// assertion=[signed JWT token]
❌ Discontinued
Salesforce-to-Salesforce — Discontinued in Summer '26
Salesforce-to-Salesforce (S2S) support is discontinued in Summer '26, with full retirement enforced in Spring '27. Integrations that use S2S must migrate to: Partner Cloud, Data Cloud One, MuleSoft Anypoint, or MuleSoft for Flow.
⚠️ Are You Using S2S?
Setup → Salesforce to Salesforce → check if any connections are active. If yes — migrate to MuleSoft Anypoint or Data Cloud One before Spring '27 enforcement.
🆕 New
GraphQL API — Mutations Now Reference Earlier Operation Results
GraphQL mutations can now reference any field returned by an earlier operation in the same request — not just its record ID. This enables more powerful, efficient GraphQL queries that chain operations together in a single request.
🌐
Experience Cloud — Summer '26
10 GB file upload, malware scanning GA, AI self-service components
🆕 New
10 GB File Uploads to Experience Cloud Sites
Experience Cloud sites now support uploading files as large as 10 GB to Aura or LWR sites. Previously file size limits made it difficult to use Experience Cloud for file-heavy portals like construction project document sharing or large media file uploads.
✅ GA
Malware Scanning for Salesforce Files — GA
Malware scans for Salesforce Files are now Generally Available in Experience Cloud. Files uploaded through your Experience Cloud sites are automatically scanned for malware before being stored — critical security feature for any public-facing portal accepting file uploads from external users.
🆕 New
AI Self-Service Components for Aura and LWR Sites
A suite of AI-assisted Self-Service components is now available for Aura or LWR Experience Cloud sites — delivering personalized self-service experiences powered by Agentforce. Drop these components into your portal to add AI-powered help, case deflection, and guided resolution without custom development.

FAQ 5
Is Lightning Sync retiring in 2026? What do I do?
Yes — Lightning Sync retires in August 2026. Migrate to Einstein Activity Capture (EAC) before that date to avoid email and calendar sync failures.
EAC advantages over Lightning Sync: Auto-logs emails without rep action, bidirectional calendar sync, Einstein AI insights, supports Google Workspace and Microsoft 365.
How to migrate: Setup → Einstein Activity Capture Settings → enable → connect your Google Workspace or Microsoft 365 → configure sync rules → migrate users in waves → verify → disable Lightning Sync.

FAQ 6
What is LWC State Manager in Salesforce Summer '26?
LWC State Manager became Generally Available in Summer '26. It separates shared state and logic from component UI into a reusable shared layer — multiple Lightning Web Components subscribe to the same State Manager and update automatically when state changes.
Before State Manager: Component A fires event → parent listens → passes property → Component B updates → fires another event. Complex, tightly coupled chains.
With State Manager: All components import the same State Manager. One component updates state → all subscribers re-render automatically. No event chains. No prop drilling. Similar to React Context API or Redux for LWC.

FAQ 7
What is Multi-Agent Orchestration in Agentforce Summer '26?
Multi-Agent Orchestration enables multiple Agentforce AI agents to work as a coordinated team on complex end-to-end workflows. Previously agents worked in isolation. Now Agent 1 completes a task and hands off to Agent 2 with full context.
Example: Prospecting Agent finds leads → Qualification Agent scores them → Scheduling Agent books meetings — all automated, no human handoff. A single seller gets a full AI team working behind them without adding headcount.
Agents communicate via Agent Script — a new scripting language that blends deterministic rules with AI reasoning for precise workflow control.

FAQ 8
Is Flow Orchestration free in Summer '26?
Yes! Flow Orchestration is now a standard feature included in Enterprise, Performance, Unlimited, and Developer editions at no additional cost — with no usage-based limitations. Previously orchestration runs were limited and cost extra.
Flow Orchestration enables multi-step, multi-user workflows where different people complete different stages in sequence — loan approvals, employee onboarding, deal review chains — all now available to every Enterprise+ customer at no extra cost.

FAQ 10
When does SOAP login() retire and what is the migration path?
SOAP login() in API versions 31.0–64.0 retires in Summer '27 (announced in Summer '26). All integrations using username and password SOAP authentication will stop working after this date.
Migration path: Move to OAuth JWT Bearer flow using external client apps — create a Connected App, generate RSA certificate, sign JWT with private key, exchange JWT for access token, use access token for API calls.
Summer '26 also introduced the "Any API Auth" user permission to control who can still authenticate via SOAP login() — enforced by default in new orgs. Start your migration now — Summer '27 is approaching.

Summer '26 Interview Questions
10 questions interviewers will ask based on Summer '26 — prepare these now
IQ1
What are the two major Apex security changes in Summer '26 API v67.0 and what is their impact?
✓ Direct Answer
Two breaking changes: (1) Database operations now default to USER MODE — SOQL queries respect the running user's FLS and CRUD permissions. (2) Classes without explicit sharing declarations now default to WITH SHARING. Both are security improvements but can break code that relied on implicit system mode.Impact: SOQL that returned restricted fields now throws FieldAccessException. Classes without sharing declarations may restrict data access. WITH SECURITY_ENFORCED is deprecated — replace with WITH USER_MODE.
Fix: Add explicit 'with sharing' or 'without sharing' to all classes. Replace WITH SECURITY_ENFORCED with WITH USER_MODE. Test in Summer '26 sandbox first.
Fix: Add explicit 'with sharing' or 'without sharing' to all classes. Replace WITH SECURITY_ENFORCED with WITH USER_MODE. Test in Summer '26 sandbox first.
// BEFORE v67 — implicit, risky
public class MyService { // implicit without sharing
return [SELECT Id, Salary__c FROM Account WITH SECURITY_ENFORCED];
}
// AFTER v67 — explicit, correct
public with sharing class MyService {
return [SELECT Id, Salary__c FROM Account WITH USER_MODE];
}
public without sharing class IntegrationService { } // when system access needed
🎤 One-Liner for Interview
"Summer '26 API v67 makes Apex secure by default — USER MODE for database ops, WITH SHARING for undeclared classes. It's breaking for code relying on implicit system mode — every class needs explicit sharing declaration now."
IQ2
What is LWC State Manager (GA in Summer '26) and why is it better than event-based communication?
✓ Direct Answer
LWC State Manager allows developers to separate shared state and logic from component UI into a reusable shared layer. Multiple components subscribe to the same State Manager and update automatically when state changes — no event chains, no prop drilling.Before State Manager: Component A changes data → fires custom event → parent listens → passes property down → Component B gets update → fires another event. Complex, tightly coupled, hard to debug.
With State Manager: All components import the same State Manager. When one component updates state, all subscribers re-render automatically. Cleaner, testable, reusable — similar to React Context API or Redux.

// Define shared state once (cartStateManager.js)
import { createStateManager } from 'lwc';
export const cartState = createStateManager({ items: [], total: 0 });
// ComponentA.js — update state
import { cartState } from 'c/cartStateManager';
cartState.items = [...cartState.items, newItem]; // ComponentB auto-updates
// No events needed between siblings — state is shared
🎤 One-Liner for Interview
"LWC State Manager GA in Summer '26 pulls shared state out of components into a subscribable layer — multiple components share state without event chains. Think Salesforce's answer to React Context API."
IQ3
What is Multi-Agent Orchestration in Agentforce Summer '26 and what business problem does it solve?
✓ Direct Answer
Multi-Agent Orchestration enables multiple Agentforce AI agents to work together as a coordinated team. Agent 1 completes a task and hands off to Agent 2 with full context — like a relay race. Previously each agent worked independently on isolated tasks.Problem it solves: Complex sales/service workflows need multiple specialized skills — prospecting, qualification, scheduling, follow-up. A single generalist agent is less accurate. Humans coordinating between steps is slow.
Solution: Prospecting Agent finds leads → Qualification Agent scores them → Scheduling Agent books meetings — all automated, coordinated, no human handoff needed. One seller gets a full AI team.

🎤 One-Liner for Interview
"Multi-Agent Orchestration in Summer '26 lets Agentforce agents work as a coordinated team — each specializes in one task and hands off to the next with full context, enabling complex end-to-end workflows no single agent could handle reliably."
IQ4
What is a Hosted MCP Server in Summer '26 and how does it change how AI tools interact with Salesforce?
✓ Direct Answer
Salesforce-hosted MCP (Model Context Protocol) servers are GA in Summer '26. Any MCP-compatible AI client — Claude, Cursor, GitHub Copilot — can connect to your Salesforce org via standard OAuth and access sObjects, Data 360, Tableau, and custom Apex actions without writing integration code.Before MCP: To connect an AI tool to Salesforce, you needed custom REST API integration, credential management, and manual tool definitions.
With Hosted MCP: AI client authenticates via OAuth to Salesforce's MCP server → can read/write Salesforce data, run Apex, execute flows — all via standard MCP protocol. Build custom MCP tools from existing Apex actions and flows.
Part of Headless 360: Salesforce's strategy to make every capability accessible as API, MCP tool, or CLI command — to any authenticated caller (human, app, or AI agent).

What is Web Console (Beta) in Summer '26 and how is it different from Developer Console?
✓ Direct Answer
Web Console is a modern in-browser IDE inside Salesforce — write Apex, run SOQL, set trace flags and debug log levels, all in one place. It's faster and more modern than the legacy Developer Console. Available to all orgs at no cost. Enable in Setup → Development → Web Console (Beta).Differences from Developer Console:
Web Console: modern, fast, auto-opens from Apex Setup pages (Apex Classes, Triggers, Jobs), consolidates SOQL + Apex + trace flags in one place.
Developer Console: legacy technology, slower to load, separate tabs for different tools.
Web Console vs Agentforce Vibes IDE: Web Console is available on every org, loads fast, browser-only, Salesforce extensions only — ideal for quick edits. Vibes IDE is AI-powered, extensible, richer — ideal for complex development.

IQ7
What is the significance of Chatter being disabled by default in new orgs from Summer '26?
✓ Direct Answer
It signals Salesforce's strategy to phase out Chatter in favor of Slack. New orgs from Summer '26 have Chatter off by default — you can still enable it. Existing orgs are unaffected. For new implementations, default to Slack First Sales integration rather than Chatter.When you still need Chatter in new orgs: Case Feed depends on Chatter. Experience Cloud sites with Chatter functionality. Orgs where Slack is unsupported.
Enable in new orgs if needed: Setup → Chatter Settings → Enable Chatter.
Strategic meaning: Salesforce is betting on Slack as the collaboration layer. Summer '26 also introduced Slack First Sales — bringing CRM context to sellers in Slack with Agentforce Sales in Slack. Start planning Slack migration roadmaps.

IQ8
What is Apex Multiline Strings and String.template() in Summer '26 and when would you use it?
✓ Direct Answer
Summer '26 (API v67) adds multiline string literals using triple quotes and String.template() for variable interpolation — eliminating verbose string concatenation for email templates, JSON payloads, HTTP request bodies, and debug messages.Before: String body = 'Hello ' + name + ',\n' + 'Your order ' + orderId + ' is confirmed.';
After: Clean multiline string with ${variable} interpolation.
Use cases: Email bodies, JSON request payloads for HTTP callouts, debug messages, dynamic SOQL strings, generated text content.
After: Clean multiline string with ${variable} interpolation.
Use cases: Email bodies, JSON request payloads for HTTP callouts, debug messages, dynamic SOQL strings, generated text content.
// BEFORE — messy concatenation
String body = 'Hello ' + contact.FirstName + ',\nOrder ' + order.Name + ' confirmed.';
// AFTER v67 — clean multiline template
String body = String.template(
"""
Hello ${contact.FirstName},
Order ${order.Name} worth Rs ${order.Amount__c} confirmed.
Thank you!
"""
);

IQ9
Why is Flow Orchestration becoming free in Summer '26 significant for architects?
✓ Direct Answer
Flow Orchestration is now included in Enterprise, Performance, Unlimited, and Developer editions at no additional cost — removing previous usage-based limitations. This makes complex multi-step, multi-user workflow automation accessible to all Enterprise+ customers without cost concerns.What Flow Orchestration enables: Multi-stage workflows where different users complete different stages in sequence. Example: Seller submits deal → Manager reviews (Stage 1) → Legal reviews (Stage 2) → Finance approves (Stage 3) → Deal activates. Each stage is a separate Flow coordinated by the Orchestration.
Why free matters: Previously usage-based costs limited adoption to high-value use cases only. Now architects can use it for any complex multi-user workflow — loan approvals, employee onboarding, compliance review chains — without justifying cost per orchestration run.

IQ10
What is the SOAP login() retirement announced in Summer '26 and how do you migrate integrations to OAuth?
✓ Direct Answer
SOAP login() in API versions 31.0–64.0 retires in Summer '27 (announced in Summer '26). Any integration authenticating with username and password over SOAP will stop working. Migrate to OAuth — specifically JWT Bearer flow or Client Credentials flow using external client apps.Who is affected: Legacy ERP integrations, middleware, ETL tools using basic SOAP auth (username + password).
Migration to OAuth JWT Bearer:
1. Create Connected App (external client app) in Salesforce
2. Generate RSA certificate — upload public key to Connected App
3. In your integration: create JWT (iss=client_id, sub=username, aud=login URL, exp=timestamp)
4. Sign JWT with private key
5. POST to token endpoint: grant_type=jwt-bearer, assertion=signed_JWT
6. Use returned access_token for all API calls
Summer '26 addition: New 'Any API Auth' permission controls who can still use SOAP login() — enforced by default in new orgs.
