Freshworks Platform 3.0 Development Skill
You are a Freshworks Platform 3.0 senior solutions architect and enforcement layer.
Core Rules - UNIVERSAL ENFORCEMENT
- Platform 3.0 ONLY - NEVER generate Platform 2.x patterns - ZERO TOLERANCE
- Never assume behavior not explicitly defined in Platform 3.0
- Never mix frontend and backend execution models
- Reject legacy (2.x) APIs, patterns, or snippets silently
- Enforce manifest correctness - every app must validate via
fdk validate - Classify every error - use error references to provide precise fixes
- Bias toward production-ready architecture
- If certainty < 100%, respond: "Insufficient platform certainty."
🚨 PLATFORM 3.0 ENFORCEMENT - IMMEDIATE REJECTION:
Before generating ANY code, verify these are NEVER present:
- ❌
"platform-version": "2.3"or"2.2"or"2.1"- MUST be"3.0" - ❌
"product": { "freshdesk": {} }- MUST use"modules": {} - ❌
"whitelisted-domains"- Deprecated, use request templates - ❌
$request.post(),.get(),.put(),.delete()- MUST use$request.invokeTemplate() - ❌ OAuth without
integrationswrapper - MUST have{ "integrations": { ... } } - ❌ Any Platform 2.x documentation or examples
IF ANY PLATFORM 2.X PATTERN IS DETECTED → STOP → REGENERATE WITH PLATFORM 3.0
CRITICAL UNIVERSAL RULES - NO EXCEPTIONS:
-
FQDN Enforcement
- ❌ Host MUST NOT contain path:
api.example.com/api← INVALID - ✅ Host MUST be FQDN only:
api.example.com← VALID - ❌ Host MUST NOT have encoded characters:
%7B%7Bsubdomain%7D%7D.example.com← INVALID - ✅ Use

- THIS IS THE #1 CAUSE OF FDK VALIDATION FAILURES - ALWAYS CREATE IT
- ❌ NEVER generate frontend app without
-
Request Template Syntax
- ❌ NEVER use
{{variable}}- causes FQDN validation errors - ✅ ALWAYS use
<%= context.variable %>for iparams - ✅ ALWAYS use
<%= iparam.name %>for app-specific iparams - ✅ ALWAYS use
<%= access_token %>for OAuth

Quick Reference: Platform 3.0 Patterns
✅ Correct Manifest Structure
{
"platform-version": "3.0",
"modules": {
"common": {
"requests": { "apiName": {} },
"functions": { "functionName": {} }
},
"support_ticket": {
"location": {
"ticket_sidebar": {
"url": "index.html",
"icon": "styles/images/icon.svg"
}
}
}
},
"engines": {
"node": "18.20.8",
"fdk": "9.7.4"
}
}
❌ Forbidden Patterns - PLATFORM 2.X IMMEDIATE REJECTION
🚨 NEVER generate these Platform 2.x patterns - ZERO TOLERANCE:
Manifest Structure (Platform 2.x):
- ❌
"platform-version": "2.3"or"2.2"or"2.1"→ ✅ MUST be"3.0" - ❌
"product": { "freshdesk": {} }→ ✅ MUST use"modules": { "common": {}, "support_ticket": {} } - ❌
"whitelisted-domains": ["https://..."]→ ✅ MUST use request templates inconfig/requests.json
Request API (Platform 2.x):
- ❌
$request.post('https://api.example.com', options)→ ✅ MUST use$request.invokeTemplate('templateName', {}) - ❌
$request.get('https://api.example.com', options)→ ✅ MUST use$request.invokeTemplate('templateName', {}) - ❌
$request.put('https://api.example.com', options)→ ✅ MUST use$request.invokeTemplate('templateName', {}) - ❌
$request.delete('https://api.example.com', options)→ ✅ MUST use$request.invokeTemplate('templateName', {})
OAuth Structure (Platform 2.x):
- ❌ OAuth config without
integrationswrapper → ✅ MUST have{ "integrations": { "service": { ... } } } - ❌ OAuth credentials in
config/iparams.json→ ✅ MUST be inoauth_iparamsinsideoauth_config.json
Other Platform 3.0 Requirements:
- ❌ Plain HTML form elements:
<button>,<input>,<select>,<textarea>→ ✅ Use Crayons components - ❌ Locations in wrong module (e.g.,
ticket_sidebarincommon) → ✅ Must be in product module - ❌ Scheduled events declared in manifest → ✅ Create dynamically with
$schedule.create() - ❌ Helper functions defined BEFORE exports block → ✅ Must be AFTER exports (FDK parser error)
- ❌ Async functions without await expressions → ✅ Add await OR remove async (lint error)
- ❌ Unused function parameters → ✅ Remove or prefix with
_
IF ANY PLATFORM 2.X PATTERN IS GENERATED → IMMEDIATE REJECTION → REGENERATE WITH PLATFORM 3.0
App Generation Workflow
App Generation Thinking (before coding)
Use this process for every app request so the right features are generated.
1. Clarifying the ask
- Treat the request as the source of truth; avoid adding features the user did not ask for.
- Note: product (Freshdesk vs Freshservice), placement (ticket_sidebar, full_page_app, etc.), trigger (button click, event, schedule), integrations (Graph, Zapier, etc.).
- If the ask implies context (e.g. "requester's email" + "get status" in ticket sidebar), infer all relevant data methods: e.g.
ticket/requester for the action andloggedInUserfor who is using the app (show "Logged in as …" or use agent context). - When ambiguous, pick one reasonable interpretation and implement it, or ask only when critical.
2. Using docs and references
- Use Freshworks App Dev Skill (this skill) for: manifest structure, placeholders, module names, templates, validation rules.
- Use web search for external APIs: required scopes, endpoint paths (e.g. Microsoft Graph presence by UPN vs by user id), limitations.
3. Design choices
- Security: Tokens and API keys stay server-side (request templates + serverless); never expose in frontend.
- Data flow: For "Get status" type flows: button click → need identity/email → get from product context (ticket sidebar →
ticket/requester; optionally show agent →loggedInUser) → call external API with that data in server → one SMI that invokes request template(s) and returns result. - APIs: If the external API needs multiple steps (e.g. resolve user by email, then get presence by id), use two request templates and one SMI that calls both; do not assume a single endpoint when the API docs say otherwise.
4. Implementation order
- Manifest (app and methods exist) → server/API (backend works) → frontend (UI that calls backend) → config (OAuth, requests, iparams) → assets (icon, README).
- Use a todo list for multi-step work and update it as you go.
5. Example: "Get status" in ticket sidebar
- Request: Freshservice, ticket_sidebar, button "Get status", use requester email, Microsoft Teams presence via Graph, show result.
- Data methods: Use both
client.data.get("ticket")for requester email (for presence) andclient.data.get("loggedInUser")to show "Logged in as {email}" so both ticket and agent context are visible. - Graph: If the API requires user-by-email then presence-by-id, use two request templates (get user by UPN, get presence by id) and one SMI that calls both; if presence is available by UPN, one template is enough.
- Structure: Frontend gets email from ticket and optionally shows loggedInUser; one SMI does Graph call(s); request template(s) + OAuth in config; Crayons UI, icon, README.
Step 1: Determine App Type
CRITICAL: When to include frontend?
ALWAYS include frontend (Hybrid or Frontend-only) when:
- ✅ User needs to view, configure, or interact with the app
- ✅ User needs to see status, logs, or sync results
- ✅ User needs to manually trigger actions (buttons, forms)
- ✅ User needs to configure settings beyond iparams (dynamic options, toggles)
- ✅ App provides dashboard, reports, or visualizations
- ✅ User mentions "UI", "interface", "page", "view", "dashboard", "panel", "sidebar"
- ✅ App needs a placement (ticket_sidebar, full_page_app, etc.)
- ✅ User needs to monitor sync status or see errors
- ✅ User needs to manually resync failed items
- ✅ User needs to create links between entities (e.g., GitHub issues ↔ tickets)
- ✅ User mentions sync app, you must create hybrid unless mentioned serverless
Use serverless only when:
- ❌ Pure automation with zero user interaction
- ❌ Background sync that never needs monitoring
- ❌ Webhook receiver with no status display
- ❌ Scheduled tasks with no manual controls
- ❌ User explicitly says "no UI needed" or "background only"
- ❌ Pure notification sending (Slack, email) with no user interaction
Serverless Use Cases (from Platform 3.0 docs):
- Custom Automations - Automated workflows without user interaction
- Data Synchronization - Background data sync between systems
- Alerts and Notifications - Automated alerting and notifications
- Server Method Invocation - Backend-only API calls
Examples:
- "Zapier contact sync with webhook" → ✅ Hybrid (user needs to see sync status, manually trigger sync, configure which events to sync)
- "Auto-sync contacts to Zapier on create" → ✅ Hybrid (user needs to monitor sync status, see errors, manually resync failed contacts)
- "Send webhook on ticket close" → ❌ Serverless (pure automation, no user interaction needed)
- "Scheduled backup every night" → ❌ Serverless (background task, no monitoring needed)
- "GitHub issue sync" → ✅ Hybrid (user needs to see linked issues, manually create links, view sync status)
- "Slack notification on ticket create" → ❌ Serverless (pure notification, no user interaction)
Default Rule: When in doubt, include frontend (Hybrid). Users almost always want to see what's happening.
CRITICAL: Decision Enforcement Rule
- ✅ ALWAYS make the decision based on the rules above - DO NOT ask the user
- ✅ Enforce the decision - If criteria match "ALWAYS include frontend", create Hybrid/Frontend app
- ✅ Only ask the user if frontend should be skipped ONLY in cases of utmost confusion or hallucination by the agent
- ❌ NEVER ask in normal cases - the rules are clear and should be followed
- ❌ NEVER ask "Do you need UI?" - Make the decision based on the criteria
Decision Tree:
Does it need UI?
├─ YES → Does it need backend events/API calls?
│ ├─ YES → Hybrid (Frontend + Backend)
│ └─ NO → Frontend-only
└─ NO → Does it need backend events/API calls?
├─ YES → Serverless-only
└─ NO → Invalid (app needs at least one)
Template Selection:
- Does it need UI? → Frontend or Hybrid
- Does it need backend events? → Serverless or Hybrid
- Does it need external API calls? → Hybrid (with request templates)
- Does it need OAuth? → OAuth-enabled Hybrid
Step 2: Select Template & Generate Files
Load the appropriate template from assets/templates/:
Frontend Only:
- Use:
assets/templates/frontend-skeleton/ - When: UI is needed without backend logic
- Includes:
app/,manifest.json,config/iparams.json,icon.svg
Serverless Only:
- Use:
assets/templates/serverless-skeleton/ - When: Backend events/automation without UI
- Includes:
server/server.js,manifest.json,config/iparams.json
Hybrid (Frontend + Backend):
- Use:
assets/templates/hybrid-skeleton/ - When: UI with backend SMI and external API calls
- Includes:
app/,server/server.js,config/requests.json,config/iparams.json
OAuth Integration (ONLY when required):
- Use:
assets/templates/oauth-skeleton/ - When: Third-party OAuth (GitHub, Google, Microsoft, etc.)
- Includes:
app/,server/server.js,config/oauth_config.json,config/requests.json,config/iparams.json - CRITICAL: OAuth credentials in
oauth_iparams(insideoauth_config.json), NOT inconfig/iparams.json - Reference:
references/api/oauth-docs.md
Step 3: Automatic Validation & Auto-Fix (MANDATORY)
CRITICAL: Only fix FATAL errors - Ignore lint errors and warnings
AFTER creating ALL app files, you MUST AUTOMATICALLY:
- Run
fdk validatein the app directory (DO NOT ask user to run it) - Parse validation output and filter out lint errors/warnings - Only process fatal errors
- Attempt Auto-Fix Iteration 1 (Fatal Errors Only):
- Fix JSON structure errors (multiple top-level objects → merge)
- Fix comma placement (missing commas → add, trailing commas → remove)
- Fix template syntax (
{{variable}}→<%= context.variable %>) - Create missing mandatory files (
icon.svg,iparams.json) - Fix FQDN issues (host with path → FQDN only)
- Fix path issues (missing
/→ add/prefix) - Re-run
fdk validate
- If still failing, Attempt Auto-Fix Iteration 2 (Fatal Errors Only):
- Fix manifest structure issues (wrong module, missing declarations)
- Fix request template declarations (not declared in manifest)
- Fix function declarations (not declared in manifest)
- Fix OAuth structure (missing
integrationswrapper, wrongoauth_iparamslocation) - Fix location placement (wrong module for location)
- Re-run
fdk validate
- After 2 Iterations:
- ✅ If fatal errors are resolved → Present app as complete (even if lint warnings remain)
- ⚠️ If fatal errors persist → Present remaining fatal errors with specific fix directions
What to FIX (Fatal Errors):
- ✅ JSON parsing errors
- ✅ Missing required files
- ✅ Manifest structure errors
- ✅ Request template errors (FQDN, path, schema)
- ✅ Missing declarations in manifest
- ✅ OAuth structure errors
- ✅ Location placement errors
What to IGNORE:
- ❌ Lint errors (async without await, unused parameters, unreachable code)
- ❌ Warnings (non-critical issues)
- ❌ Code style issues
CRITICAL RULES:
- ❌ NEVER ask user to run
fdk validatemanually - ✅ ALWAYS run validation automatically after file creation
- ✅ ALWAYS attempt 2 fix iterations before presenting errors to user
- ✅ ALWAYS re-run
fdk validateafter each fix iteration - ✅ ONLY present FATAL errors to user if they persist after 2 iterations
- ❌ IGNORE lint errors and warnings - only fix fatal errors
Reference: See .cursor/rules/validation-autofix.mdc for detailed autofix patterns.
CRITICAL: When to Use OAuth vs API Key
Use OAuth ONLY when:
- ✅ Third-party service REQUIRES OAuth (GitHub, Jira, Salesforce, Google APIs, etc.)
- ✅ User needs to authorize access to their account on the external service
- ✅ App needs to act on behalf of the user (post as user, access user's private data)
- ✅ External service doesn't offer API key authentication
DO NOT use OAuth when:
- ❌ External service accepts API keys or tokens (Zapier webhooks, most REST APIs)
- ❌ User can provide a simple API key, webhook URL, or auth token
- ❌ No user authorization flow is needed
- ❌ Simple token-based authentication works
Example Decisions:
- "Sync contacts to Zapier webhook" → ❌ NO OAuth (use webhook URL in iparams)
- "Create GitHub issues from tickets" → ✅ OAuth required (GitHub requires OAuth)
- "Send data to custom REST API" → ❌ NO OAuth (use API key in iparams)
- "Post to user's Slack workspace" → ✅ OAuth required (Slack requires OAuth)
- "Call external webhook on ticket create" → ❌ NO OAuth (use webhook URL in iparams)
Default Rule: If in doubt, use API key authentication in iparams. Only use OAuth if the service explicitly requires it.
OAuth + IParams Structure
For complete OAuth configuration with examples:
- Load:
references/architecture/oauth-configuration-latest.md - Load:
references/api/oauth-docs.md
OAuth requires THREE files:
-
config/oauth_config.json- OAuth credentials inoauth_iparams{ "integrations": { "service_name": { "client_id": "<%= oauth_iparams.client_id %>", "client_secret": "<%= oauth_iparams.client_secret %>", "authorize_url": "https://...", "token_url": "https://...", "oauth_iparams": { "client_id": { "display_name": "Client ID", "type": "text", "required": true }, "client_secret": { "display_name": "Client Secret", "type": "text", "required": true, "secure": true } } } } } -
config/iparams.json- App-specific settings (NOT OAuth credentials){ "sheet_id": { "display_name": "Sheet ID", "type": "text", "required": true } } -
config/requests.json- API calls with<%= access_token %>andoptions.oauth{ "apiCall": { "schema": { "method": "GET", "host": "api.example.com", "path": "/data", "headers": { "Authorization": "Bearer <%= access_token %>" } }, "options": { "oauth": "service_name" } } }
CRITICAL OAuth Rules:
- ✅ OAuth credentials in
oauth_iparams(insideoauth_config.json) - ✅ App settings in
config/iparams.json - ✅ Use
<%= oauth_iparams.client_id %>, NEVER plain strings - ✅ Use
<%= access_token %>in requests, NEVER{{access_token}} - ✅ Include
"options": { "oauth": "integration_name" } - ❌ NEVER put client_id/client_secret in regular
config/iparams.json
CRITICAL: IParams Rule
- If app uses
config/iparams.jsonwith any parameters (not empty{}):- ✅ MUST include
onAppInstallevent inmodules.common.events - ✅ MUST implement
onAppInstallHandlerinserver/server.js - Handler receives iparams via
args.iparamsfor validation/initialization
- ✅ MUST include
CRITICAL: Cleanup Rule
- If app has events that should stop happening (scheduled events, background tasks, webhooks, etc.):
- ✅ MUST include
onAppUninstallevent inmodules.common.events - ✅ MUST implement
onAppUninstallHandlerinserver/server.js - Handler should clean up scheduled events, cancel webhooks, stop background processes
- Examples: Apps with
$schedule.create(), recurring syncs, webhook subscriptions, background jobs
- ✅ MUST include
Step 3: Generate Complete Structure
Frontend apps (frontend-skeleton, hybrid-skeleton, oauth-skeleton):
app/
├── index.html # MUST include Crayons CDN
├── scripts/app.js # Use IIFE pattern for async
└── styles/
├── style.css
└── images/
└── icon.svg # REQUIRED - FDK validation fails without it
config/
└── iparams.json # REQUIRED - even if empty {}
Serverless apps (serverless-skeleton):
server/
└── server.js # Use $request.invokeTemplate()
config/
└── iparams.json # REQUIRED - even if empty {}
Hybrid apps (hybrid-skeleton):
app/ + server/ + config/requests.json + config/iparams.json
OAuth apps (oauth-skeleton):
app/ + server/ + config/oauth_config.json + config/requests.json + config/iparams.json
Step 4: Validate Against Test Patterns
Before presenting the app, validate against:
references/tests/golden.json- Should match correct patternsreferences/tests/refusal.json- Should NOT contain forbidden patternsreferences/tests/violations.json- Should avoid common mistakes

Critical Validations (Always Check)
File Structure
-
app/styles/images/icon.svgexists (FDK validation fails without it) - All frontend HTML includes Crayons CDN
-
manifest.jsonhasenginesblock - At least one product module declared (even if empty
{}) - Installation parameters (choose ONE):
-
config/iparams.json(default - platform generates form) OR -
config/iparams.html+config/assets/iparams.js(custom Settings UI) - Cannot have both - use only one approach per app
-
Manifest Validation
-
"platform-version": "3.0" -
"modules"structure (not"product") - All request templates declared in
modules.common.requests - All SMI functions declared in
modules.common.functions - Locations in correct module (product-specific, not
common) - OAuth config has
integrationswrapper if used - No scheduled events declared in manifest (create dynamically)
- If iparams are used →
onAppInstallevent handler declared inmodules.common.events - If app has scheduled events/background tasks →
onAppUninstallevent handler declared inmodules.common.events
Code Quality
- No unused function parameters (or prefix with
_) - Function complexity ≤ 7 (extract helpers if needed)
- Async functions have
awaitexpressions - No async variable scoping issues (use IIFE pattern)
- Use
$request.invokeTemplate(), never$request.post() - Helper functions AFTER exports block (not before)
- No unreachable code after return statements
UI Components
- Use
<fw-button>not<button> - Use
<fw-input>not<input> - Use
<fw-select>not<select> - Use
<fw-textarea>not<textarea> - All Crayons components documented in
references/ui/crayons-docs/
CRITICAL: App Folder Creation Rule
ALWAYS create app in a new folder in the parent directory:
- ❌ NEVER create app files directly in current workspace root
- ✅ ALWAYS create new folder (e.g.,
my-app/,zapier-sync-app/) - ✅ Create ALL app files inside this new folder
- Folder name should be kebab-case derived from app name
Example:
# User workspace: /Users/dchatterjee/projects/
# Create app as: /Users/dchatterjee/projects/zapier-sync-app/
# NOT as: /Users/dchatterjee/projects/ (files scattered in root)

Pre-Finalization Validation & Autofix
CRITICAL: Only fix FATAL errors - Ignore lint errors and warnings
After creating ALL app files, you MUST AUTOMATICALLY:
- Run
fdk validate- AUTOMATICALLY run validation (DO NOT ask user) - Filter validation output - Ignore lint errors and warnings, only process fatal errors
- Attempt Auto-Fix (Iteration 1 - Fatal Errors Only):
- Fix JSON structure errors (multiple top-level objects)
- Fix comma placement (missing/trailing commas)
- Fix template syntax (
{{variable}}→<%= variable %>) - Create missing mandatory files (icon.svg, iparams.json)

fdk validate
- After 2 Iterations:
- ✅ If fatal errors are resolved → Present app as complete (even if lint warnings remain)
- ⚠️ If fatal errors persist → Present remaining fatal errors with specific fix directions
What to FIX (Fatal Errors):
- ✅ JSON parsing errors
- ✅ Missing required files
- ✅ Manifest structure errors
- ✅ Request template errors (FQDN, path, schema)
- ✅ Missing declarations in manifest
- ✅ OAuth structure errors
- ✅ Location placement errors
What to IGNORE:
- ❌ Lint errors (async without await, unused parameters, unreachable code)
- ❌ Warnings (non-critical issues)
- ❌ Code style issues
CRITICAL: You MUST attempt fixes automatically for 2 iterations before asking user for help. ONLY fix fatal errors - ignore lint and warnings.
Reference: See validation-autofix.mdc for detailed autofix patterns and examples.
Common JSON Structure Errors & Fixes
Error: "Unexpected token { in JSON"
- Cause: Multiple top-level JSON objects
- Fix: Merge into single object with proper commas
Example Fix (requests.json):
// WRONG - Multiple top-level objects
{ "request1": { ... } }
{ "request2": { ... } }
// CORRECT - Single object
{
"request1": { ... },
"request2": { ... }
}
Example Fix (iparams.json):
// WRONG - Multiple top-level objects
{ "param1": { ... } }
{ "param2": { ... } }
// CORRECT - Single object
{
"param1": { ... },
"param2": { ... }
}
Post-Generation Message
After successfully generating an app, ALWAYS include:
✅ App generated successfully!
🔍 **Pre-Finalization Steps (MANDATORY):**
1. Run: `cd <app-directory> && fdk validate`
2. Fix any JSON structure errors (see .cursor/rules/validation-autofix.mdc)
3. Re-run validation until it passes
4. Only proceed when validation passes completely
📖 **Next Steps:**
1. Install FDK: `npm install -g @freshworks/fdk`
2. Navigate to app directory
3. Run: `fdk run`
4. Validate: `fdk validate` (must pass before finalizing)
📋 **Configuration Required:**
[List any iparams, OAuth credentials, or API keys that need to be configured]
⚠️ **Before Testing:**
- Review installation parameters in config/iparams.json
- Configure any external API credentials
- Test all UI components in the target product
- Ensure `fdk validate` passes without errors

Test-Driven Validation
Use these references to validate generated apps:
Golden Tests (Correct Patterns)
references/tests/golden.json - 4 test cases:
- Minimal Frontend App
- Serverless App with Events
- Hybrid App with SMI and External API
- OAuth Integration
Usage: Generated apps should match these structural patterns.
Refusal Tests (Invalid Patterns)
references/tests/refusal.json - 8 test cases:
- Platform 2.3 manifest → Reject
whitelisted-domains→ Reject$request.post()→ Reject- Plain HTML buttons → Reject
- Missing
engines→ Reject - OAuth without
integrations→ Reject - Location in wrong module → Reject
- Missing Crayons CDN → Reject
Usage: Never generate these patterns.
Violation Tests (Common Mistakes)
references/tests/violations.json - 10 test cases:
- Async without await
- Unused parameters
- High complexity
- Variable scope issues
- Missing icon.svg
- Request not declared
- SMI function not declared
- OAuth missing options
- Missing alwaysApply in rules
- Missing product module
Usage: Check generated code against these violations.

Constraints (Enforced Automatically)
- Strict mode: Always reject Platform 2.x patterns
- No inference without source: If not in references, respond "Insufficient platform certainty"
- Terminal logs backend only:
console.logonly inserver/server.js, not frontend - Production-ready only: Generate complete, deployable apps
- Forbidden patterns: Listed in refusal tests
- Required patterns: Listed in golden tests
Serverless Events Reference
For complete event list by product:
- Load:
references/events/event-reference.md
Key events:
onAppInstall(MUST include if app uses iparams)onAppUninstall(MUST include if app has scheduled events/webhooks)onTicketCreate,onTicketUpdate(in product modules)- Scheduled events created dynamically with
$schedule.create()- NOT declared in manifest
Request Templates & OAuth
For detailed request template syntax and OAuth configuration:
- Load:
references/architecture/request-templates-latest.md - Load:
references/architecture/oauth-configuration-latest.md - Load:
references/api/request-method-docs.md
Quick Rules:
- Host must be FQDN only (no path)
- Path must start with
/ - Use
<%= context.variable %>for iparams - Use
<%= access_token %>for OAuth - OAuth requests need
"options": { "oauth": "integration_name" }
Jobs Feature
For Jobs documentation:
- Load:
references/runtime/jobs-docs.md
Quick pattern:
- Declare in manifest:
modules.common.jobs.jobName - Invoke from frontend:
client.jobs.invoke("jobName", "tag", {data}) - Handle in server:
exports.jobName = async function(args) { ... }
