Security Design

All API functions use pre-defined endpoint paths — there is no arbitrary HTTP request capability. Every user-supplied ID is validated against a strict alphanumeric regex (^[a-zA-Z0-9_-]{1,128}$) before being included in any URL path, preventing path traversal and injection. The scripts use only Python's built-in urllib.request for all network calls. No shell commands, no external binaries, no file writes outside of stdout.

Setup — /highlevel-setup

If the user says "set up highlevel", "connect my GHL", or /highlevel-setup, run the setup wizard:

python3 scripts/setup-wizard.py

The wizard automatically: checks environment variables → guides Private Integration creation → tests the connection → pulls first 5 contacts as a quick win.

Manual Setup (if wizard can't run)

Step 1: Create a Private Integration (NOT the old API Keys method)

1. Log into app.gohighlevel.com

2. Switch to your Sub-Account (recommended for single-location use)

3. Click Settings (bottom-left gear icon)

4. Select Private Integrations in the left sidebar

   • If not visible, enable it first: Settings → Labs → toggle Private Integrations ON

5. Click "Create new Integration"

6. Enter a name (e.g., "Claude AI Assistant") and description

7. Grant only the scopes you need (least-privilege recommended):

   Use case	Recommended scopes
   Contact management only	contacts.readonly, contacts.write
   Contacts + messaging	Above + conversations.readonly, conversations.write, conversations/message.write
   Full CRM (contacts, calendar, pipeline)	Above + calendars.readonly, calendars.write, opportunities.readonly, opportunities.write
   Adding workflows & invoices	Above + workflows.readonly, invoices.readonly, invoices.write
   Read-only reporting	contacts.readonly, opportunities.readonly, calendars.readonly, invoices.readonly, locations.readonly

   You can always add more scopes later in Settings → Private Integrations → Edit without regenerating the token.

8. Click Create → Copy the token IMMEDIATELY — it is shown only once and cannot be retrieved later

Agency vs Sub-Account Integrations

Recommendation: Start with a Sub-Account integration and the minimum scopes you need. You can upgrade to Agency-level later if you need multi-location access.

Step 2: Get Your Location ID

1. While in the sub-account, go to Settings → Business Info (or Business Profile)
2. The Location ID is displayed in the General Information section
3. Alternative: check the URL bar — it's the ID after /location/ in app.gohighlevel.com/v2/location/{LOCATION_ID}/...

Step 3: Set Environment Variables

export HIGHLEVEL_TOKEN="your-private-integration-token"
export HIGHLEVEL_LOCATION_ID="your-location-id"

Step 4: Test Connection

Run python3 scripts/ghl-api.py test_connection — should return location name and status.

After successful setup, pull 5 contacts as a quick win to confirm everything works.

Helper Script

scripts/ghl-api.py — Executable Python script (stdlib only) with built-in retry logic, pagination, input validation, and error handling.

Core Commands:

All functions are safe, pre-defined endpoints. No arbitrary request capability.

Complete API v2 Coverage (39 Endpoint Groups)

The skill provides safe, specific functions for all major GHL operations. Each function maps to a specific, allowed API endpoint with validated parameters.

Reference Docs (load on demand)

For detailed endpoint paths, parameters, and examples for each group:

• references/contacts.md — Contact CRUD, search, tags, notes, tasks, bulk operations
• references/conversations.md — Messaging across all channels, recordings, transcriptions
• references/calendars.md — Calendar CRUD, free slots, appointments, groups, resources
• references/opportunities.md — Pipeline management, stages, status updates
• references/invoices-payments.md — Invoices, payments, orders, subscriptions, products
• references/locations-users.md — Location settings, custom fields/values, users, tags
• references/social-media.md — Social planner posts, accounts, OAuth connections
• references/forms-surveys-funnels.md — Forms, surveys, funnels, trigger links
• references/advanced.md — Custom objects, associations, snapshots, SaaS, Voice AI, blogs, courses
• references/troubleshooting.md — Common errors, rate limits, token rotation, debugging

Important Notes

• Private Integrations are required — the old Settings → API Keys method is deprecated/EOL
• Token rotation: Tokens don't auto-expire but GHL recommends 90-day rotation. Unused tokens auto-expire after 90 days inactivity
  • "Rotate and expire later" — new token generated, old token stays active for 7-day grace period
  • "Rotate and expire now" — old token invalidated immediately (use for compromised credentials)
  • You can edit scopes without regenerating the token
• OAuth tokens (marketplace apps only): Access tokens expire in 24 hours (86,399s); refresh tokens last up to 1 year
• Agency tokens can access sub-account data by passing locationId parameter
• Rate limits are per-resource — each sub-account independently gets 100/10s burst + 200K/day. SaaS endpoints: 10 req/sec global
• All list endpoints default to 20 records, max 100 per page via limit param
• Use cursor pagination with startAfter / startAfterId for large datasets
• Monitor rate limits via response headers: X-RateLimit-Limit-Daily, X-RateLimit-Daily-Remaining, X-RateLimit-Max, X-RateLimit-Remaining, X-RateLimit-Interval-Milliseconds
• $497 Agency Pro plan required for: SaaS Configurator, Snapshots, full agency management APIs

Webhook Events

50+ webhook event types for real-time notifications. Key events: ContactCreate, ContactDelete, ContactTagUpdate, InboundMessage, OutboundMessage, OpportunityCreate, OpportunityStageUpdate, OpportunityStatusUpdate, appointment events, payment events, form submission events. Webhooks continue firing even if access token expires. Config is per marketplace app. Docs: https://marketplace.gohighlevel.com/docs/webhook/WebhookIntegrationGuide
