Requests to the Contacts API use OAuth 2.0 tokens scoped to readonly. Manage credentials and token refresh via the Zapier connector.
Zapier securely stores and refreshes credentials. After you authorize, the connector can access Contacts data within the defined scope.

Zapier trigger: Retrieve a particular task by ID
Actions: Get task details, mark as completed, update notes
GET /contacts/:contactId/tasks/:taskId
contactId, taskId
Automation without custom coding saves time and reduces errors
Consistent data flow across apps like CRMs, sheets, and calendars
Rapid prototyping with ready-made endpoints and templates
Key elements include endpoints (what you call), triggers (when to run), actions (what happens), methods (HTTP verbs), and fields (data points).
A specific URL and HTTP method used to access a resource in the GHL Contacts API.
A person record stored in your GHL CRM with associated data like tasks, notes, and appointments.
A text item attached to a contact, such as comments or meeting notes.
A to-do item linked to a contact, used to track follow-ups and activities.
Use a Zap to push sheet edits to contact records in GHL via the Contacts API.
Automatically generate tasks when a new lead is captured, keeping teams aligned.
Append submission content as notes on the related contact for context and history.
Register the Contacts API in the GHL developer console and set the scope to readonly.
Run the OAuth flow in Zapier to grant access to Contacts data.
Test zaps for triggers and actions, then deploy for production use.
The Contacts API in this integration uses OAuth 2.0 and is scoped to readonly, meaning you can read contact data but cannot modify it from Zapier. To enable write access, adjust the scope to contacts.write in your app registry and reauthorize the connection. This ensures you can perform actions that create or update data if your use case requires it. Two-factor: When ready, retry with the expanded permissions.
Write capabilities depend on scope and endpoint permissions. With readonly scope, you can still chain read endpoints to populate dashboards and reports. If your workflow needs to create or update contacts, switch to a write-enabled scope and use endpoints like POST, PUT, and DELETE as appropriate. Always test in a staging environment first.
Looker supports a range of endpoints for contacts, tasks, notes, and appointments. Begin with GET /contacts/:contactId to fetch a contact, then explore nested endpoints for tasks and notes. The endpoint list above shows all available calls. Use the IDs you need (contactId, taskId) to map data in Zapier.
In Zapier, enable the Looker app, connect your GHL account, and use the built-in test feature to verify responses. Create sample Zaps that trigger on retrievals and execute actions to confirm data mapping. Validate payload fields and error handling in your test runs.
Most lookups require a contactId as a path parameter. Some tasks or notes will require a taskId or note id. If you don’t have an ID handy, start with GET /contacts/:contactId to enumerate the contact’s data and locate related IDs for subsequent requests.
Official docs live in your GHL API reference and the Zapier Looker app page. Review endpoint paths, parameter names, and response formats. The glossary section in this wiki is a helpful quick reference for terms like endpoints, triggers, and actions.
OAuth tokens expire and should be refreshed automatically by the connector. If you see authentication errors, re-authenticate the Zapier app to obtain a fresh access token, and ensure your refresh token is valid. Keep scopes aligned with requested permissions.
Due to high volume, we will be upgrading our server soon!
