Use OAuth 2.0 or API keys as provided by GHL to securely authorize your integration.
Connect Zapier to your GHL account by granting permissions for the Contacts API scope.
GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/tasks/:taskId; GET /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id; GET /contacts/:contactId/appointments; GET /contacts/; GET /contacts/business/:businessId; POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/tags
Use GET /contacts/:contactId and related GET calls to trigger automations when contact data changes.
No write actions are required for this pattern; ideal for monitoring, reporting, and alerting.
GET /contacts/:contactId
Key fields: contactId, lastName, email, phone
Create or update tasks and notes in GHL when Zapier events fire.
POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; POST /contacts/:contactId/notes; PUT /contacts/:contactId/notes/:id
POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId
Fields: contactId, taskId, title, status, dueDate, notes
Synchronize large sets of contacts and tags between GHL and Zapier.
POST /contacts/ to add, POST /contacts/:contactId/tags to tag, PUT /contacts/:contactId to update
GET /contacts/ and POST /contacts/ for creates
Fields: contactId, businessId, tags
Automate repetitive workflows without writing code.
Ensure data consistency across apps in real time.
Access Contacts, Tasks, and Notes from a single automation layer.
Definitions of key terms and the processes used to integrate the GHL Contacts API with Zapier.
A specific URL path used to access a resource in an API.
Verifying identity and granting access to a service.
A callback over HTTP to deliver real-time data.
An authorization framework that lets applications access user data securely.
When a form fills in a lead, automatically create or update a contact in GHL and trigger follow-up tasks.
Link support tickets to contact tasks to streamline issue tracking.
Automatically tag contacts based on events and segment by behavior.
Grant access to the Contacts API in your GHL account or connect via OAuth.
Choose the Contacts API as the resource and authorize mapping.
Map fields between GHL and Zapier and run test automations.
The integration uses the Contacts API with a readonly scope by default (Scope: contacts.readonly). This allows Zapier to fetch contact data, tasks, notes, and appointments for automation and reporting. If you need to write or modify data in GHL from Zapier, you would enable additional scopes or use dedicated endpoints that permit writes, such as POST/PUT/DELETE operations listed in the endpoint list.
Yes. You can create and update contacts using endpoints like POST /contacts/ and PUT /contacts/:contactId, as well as manage tasks and notes with POST/PUT calls. In Zapier, you map fields accordingly and set up actions to create or modify data in GHL when triggers fire.
The available endpoints include reading contacts, tasks, notes, appointments, and business data, plus writing endpoints to create, update, delete, or tag records. See the endpoint list above for the complete set: GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/:contactId/tasks, etc.
Authentication is typically performed via OAuth 2.0 or API keys provided by GHL. In Zapier, you authorize the connection once, then your workflows can call the endpoints. Ensure you grant the Contacts API scope and test the connection to confirm accessible resources.
No heavy coding is required. The Zapier App Connector provides a no-code interface to map triggers, actions, and fields. You can configure authenticated connections and use built-in actions to interact with GHL data.
Bulk operations aren’t exposed as a single batch endpoint in the listed API. You can simulate bulk behavior by chaining multiple actions or by designing a Zap with iterative steps. For large migrations, consider chunking data and using pagination with GET calls to manage limits.
Errors from GHL endpoints surface in Zapier with status codes and messages. Verify authentication, permissions, and input field mappings. Retry policies, rate limit handling, and detailed error messages help diagnose and fix issues quickly.
Due to high volume, we will be upgrading our server soon!
