The Contacts API uses a secure API key scoped to read access (scope: contacts.readonly). Include the token in the Authorization header when calling endpoints.
Zapier App Connector authenticates to the Contacts API via OAuth 2.0 client credentials or an API key. Configure the connection in Zapier and test it before automation.
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; contacts.write; 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

Fast setup with no code: build automations in minutes using triggers, actions, and filters.
Real-time data sync across apps ensures consistent contact details and task status.
Scalable workflows that grow with your business, with audit trails and error handling.
Understand core elements: endpoints, methods, triggers, actions, and key fields; see how data flows between GHL Contacts API and Zapier App Connector.
A specific URL path used to access a resource via the API (for example, GET /contacts/:contactId).
An event in one app that starts an automation in another app (for example, a new contact is created).
A task performed by an automation in response to a trigger (for example, create a contact or add a note).
The HTTP path used in an API request (for example, /contacts/:contactId).
Automatically create or update a contact in your CRM when a new user signs up, then assign onboarding tasks and schedule follow-ups.
When a ticket is created in your support system, update the contact notes in the Contacts API and trigger related actions.
Trigger automated follow-ups when a contact moves through your pipeline stages, sending reminders across tools.
Create a connection in Zapier for the Contacts API using your API key and OAuth credentials, then test the connection.
Choose the trigger (new or updated contact) and map actions to your other apps, including data fields and filters.
Run end-to-end tests, check error handling, and activate the automation for ongoing use.
Yes, the Contacts API supports read-only access in this integration scenario (scope: contacts.readonly). For write operations, use App credentials and appropriate scopes. If you need to write, request elevated permissions through your GHL admin and configure the Zapier App Connector connection accordingly.
Yes. You can create or update contacts, add notes, and manage tasks via the Zapier App Connector using the endpoints listed. Map fields carefully to ensure data integrity across apps.
The endpoint set includes GET endpoints to read contacts, tasks, notes, and business data. Use POST, PUT, and DELETE for creating, updating, and removing items as needed. Always verify permissions and scopes.
Use field mapping in Zapier to align source fields with destination fields (e.g., firstName -> first_name, email -> email_address). Use tests to confirm data flows correctly.
Yes, depending on your plan, there may be rate limits. Plan accordingly and implement batching or delay steps if needed; monitor quotas in your GHL account.
Check error messages in Zapier task history, verify authentication, and test individual actions. Use webhooks to troubleshoot and consult the endpoint docs for required fields.
We provide example templates and starter workflows in the Zapier App Connector gallery and in our documentation.
Due to high volume, we will be upgrading our server soon!
