To access Contacts API, obtain an OAuth 2.0 access token with the scope ‘contacts.readonly’. Use the token to authorize requests and keep it secure.
In Zapier, create a new connection to the Contacts API, paste your OAuth client credentials, and authorize Zapier to perform actions on your behalf.
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; API Scope: 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

Select endpoints and map fields to your target apps.
Run tests, verify data flow, and enable automation in production.
No coding is required. Zapier App Connector provides a no-code interface to map GHL Contacts API fields to your apps. You configure triggers and actions, then run tests to ensure data flows as expected. If you’re familiar with forms and automations, you’ll be up and running quickly. The combination of the Contacts API and Zapier enables powerful workflows without writing code.
The Contacts API uses OAuth 2.0 tokens with a scope of ‘contacts.readonly’ for read access. For actions that modify data, you’ll obtain the appropriate permissions (e.g., write scope). In Zapier, you’ll create a connection and securely store these credentials for ongoing use. Always rotate tokens and follow best security practices.
Available endpoints include: 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, plus write and create endpoints like POST /contacts/, POST /contacts/:contactId/tasks, PUT /contacts/:contactId, and DELETE /contacts/:contactId. This set covers typical contact, task, and note workflows.
Yes. Zapier can create or update contacts via endpoints like POST /contacts/ and PUT /contacts/:contactId. You can map fields from one app to the Contacts API fields, enabling seamless data synchronization across your tech stack. Ensure you have the write scope enabled for endpoints that modify data.
In Zapier, use the Test action to verify that authentication succeeds and that the trigger or action pulls or pushes the expected fields. You can also simulate API responses to confirm field mappings. After testing, deploy the workflow to production with monitoring in place.
Automation can run in near real-time depending on the trigger. Webhooks are not required; Zapier polls or uses app-provided triggers to sync data. For critical updates, you can design multi-step workflows to ensure prompt data synchronization.
The endpoint list and schema are documented in the integration guide within the Zapier App Connector and the Contacts API documentation. You’ll find detailed descriptions of each endpoint, required parameters, and the data models for contacts, tasks, notes, and appointments.
Due to high volume, we will be upgrading our server soon!
