Access to the Contacts API via the Zapier App Connector requires a secure credential. Use an API key or OAuth depending on endpoint support. Store keys securely and rotate as needed.
In Zapier, create a connection for the Contacts API, choosing OAuth 2.0 if supported or an API key method. Grant minimal scopes and test the connection.

No coding is required. Zapier provides triggers, actions, and connectors that map GHL Contacts API endpoints to your workflows. You can set up automations with a few clicks. If you need more complex logic, you can always introduce small code steps, but it’s not required. The content is designed to be accessible for non-developers.
You can use endpoints for retrieving and managing contacts, tasks, notes, and appointments. Not all endpoints will be needed for every page, but the main ones include GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/, PUT /contacts/:contactId, and DELETE /contacts/:contactId.
Authentication is handled via API keys or OAuth, depending on the endpoint. In Zapier, you’ll configure a connection and securely store credentials, then the app will pass tokens with each request.
Yes. Endpoints for tasks and notes expose data for each contact. You can pull lists of tasks or notes or retrieve individual items. Use the appropriate trigger to keep data in sync.
Yes. Create contacts by using POST /contacts/ and assign necessary fields. Ensure you have permission to write contacts in your account.
Rate limits vary by plan and API usage. If you hit a limit, implement exponential backoff and stagger requests. Review your plan’s quotas in your developer console.
Endpoint documentation is available in the API reference for the Contacts API. Use the list of endpoints above as a quick start and consult the official docs for details on parameters and responses.
Due to high volume, we will be upgrading our server soon!
