Use secure OAuth 2.0 tokens issued by GHL for the Contacts API with the scope contacts.readonly.
Authorize the Zapier App Connector to access GHL data using OAuth 2.0 client credentials and token refresh for ongoing automation.

Glossary of terms and core processes used in the integration
A record for an individual in your GHL Contacts database
A unit of work related to a contact, such as a call or to-do
A URL path and HTTP method used to access data in the GHL API
The process of proving identity to access APIs, typically OAuth 2.0
Automatically create or update a contact when a form is submitted
Create tasks in your PM when a contact field changes
Attach notes to contacts automatically as events occur
Grant access and set scopes for the Contacts API
Choose which contact fields flow between GHL and your apps
Create triggers and actions to automate workflows
No-code is not required. The Zapier App Connector provides a visual, drag-and-drop interface to configure triggers, actions, and data mappings. You can automate most workflows without writing code. For advanced needs, you can still customize steps using built-in fields and filters. To start, connect your GHL account to Zapier, choose the Contacts API, and select the endpoints you want to use. Then build your automation with simple if/then logic and test in real time.
Authentication is handled via OAuth 2.0. You will authorize the Zapier App Connector to access your GHL data, which will provide access tokens scoped to your needs (e.g., contacts.readonly). Renewal happens automatically behind the scenes. If you need to re-authenticate, you can re-run the OAuth flow from the app’s connections page and refresh tokens as needed.
Rate limits depend on your GHL plan and the endpoint being used. Typical limits are designed to prevent abuse while enabling reliable syncing. If you hit a limit, Zapier will queue requests or retry after a cooldown period.
Yes. The Contacts API supports creating, updating, and deleting contacts. In Zapier, configure POST, PUT, and DELETE actions to manage contacts directly from your automations.
You can work with tasks, notes, and tags. Endpoints exist for tasks, notes, and tagging contacts, enabling complete workflow automation across apps.
Use the built-in test tool in the Zapier app to run a test with sample data and verify that triggers fire and actions execute as expected. You can also test individual endpoints directly to ensure data is returned correctly.
API endpoints are listed in the Endpoint list section above. You can also refer to the GHL API documentation for details on parameters, responses, and error codes.
Due to high volume, we will be upgrading our server soon!
