Access to the Contacts API is secured with OAuth tokens and scope controls. Ensure you have approved access for contacts read only and the necessary endpoints before testing in Zapier.
Zapier handles OAuth in the OAuth2 flow and stores tokens securely. Your app will request permission to access the GHL Contacts API and obtain a token for API calls.

The GHL Contacts API is a programmatic interface that lets apps read create update and delete contact data. It enables you to build custom automations and integrations with your CRM. This API exposes endpoints to manage contacts tasks notes and more. By using the API you can sync data across systems in real time.
No coding is required if you use the Zapier App Connector. The connector provides a no code bridge to map fields and trigger actions. Some basic configuration within Zapier is needed and you may reference endpoints for field mapping but you do not need to write code.
The available endpoints cover contacts creation updates deletion and related resources such as tasks notes and appointments. Core endpoints include GET /contacts/:contactId POST /contacts PUT /contacts/:contactId and DELETE /contacts/:contactId along with task and note endpoints for full workflow automation.
Authentication uses OAuth tokens and scopes to grant access to the Contacts API. In Zapier you will configure an OAuth connection the app will request the appropriate scopes and you will authorize the connection before sending API requests.
Yes you can automate notes tasks and appointments. You can create tasks assign them to contacts add notes and attach related information as part of your Zapier workflows.
If an error occurs you can review API responses in Zapier test mode check for invalid fields and review logs. Implement retries and clear mappings to ensure data integrity.
Endpoint details appear in the API reference section of this guide and in the GHL API docs. You can also view the endpoint list above which shows method paths and typical use cases and parameters.
Due to high volume, we will be upgrading our server soon!
