Access to the Contacts API is secured with your GHL credentials. Use the designated access token or OAuth client to authorize requests and ensure you have the proper scope: contacts.readonly.
In Zapier, connect the Zapier App Connector using OAuth 2.0 or an API key. Grant the permissions your workflow needs and test the connection.

This section defines core concepts and processes such as API endpoints, authentication, triggers, actions, and data fields.
Definition: The RESTful interface exposed by GHL to programmatically manage contacts, tasks, notes, and appointments.
Definition: An open standard for secure delegated access used to authorize apps without sharing credentials.
Definition: A URL and HTTP method that performs a specific operation on a resource.
Definition: The process of verifying identity before granting access to an API.
When a new lead is generated in your source, automatically create a contact in Contacts API and start associated tasks.
Map form fields to contact fields and keep data synchronized in real time.
Automatically create follow-up tasks or notes after an appointment to ensure consistent outreach.
Authorize access in GHL and connect the Zapier App Connector to obtain access tokens with the required scopes.
Select the endpoints you’ll read from and the events you’ll trigger to automate workflows.
Create Zapier zaps, map fields, and run tests to ensure data flows correctly.
The Contacts API is the GHL interface that lets you read and manage contacts, tasks, notes, and appointments. It enables programmatic access to core CRM data for building automated workflows. When paired with the Zapier App Connector, you can automate data flows without writing code. This makes it easy to keep records in sync across systems.
Authentication is done via OAuth2 or API tokens depending on your setup. In GHL, obtain access tokens from the developer console and grant the necessary scopes. In Zapier, connect the App Connector to exchange tokens securely. Always verify scopes such as contacts.readonly to limit access to what your workflow requires.
There are endpoints for reading contacts, tasks, notes, and appointments, as well as creating and updating them. The exact endpoints you use depend on your workflow. Not all endpoints are needed for every page, so pick the ones that match your use case.
Yes. Use POST /contacts/:contactId/tasks to create tasks; you can also create a contact via POST /contacts/. Zapier will trigger on create or update actions and perform related tasks automatically.
Yes. GET /contacts/:contactId/appointments can pull appointment data; you can create or update appointments via POST and PUT requests. This lets you keep scheduling in sync across apps.
Webhooks enable real-time triggers. You can configure Zapier to listen for GHL events via webhooks, then fire automated actions in your workflows.
Logs and errors can be viewed in Zapier task history and GHL API logs. Enable debug or verbose logging if needed to diagnose data mappings and authentication issues.
Due to high volume, we will be upgrading our server soon!
