Use OAuth credentials issued by GHL for the Contacts API and configure in Zapier under the Contacts API app. Start with readonly scope to view data, then expand as needed.
Authorize Zapier App Connector to access Contacts data. Grant requested scopes and test the connection from the Test Connection button.

Easily scale integrations with reusable components in Zapier
This section defines endpoints, authentication, triggers, and data fields used to connect GHL Contacts API with the Zapier App Connector.
The process of granting and validating access to the Contacts API within Zapier.
A specific API URL that performs an action, such as retrieving a contact or a task.
A mechanism for real-time updates; not always required in this flow but supported where available.
Access level granted to the app, such as readonly, read/write.
Capture new leads in your system and push them into Contacts API in Zapier, then create related tasks automatically.
Whenever notes are added in your app, update the contact notes in GHL through the API.
Closing a task in the source system automatically marks it complete in Contacts API and updates the contact status.
Authorize the app to access Contacts data and generate credentials
Select endpoints like GET /contacts/:contactId and set scope to readonly
Run tests to verify data flow and deploy to production
To connect the GHL Contacts API with Zapier App Connector, create a new connection in Zapier, select Contacts API, and enter your GHL OAuth credentials. Use the read-only scope initially to verify access and data retrieval. Once confirmed, you can request higher privileges if needed.
Scope should include readonly for initial reads. If updates are required, switch to read/write. Ensure the GHL app has the correct permissions and that you re-authenticate after changing scopes.
Primary read endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments, and GET /contacts/. You can also fetch business-level data with GET /contacts/business/:businessId. Use pagination where supported.
Yes. Use POST /contacts/ to create, PUT /contacts/:contactId to update, and POST /contacts/:contactId/tasks to create tasks. Ensure your OAuth scope allows write operations and test changes carefully.
In Zapier, click Test Connection after saving credentials. If it fails, verify client ID and secret, redirect URI, and that the correct scopes are granted. Check that the GHL app is configured to allow the Zapier app, and re-authenticate if needed.
API documentation is available in the GHL developer docs and the Zapier app connector docs. Refer to the endpoint references for parameters, required fields, and example requests.
Common issues include invalid credentials, insufficient scopes, and rate limits. Re-authenticate, confirm scopes, and implement retries in Zapier where appropriate. Review error codes returned by the API for targeted fixes.
Due to high volume, we will be upgrading our server soon!
