Authenticate using OAuth 2.0 with your GHL credentials to authorize access to the Contacts API, and configure the Zapier App Connector to securely manage tokens within the workflow.
In Zapier, store and rotate your GHL access tokens securely, using the built-in OAuth flow and refresh tokens to maintain a live connection.
Endpoints include reading a contact and its related data (GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/:contactId/appointments), listing all contacts (GET /contacts/), and read/write operations for contacts and tasks (POST /contacts/, PUT /contacts/:contactId, DELETE /contacts/:contactId, POST /contacts/:contactId/tasks, PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed, DELETE /contacts/:contactId/tasks/:taskId, POST /contacts/:contactId/tags). A full set of endpoints for business data (GET /contacts/business/:businessId) is also available.

contactId, id
Trigger: Bulk sync started or on a schedule
POST /contacts/; PUT /contacts/:contactId; DELETE /contacts/:contactId; POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId

Automate CRM updates without writing code.
Leverage real-time data from GHL in your Zapier workflows.
Rapid deployment with endpoint-driven triggers and actions.
This glossary defines common terms, including API, Endpoint, OAuth, and Authentication, and explains how they apply to connecting GHL’s Contacts API with Zapier.
Application Programming Interface that lets apps communicate.
A specific URL and HTTP method used to perform an action in an API.
Open standard for access delegation used to grant secure access to resources without sharing credentials.
Process of verifying identity and granting access rights.
Set up a workflow that updates contact records automatically when a GHL event occurs (new contact, updated contact, etc.).
Create tasks in your project management app whenever a GHL task is created or updated.
Trigger alerts or summaries when notes are added or updated for a contact.
Get client ID, client secret, and refresh tokens; configure in Zapier.
Set up authentication, triggers, actions, and test connection.
Launch the integration and monitor for errors or rate limits.
The Contacts API scope used in this guide is contacts.readonly, which allows reading contact data and related resources but not modifying them. For write operations, you’ll need write permissions and proper authorization. Ensure you comply with data access policies.
Authentication is handled via OAuth 2.0. In GHL, you set up OAuth credentials, then connect them to the Zapier App Connector, which securely stores tokens and refreshes them as needed.
Read endpoints include: GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, GET /contacts/, GET /contacts/business/:businessId. You can also read lists like /contacts and related items.
Yes. The API includes endpoints for updating and creating contacts and their related resources, such as POST /contacts/ and PUT /contacts/:contactId. You can also manage tasks or notes via dedicated endpoints.
No coding is required if you use the Zapier App Connector; you can configure triggers and actions through the UI.
To test the connection, use the Test Connection button in Zapier’s app setup, then run a sample task to verify data flow.
Rate limits are defined by GHL. Refer to GHL API docs for exact quotas; monitor usage via your app’s dashboard.
Due to high volume, we will be upgrading our server soon!
