Authenticate to the GHL Contacts API using OAuth 2.0 with a scope of contacts.readonly to safely retrieve data without making changes.
Connect Zapier App Connector to your GHL account by providing credentials and granting the requested permissions for the Contacts API.

Trigger on new notes or new appointments for a contact.
Actions: Read notes and appointments, then push data to your system.
GET /contacts/:contactId/notes; GET /contacts/:contactId/appointments
contactId, noteId, appointmentId
Trigger when a new contact is created in GHL or a task is created.
Actions: POST /contacts/, POST /contacts/:contactId/tasks, PUT /contacts/:contactId, PUT /contacts/:contactId/tasks/:taskId
POST /contacts/; POST /contacts/:contactId/tasks; PUT /contacts/:contactId; PUT /contacts/:contactId/tasks/:taskId

Build end-to-end automation with a no-code interface in Zapier App Connector.
Scale workflows quickly across teams without custom development.
Keep contact data in sync, reduce manual updates, and improve data quality.
Learn the core concepts: API endpoints, authentication, scopes, and data objects involved in the GHL Contacts API and Zapier App Connector.
A specific URL path in the GHL API that performs an action such as retrieving a contact or creating a task.
The process of granting access to a resource, typically via OAuth 2.0 with tokens and scopes.
A standard protocol used to obtain limited access to user data without sharing credentials.
Permissions granted to an app (e.g., contacts.readonly) that define what data can be accessed or manipulated.
Trigger a welcome email, assign a task, and create a contact note when a new contact is added in GHL.
Aggregate weekly contact activity and send a summary to your team.
Trigger tasks and notes based on contact stage changes.
Authorize the GHL Contacts API in Zapier App Connector using OAuth 2.0 and select the contacts.readonly scope.
Pick the endpoints you need (read contacts, notes, tasks) and map fields to your app.
Create Zap workflows, test triggers and actions, and deploy to production.
No coding required. Use Zapier App Connector’s visual builder to connect GHL’s Contacts API. Choose triggers and actions, then map data fields to your app. The setup guides walk you through authorization and endpoint selection.
With contacts.readonly, you can fetch contact details, associated notes, tasks, and appointments. It prevents data changes while enabling robust reporting and automation.
OAuth 2.0 tokens are stored securely and refreshed automatically. Use best practices like token rotation and secure storage to protect access.
Yes. Use POST, PUT, and DELETE operations where supported to create, update, or remove contacts, tasks, and notes through Zapier workflows.
Endpoints like GET /contacts/:contactId, GET /contacts/:contactId/tasks, and GET /contacts/:contactId/notes are ideal for read-heavy automations and reporting.
Test with Zapier’s built-in test tools and sandbox environments. Validate each trigger and action, then run a few end-to-end scenarios.
Check API documentation for rate limits, quotas, and retry behavior. Plan backoff strategies in your Zapier workflows.
Due to high volume, we will be upgrading our server soon!
