Authenticate with OAuth 2.0 using the Contacts API scope: contacts.readonly. Use the standard OAuth flow to obtain access tokens and refresh tokens.
Zapier App Connector authentication relies on OAuth 2.0 client credentials or an API key, depending on your setup; securely store credentials and rotate them regularly.
Available endpoints: GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/tasks/:taskId; GET /contacts/:contactId/notes; GET /contacts/:contactId/notes/:id; GET /contacts/:contactId/appointments; GET /contacts/; GET /contacts/business/:businessId; 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

Automate data sync between GHL and your app without writing code.
Build multi-step workflows that react to changes in contacts, tasks, notes, and appointments.
Create reusable automations that scale across teams and departments.
A quick glossary of terms and core concepts for the GHL Contacts API integration with Zapier App Connector.
OAuth 2.0 is a standard protocol for authorizing access to APIs without sharing user credentials.
An API path that performs a specific operation, such as retrieving a contact or a task.
Granular permissions granted to access resources in an API.
A URL that receives event notifications from the API when something changes.
Route contacts to different workflows based on attributes like status or tier to automate follow-ups.
Aggregate contact tasks from multiple endpoints into a single view in your app.
Use notes to trigger quality checks or reminders for contacts.
Create an OAuth client in the Contacts API and authorize the connection from Zapier App Connector.
Map the endpoints you’ll use (contacts, tasks, notes, appointments) to Zapier steps.
Test data flows, validate auth, and deploy to production.
The integration uses the Contacts API scope: contacts.readonly to retrieve contact data without allowing write access. For most workflows, this is sufficient. You can request broader scopes if your app needs write capabilities, but keep security in mind and only grant what’s necessary. Ensure tokens are stored securely and refreshed before they expire.
For basic syncing you typically need GET endpoints such as GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments. Also include GET /contacts/ to list contacts if needed. Use POST/PUT/DELETE sparingly and with explicit user actions.
Authenticate using OAuth 2.0 with the Contacts API and your APPNAME client. In Zapier App Connector, configure the OAuth flow with the Client ID, Client Secret, and Redirect URI. Tokens are stored securely and refreshed automatically.
Yes. Webhooks or polling can trigger actions when a contact changes in GHL. Set up a Trigger in Zapier that responds to the endpoint events you subscribe to, such as contact updates or new notes, and route them into your workflow.
No-code is possible with Zapier App Connector. You can create powerful automations using triggers, actions, and filters without writing code. For advanced needs, you can extend with custom scripting if your plan allows.
Tokens expire and must be refreshed. Implement token refresh in the OAuth flow and handle 401 responses gracefully to re-authenticate without interrupting user workflows.
Check API rate limits in the provider’s docs. Plan for throttling, batch requests when possible, and implement exponential backoff to stay within limits.
Due to high volume, we will be upgrading our server soon!
