Use OAuth with your GHL account to authorize the Contacts API access via the Zapier App Connector. Ensure your API key or token has the scope: contacts.readonly.
In Zapier, connect the Zapier App Connector to your GHL account by selecting the Contacts API then authorize with your GHL credentials. This grants read only access per the scope.
Endpoints covered include 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

Fast setup with no coding required
Automate routines across contacts notes and tasks
Scale CRM processes with built in triggers and actions
This glossary covers API endpoints authentication requests responses and common terms to help you navigate the integration
A specific path in an API that performs a defined action such as GET /contacts/:contactId
The process of verifying identity and granting access tokens to call the API
A cap on the number of API requests within a time window to prevent abuse
A callback mechanism that notifies your app when a specific event occurs
Trigger: contact milestone; Action: create a follow up task via POST /contacts/:contactId/tasks
Trigger: new note on a contact; Action: post to notes in CRM
Trigger: contact updated; Action: add tags via POST /contacts/:contactId/tags
In Zapier authorize the Zapier App Connector to access your GHL account and select the Contacts API
Choose a trigger such as contact updated and map actions using the endpoints
Run tests in Zapier to ensure endpoints respond as expected then enable in automation
No coding is required with the Zapier App Connector. Use the visual UI to configure triggers and actions and test them in seconds. For more complex flows you can layer multiple steps and utilize built in filters. You can still extend with simple logic if needed.
By default the scope shown for this integration is readonly, which enables read operations only. If your project requires write access you can request broader permissions and use endpoints like POST PUT and DELETE under proper governance.
Yes you can write data when you have the appropriate write scope. Endpoints such as POST and PUT let you create and update contacts tasks and notes. Always test changes in a safe environment before enabling live automations.
Authentication typically uses OAuth for secure access to the GHL Contacts API via the Zapier App Connector. The Zapier app will securely store tokens and refresh them as needed.
Test endpoints directly in Zapier using the built in test feature or run manual requests in a staging environment. Validate responses ensure status codes are expected and verify data mapping.
Implement retries with exponential backoff handle rate limits 429 errors and log failures. Use idempotent requests where supported and monitor automation performance to adjust thresholds.
Endpoint references are shown in the Endpoints section of this page and in the developer documentation for the Contacts API. You can also copy endpoint paths from your Zapier configuration when building your workflow.
Due to high volume, we will be upgrading our server soon!
