Authenticate using your GHL credentials and grant read-only access to Contacts data, then configure the Zapier App Connector to use the API key or OAuth token.
Authorize the app to access your Contacts data and specify the data scopes required (contacts.readonly) for syncing and automation.
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 contacts.write 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

POST /contacts/ to create, PUT /contacts/:contactId to update
Key fields: email (required), firstName, lastName, phone, businessId, tags, notes
Trigger: on contact changes, pull related tasks and notes via GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes
Actions: fetch tasks and notes, create or update records in app, trigger downstream workflows
GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes
Fields used: contactId, taskId, noteId, content, status
Trigger: when a contact’s appointment is scheduled or updated

Flexible triggers and actions for complex workflows
This glossary defines endpoints, triggers, actions, and data mapping concepts used when integrating the GHL Contacts API with the Zapier App Connector.
A specific URL and HTTP method used to access a resource in the API.
How fields from GHL map to fields in your app during syncs and transfers.
The process of granting the app permission to access GHL data, typically via OAuth or API keys.
A real-time push notification sent from GHL to your app when data changes.
Automatically create or update contacts from forms into GHL and kick off follow-up tasks.
Sync tasks and notes when a contact changes to keep teammates aligned.
Bring business data and appointments into your automations for richer workflows.
Grant access to the Contacts API in your Zapier App Connector settings.
Define which contact changes should trigger workflows and what data to pull.
Map GHL fields to your app fields and run end-to-end tests.
You typically need read permissions for contacts, and in some cases write permissions if you plan to create or modify data. The Scope provided (contacts.readonly) limits actions to reading; for write operations ensure the appropriate scope is granted.
Yes. The API supports creating and updating contacts, tasks, and notes via the endpoints. Deletion and full data management require proper permissions.
Use the endpoint list to test with tools like Postman or curl. Validate responses, handle errors, and ensure correct authentication.
Some endpoints may require a businessId to scope results to a particular business. Check endpoint docs to confirm.
API rate limits apply. Plan your calls and use batching where possible; implement retries with backoff.
Pagination is handled via query params or response fields; follow the API’s pagination guidance to fetch all records.
Webhooks are supported to push updates from GHL to apps; configure webhooks in GHL and in Zapier to trigger automations.
Due to high volume, we will be upgrading our server soon!
