Scopes configured for this integration include: contacts.readonly. You will authenticate requests using OAuth 2.0 tokens generated for your Zapier app.
To connect, create an OAuth credential in GHL for the Zapier App Connector and grant the necessary scopes (including contacts.readonly).
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
Trigger example: when a contact is created in your system, pull the contact details from GHL via GET /contacts/:contactId to start a workflow.
Possible actions: fetch contact data, then update notes or assign tasks in GHL via the corresponding endpoints.
GET /contacts/:contactId
Key fields: contactId, name, email, phone, company
Trigger: bulk sync triggers a pull of all contacts with GET /contacts/.
Actions: list contacts, filter by business or tags, then create/update related tasks.
GET /contacts/
Key fields: contactId, name, email, businessId
Trigger: when a task is due, use POST /contacts/:contactId/tasks to create tasks.
POST /contacts/:contactId/tasks
Key fields: contactId, taskId, title, dueDate, status
Build integrations quickly without coding; use Zapier as the connector.
Automate data flows between GHL and other apps like CloudTalk, CRM, or helpdesk.
Maintain a single source of truth with real-time data syncing across platforms.
This section defines API endpoints, authentication, data fields, and how to map responses into Zapier tasks.
A specific URL path in the API used to perform a function, such as retrieving a contact.
An authorization protocol that issues access tokens to call API resources securely.
A labeled permission that defines which endpoints and data can be accessed.
A data entity exposed by the API, such as contacts, tasks, notes, and appointments.
Automatically create a new GHL contact when a new lead is added in your CRM via Zapier, then tag and assign tasks.
When a contact is updated in your system, automatically create or update related tasks in GHL.
Sync notes and activities between CloudTalk and GHL to keep a complete contact history.
Create OAuth credentials in GHL for the Zapier App Connector and grant the necessary scopes.
In Zapier, select endpoints such as GET /contacts and GET /contacts/:contactId to pull data into your workflows.
Map API response fields to Zapier fields and run tests to ensure data flows correctly.
The GHL Contacts API lets you read contact data, tasks, notes, appointments, and related resources from GHL to power automations in Zapier. It enables building workflows that pull, filter, and display contact information in external apps. The API is designed to support data retrieval for reporting and automation scenarios. This page focuses on the contacts.readonly scope, which prioritizes safe read access for integration and analytics use cases.
Required permissions include the ‘contacts.readonly’ scope for read access. If you need to modify data (create/update), you must request additional scopes and ensure your app has those permissions granted. In Zapier, you define OAuth scopes during app setup and end users authorize those scopes during connection.
Authentication uses OAuth 2.0 tokens. Create OAuth credentials in GHL for the Zapier App Connector and exchange authorization codes for access tokens. Include the access token as a Bearer token in API calls and refresh tokens when needed. Keep tokens secure and rotate them according to your security policy.
Endpoints cover reading and managing contacts, tasks, notes, and appointments. Key examples include GET /contacts/:contactId and POST /contacts/ to create new contacts. You can also access related sub-resources like /contacts/:contactId/tasks and /contacts/:contactId/notes. Write endpoints such as PUT, PATCH, and DELETE exist for updating or removing data as required by the integration.
Yes. The Contacts API supports creating new contacts via POST /contacts/ and updating via PUT /contacts/:contactId. You can also create tasks and notes linked to a contact. Ensure your app has the necessary permissions and handles errors and rate limits gracefully. Use proper data validation and idempotency where appropriate to avoid duplicates.
Rate limits are defined by GHL and the OAuth plan in use. If you hit limits, implement retry with exponential backoff and consider batching requests where possible. Design your Zapier workflows to minimize unnecessary calls and cache non-changing data when feasible.
To test your connection, use the Zapier app’s test connection flow or make a simple GET request to an endpoint like /contacts/ to confirm access. Review the OAuth token status, check for permission prompts, and inspect API error messages for troubleshooting insights.
Due to high volume, we will be upgrading our server soon!
