Access to the Contacts API from Zapier uses OAuth 2.0 with the scope: contacts.readonly. Authorize your GHL account to enable requests from the Zapier App Connector.
Zapier handles authentication via OAuth 2.0 tokens and refresh flows. Ensure your app credentials are configured securely and that the connection is authorized before running automations.
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
Trigger: New or updated contact is detected in the GHL Contacts API.
Actions: Retrieve contact data with GET /contacts/:contactId and fetch related tasks with GET /contacts/:contactId/tasks.
GET /contacts/:contactId and GET /contacts/:contactId/tasks
contactId, name, email, phone, taskId for tasks retrieval
Trigger: Updated contact prompts task creation in your workflow.
POST /contacts/:contactId/tasks
contactId, taskTitle, dueDate, priority
Trigger: Contact data changes in GHL.
PUT /contacts/:contactId and POST /contacts/:contactId/tags
contactId, status, tags
No-code automation lets you connect your data without writing code, reducing manual entry.
Fast, trigger-based workflows run in real time to keep systems in sync.
Reusable connections scale across teams and apps with minimal maintenance.
This section explains core elements like endpoints, authentication, data mapping, rate limits, error handling, and testing to ensure reliable integrations.
A specific URL path in an API that performs a defined action, such as retrieving a contact or updating a task.
The mechanism that verifies identity and grants access, typically OAuth 2.0 in this integration.
An authorization framework that issues access tokens to clients to call APIs securely.
Permissions granted to an app to access specific resources in the API.
Set up a Zap to generate a new task in your project management tool whenever a contact’s status changes.
Automatically push contact details to your CRM or email platform when a new contact is added.
Whenever a support ticket is opened, append a note to the related contact with the ticket summary.
Choose a trigger like ‘New or Updated Contact’ and connect your GHL account.
Map fields and set up actions such as creating tasks or updating contact data.
Run tests to verify data flow and then enable the Zap.
The Contacts API uses OAuth 2.0 with the required scope configured for your Zapier App Connector connection. This ensures only permitted data is accessible. Always review the scope before enabling automations. You can request broader permissions if your integration needs to write or modify data, but this page focuses on read-only access to keep things secure.
Authentication is managed via OAuth 2.0 in both the GHL side and the Zapier App Connector. You’ll authorize your GHL account once, and Zapier will handle token refreshes automatically. If your token expires, reauthorize from the connected accounts area.
The available endpoints cover reading contacts, their tasks, notes, and basic management actions like creating or updating records. See the endpoint list for the full set of supported paths.
Yes. The Contacts API supports write operations such as POST /contacts/ to create new contacts and POST /contacts/:contactId/tasks to add tasks. Write permissions require appropriate scope and authorization.
Rate limits depend on your GHL plan and the API’s policy. If you hit a limit, you’ll receive an error and can design retries in Zapier with exponential backoff. Monitor API responses to stay within the allowed quotas.
Field mapping is done in Zapier at the action step. Map source fields from the trigger to destination fields in your app, and sample data helps you verify accuracy during test.
Due to high volume, we will be upgrading our server soon!
