Authorize Zapier App Connector to access Contacts API with the required scope (contacts.readonly). Use OAuth or an API key as provided by your backend.
In Zapier, establish a secure connection by supplying the app credentials and access token, then test access to the Contacts API 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
Trigger: when a contact is updated in GHL
Actions: create or update a record in your app, pull /contacts/:contactId and /contacts/:contactId/tasks
GET /contacts/:contactId, GET /contacts/:contactId/tasks
Key fields: contactId, taskId
Trigger: new note added to a contact
Actions: append notes to records, create notes in app from /contacts/:contactId/notes
GET /contacts/:contactId/notes
contactId, id
Trigger: task updated or completed in GHL
Actions: update task status in connected app, mark as completed via /contacts/:contactId/tasks/:taskId/completed
PUT /contacts/:contactId/tasks/:taskId, PUT /contacts/:contactId/tasks/:taskId/completed
contactId, taskId
No-code automation between Contacts API and Zapier App Connector
Rapid connection setup with pre-built triggers and actions
Low maintenance with centralized data flow and error handling
Key elements include endpoints, triggers, actions, methods, and data fields used to connect GHL Contacts API with Zapier App Connector.
A specific URL and HTTP method used to access a resource, for example GET /contacts/:contactId.
A secure authorization framework that allows Zapier App Connector to access GHL data without sharing credentials.
A real-time, event-driven notification mechanism between GHL and Zapier.
An individual in your CRM whose data can be read or updated via the Contacts API.
When a form is submitted, Zapier creates or updates a Contacts API contact and attaches related tasks for follow-up.
Notes from contacts endpoint are logged into your CRM notes area or knowledge base for context.
Create and update tasks via API as new submissions arrive, with status updates tracked automatically.
Register application access to the Contacts API, obtain client credentials, and grant scope contacts.readonly.
In Zapier, add a new connection for the Zapier App Connector and supply the credentials and endpoint base URL.
Run test triggers, verify data mapping for contactId, tasks, notes, and publish to production.
Yes. You typically need admin or developer access to set up an OAuth app or API key with Contacts API. After registering your app, you’ll receive client credentials and a client secret. Use these to authorize the Zapier App Connector and request the required scope, such as contacts.readonly. If you don’t have access, contact your GHL admin to enable API access.
Essential endpoints often include GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks to retrieve tasks, and GET /contacts/:contactId/notes to access notes. POST /contacts/ might be used to create new contacts, while PUT /contacts/:contactId updates existing records.
Authentication typically uses OAuth for user-based access or an API key for service-to-service connections. In Zapier, you’ll configure a connection that stores the token or key securely and maps credentials to the Contacts API base URL. Regularly refresh tokens as required by your OAuth provider.
Yes. Zapier actions can create or update tasks and notes on a contact. Use the endpoints for creating tasks (POST /contacts/:contactId/tasks) and updating task status (PUT /contacts/:contactId/tasks/:taskId) to reflect form-driven work.
Map fields such as contactId, firstName, lastName, email, and phone for contacts. For tasks, map taskId, title, dueDate, and status. For notes, map noteId and content. Consistent field naming helps maintain data integrity across apps.
Security is ensured by using OAuth or API keys, encrypted storage in Zapier, and least-privilege scopes. Regularly rotate credentials and monitor access logs. Use HTTPS for all API calls and validate responses in your Zapier workflows.
Common issues include invalid credentials, insufficient scopes, or endpoint changes. Verify the connected account, reauthorize if needed, check the exact endpoint path, and review the API response for error messages. Test each step individually in Zapier.
Due to high volume, we will be upgrading our server soon!
