Use OAuth 2.0 with scopes like contacts.readonly to securely access contact data and associated records.
Zapier App Connector uses OAuth-based connections to securely link your GHL account and manage permissions for your automations.

Trigger on retrieving current contact data and related tasks using GET /contacts/:contactId and GET /contacts/:contactId/tasks for up-to-date information.
Actions include fetching contact details, pulling tasks, and reading notes with GET endpoints such as /contacts/:contactId, /contacts/:contactId/tasks, and /contacts/:contactId/notes.
GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/notes
Key fields: contactId, taskId, noteId, businessId
Trigger when a contact’s tasks or notes are updated via GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes.
Actions include creating tasks and notes with POST /contacts/:contactId/tasks and POST /contacts/:contactId/notes, and updating tasks with PUT /contacts/:contactId/tasks/:taskId.
GET /contacts/:contactId/tasks; POST /contacts/:contactId/tasks; GET /contacts/:contactId/notes; POST /contacts/:contactId/notes; PUT /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId, noteId, status
Trigger on changes to notes and business-related data via GET /contacts/:contactId/notes and GET /contacts/business/:businessId.
Actions include creating and retrieving notes via POST /contacts/:contactId/notes and reading business data via GET /contacts/business/:businessId.
GET /contacts/:contactId/notes; POST /contacts/:contactId/notes; GET /contacts/business/:businessId
Key fields: noteId, businessId, contactId
Automate data flow without writing code, reducing manual updates and errors.
Centralize contact data across apps for consistent customer views.
Easily scale automations as your business grows with configurable triggers and actions.
Understand endpoints, authentication, and data fields to design reliable automations with the GHL Contacts API and Zapier App Connector.
The GHL endpoint suite that lets you read and write contact data, tasks, notes, and more.
A specific URL path and HTTP method used to interact with GHL.
The process to verify identity and authorize API access, typically OAuth 2.0.
A method for receiving real-time data updates from the API via callbacks.
Capture form submissions and automatically create new contacts in GHL via POST /contacts/ to streamline onboarding.
When tasks are assigned in a PM app, create or update corresponding tasks in GHL using POST /contacts/:contactId/tasks and PUT /contacts/:contactId/tasks/:taskId.
Aggregate notes from multiple sources by posting notes to /contacts/:contactId/notes and syncing back to the appropriate records.
In GHL, authorize the Zapier App Connector and generate credentials for a secure connection.
Select required endpoints (read and write) and set the scope to contacts.readonly for safe access.
Test triggers and actions in Zapier, verify data flow, and deploy the integration to your workflows.
The Contacts API lets you read contact data, tasks, notes, and related records. You can also create new contacts and manage related items like tasks and notes. Practical use cases include syncing new leads, retrieving contact histories, and updating contact details. Ensure your OAuth scope is set to the minimum required for your automation to improve security. By combining reads with writes, you can build robust, no-code automations that reflect changes across connected apps.
Permissions are granted via OAuth connections. For read-only access choose scopes like contacts.readonly. If you need to create or update data, request write access (e.g., contacts.write). Always apply the principle of least privilege and review access periodically to maintain security.
No deep coding knowledge is required. Zapier App Connector provides no-code triggers and actions that map to GHL endpoints. You will configure connections, select endpoints, set fields, and test steps within the Zapier interface. Some basic understanding of API concepts helps, but templates and guides make setup approachable for non-developers.
Authentication uses OAuth 2.0. You’ll authorize the Zapier App Connector to access your GHL account, then grant permissions for the required scopes. After authorization, your connection token is stored securely and reused for automations. If tokens expire, refresh via the same flow.
Endpoints like GET /contacts/:contactId and POST /contacts/ are common for onboarding and lookup, while PUT /contacts/:contactId and POST /contacts/:contactId/tasks support updates and task management. Starts with a read-only setup to explore data, then add write endpoints as you build workflows.
Yes. The API supports updating existing contacts via PUT /contacts/:contactId, and updating tasks via PUT /contacts/:contactId/tasks/:taskId. Use careful validation to avoid overwriting important data, and test changes in a safe environment before deploying widely.
Use Zapier’s test feature to run through triggers and actions, verify data mappings, and confirm that updates reflect in GHL. Start with a sandbox or test contact, monitor logs, and then progressively move to production once the automation behaves as expected.
Due to high volume, we will be upgrading our server soon!
