Access to the Contacts API requires OAuth 2.0 credentials and securely stored tokens. Set up a GHL app and authorize scopes such as contacts.readonly.
Zapier handles OAuth 2.0 flows for the connected app and stores tokens securely, enabling automated tasks without exposing credentials.
Endpoints covered include: 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: Retrieve a single contact’s data to populate CRM fields or trigger downstream actions.
Actions: Read contact data to update tasks, notes, or follow-ups.
GET /contacts/:contactId
contactId, name, email, phone, company, tags, customFields
Trigger: When tasks for a contact change, you can pull task updates.
Actions: Create, update, or mark tasks as completed for a contact.
GET /contacts/:contactId/tasks
contactId, taskId, title, status, dueDate, assignee
Trigger: Retrieve details for a single task to drive automation.
Actions: Update task status, add notes, or reassign.
GET /contacts/:contactId/tasks/:taskId
contactId, taskId, status, title, dueDate, notes
Automate contact management and task workflows without writing code, using ready-made Zapier triggers and actions.
Speed up onboarding and data syncing between GHL and your tools with secure OAuth auth.
Scale automations across teams by reusing the same connection for multiple workflows.
Understand how endpoints, triggers, actions, and data fields come together to power no-code automations between GHL’s Contacts API and the Zapier App Connector.
A specific URL and method used to perform an operation in the API (e.g., GET /contacts/:contactId).
The process of proving identity to access protected resources, typically OAuth 2.0 in this integration.
An event that starts an automation or workflow when certain data changes.
An operation executed in response to a trigger, such as creating or updating a record.
Use the Get a Contact endpoint to fetch updated data when an email reply changes contact details, and push updates to CRM tasks.
When a new contact is added in GHL, automatically generate onboarding tasks via the Tasks endpoint.
Pull contact notes using the notes endpoint and store them in a centralized notes system for quick reference.
Register the Zapier App Connector in GHL and complete the OAuth 2.0 flow to grant access to Contacts data.
Select the required endpoints (e.g., GET /contacts/:contactId) and map GHL fields to Zapier fields for your workflows.
Create Zapier automations, test end-to-end, and deploy across teams.
The Contacts API allows read-only access to contact data, tasks, notes, and appointments. You can pull or display data in your automations. If you need to update records, use separate endpoints with proper authorization.
No heavy coding is required. The Zapier App Connector provides a no-code interface to connect GHL endpoints, create triggers and actions, and map fields.
Supported authentication is OAuth 2.0. The connector handles token refresh automatically and stores credentials securely.
If a call fails, Zapier will retry based on the configured retry policy. You can also implement custom error handling in your Zap.
Common endpoints include GET /contacts/:contactId, GET /contacts/:contactId/tasks, and PUT /contacts/:contactId.
You can fetch a single contact by ID or list multiple contacts using endpoints like GET /contacts or GET /contacts/business/:businessId.
Detailed endpoint docs are available in the GHL API Reference and the Zapier app connector docs.
Due to high volume, we will be upgrading our server soon!
