Authenticate using OAuth 2.0. In Zapier, register the Contacts API app, obtain client ID and secret, and request the scope ‘contacts.readonly’ or broader as needed.
Configure OAuth credentials in the Zapier App Connector, define the authorization URL and token URL, and ensure the access token is refreshed automatically.
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: New or updated contact is detected and pulled into Zapier as a data event.
Actions: Retrieve contact details (GET /contacts/:contactId) and related tasks (GET /contacts/:contactId/tasks) for downstream automation.
GET /contacts/:contactId (and related GET /contacts/:contactId/tasks) as the primary data fetch
contactId, name, email, phone, company, lastModified, associatedTaskIds
Trigger: A new or updated contact is created in GHL and ready to sync with other apps.
Actions: Create or update a contact (POST /contacts/ or PUT /contacts/:contactId) and create associated tasks (POST /contacts/:contactId/tasks).
POST /contacts/ and POST /contacts/:contactId/tasks
name, email, businessId, taskTitle, taskDueDate
Trigger: Multiple tasks are created or updated for a single contact.
Actions: Create or update multiple tasks in a single workflow (POST /contacts/:contactId/tasks for each task).
POST /contacts/:contactId/tasks
taskTitle, dueDate, priority, status
No custom development required; build automations with clicks.
Easily connect data between GHL and other apps in real-time.
Reusable workflows and triggers across your stack.
This glossary covers endpoints, authentication, triggers, actions, and payload fields used to connect GHL’s Contacts API with the Zapier App Connector.
A URL and HTTP method used to access a specific function in the GHL API (e.g., GET /contacts/:contactId).
Process of proving the app is allowed to access GHL data, typically via OAuth 2.0 tokens.
An operation a Zapier workflow performs in response to a trigger, such as creating or updating a contact.
A signal from an app that starts a Zapier workflow, such as a new contact being created.
Capture form submissions in your form tool and push new contacts and initial tasks into GHL via the API.
Whenever a task is created in GHL, automatically create a corresponding task in your PM app.
When a ticket is updated, append a note to the contact in GHL.
Register your app, obtain client credentials, and set up the authorization URL in Zapier to authorize access to Contacts data.
Define triggers and actions, and map API fields like contactId, name, and email to your Zapier fields.
Run test zaps, verify data flow for contacts, tasks, and notes, then enable the workflow.
The Contacts API integration with the Zapier App Connector lets you read, create, update, and organize contact data from GHL within Zapier automations. You can pull contact details, associate tasks and notes, and push data to other apps. This combination enables no-code workflows that automate routine data handling. Two common use cases are syncing new leads into your CRM and updating task status when actions complete in connected apps.
Available endpoints include retrieving a single contact (GET /contacts/:contactId), listing a contact’s tasks (GET /contacts/:contactId/tasks), and accessing notes (GET /contacts/:contactId/notes). You can also fetch appointments, search by business, or list all contacts. Permissions like read-only access keep your data safe while enabling useful automation.
Yes. You can create new contacts (POST /contacts/) or update existing ones (PUT /contacts/:contactId). You can also attach tasks (POST /contacts/:contactId/tasks) and manage their status. This enables end-to-end workflows from lead capture to task execution without code.
Authentication is typically handled via OAuth 2.0. In Zapier, register the Contacts API app, obtain client credentials, configure the authorization URL, and allow token exchange to access GHL data. The app will manage token refreshing automatically to maintain a smooth connection.
The primary scope for read access is contacts.readonly, but broader scopes may be required for write actions like creating or updating contacts and tasks. Always apply the principle of least privilege, granting only what you need for your automation.
Map fields such as contactId, name, email, phone, and associated task details to your Zapier fields. Use consistent field names across apps to avoid data mismatches. You can also map custom fields as needed for your workflows.
Error logs and troubleshooting tips can be found in the Zapier app connection settings and the GHL API documentation. Common issues include token expiration, permission mismatches, and incorrect field mappings. Re-test connections after updating credentials or scopes.
