The Contacts API uses OAuth 2.0 with a read-only scope (contacts.readonly). To connect, create a GHL app, obtain client credentials, and authorize access to your contacts data. Use the redirect URL provided by Zapier App Connector to complete the flow and securely store tokens.
In theZapier App Connector, configure OAuth 2.0 for the Zapier app you’re connecting. Exchange authorization codes for access tokens and refresh tokens, then map tokens securely in Zapier. Follow best practices to keep credentials confidential.
– GET /contacts/:contactId — Retrieve a single contact – GET /contacts/:contactId/tasks — List tasks for a contact – GET /contacts/:contactId/tasks/:taskId — Retrieve a specific task – GET /contacts/:contactId/notes — List notes for a contact – GET /contacts/:contactId/notes/:id — Get a specific note – GET /contacts/:contactId/appointments — Get appointments for a contact – GET /contacts/ — List contacts – GET /contacts/business/:businessId — Get contacts by business – contacts.write — Write scope for contact data permissions – POST /contacts/ — Create a new contact – PUT /contacts/:contactId — Update a contact – DELETE /contacts/:contactId — Delete a contact – POST /contacts/:contactId/tasks — Create a task for a contact – PUT /contacts/:contactId/tasks/:taskId — Update a task – PUT /contacts/:contactId/tasks/:taskId/completed — Mark a task as completed – DELETE /contacts/:contactId/tasks/:taskId — Delete a task – POST /contacts/:contactId/tags — Add tags to a contact
Trigger: Access or update a contact to pull core details, then fetch related tasks.
Actions: Use GET /contacts/:contactId to retrieve the contact, then GET /contacts/:contactId/tasks to list tasks. Optional POST/PUT calls can create or update tasks as needed.
GET /contacts/:contactId
contactId
Trigger: Open a contact to view notes
Actions: Retrieve notes via GET /contacts/:contactId/notes and GET /contacts/:contactId/notes/:id for detail.
GET /contacts/:contactId/notes
contactId, id
Trigger: Task creation or updates are needed for a contact
Actions: Create tasks with POST /contacts/:contactId/tasks, update with PUT /contacts/:contactId/tasks/:taskId, mark completed with PUT /contacts/:contactId/tasks/:taskId/completed, or delete with DELETE /contacts/:contactId/tasks/:taskId.
POST /contacts/:contactId/tasks
contactId, taskId
No programming required. Set up data flows between the GHL Contacts API and other apps using a visual, drag-and-drop interface in the Zapier App Connector.
Automate repetitive workflows—sync contacts, tasks, notes, and tags across systems without writing code.
Scale easily with built-in error handling, retries, and monitoring to keep data accurate and up-to-date.
This glossary covers core concepts used when building no-code integrations between the GHL Contacts API and the Zapier App Connector.
The set of endpoints exposed by GHL to access Contacts, Tasks, Notes, Appointments, and related resources.
A specific URL path in the API that performs a defined operation, such as retrieving a contact or updating a task.
An event in a workflow that starts a Zapier automation, such as a new contact or a change in a task.
The process of verifying identity and obtaining permission to access API resources, typically via OAuth 2.0.
When a form is submitted, create or update a contact in the Contacts API (POST /contacts/) and attach relevant tasks or notes. This keeps your CRM current without manual entry.
Capture or update contact appointments via GET /contacts/:contactId/appointments and push them to a calendar app for reminders and scheduling.
Automatically tag contacts when certain criteria are met using POST /contacts/:contactId/tags, enabling smarter list segmentation.
In the GHL developer console, create a new app. Set the Redirect URI to the Zapier App Connector, and obtain client_id and client_secret for OAuth authentication.
Use Zapier to initiate the OAuth flow, grant access to contacts.readonly, and securely store the tokens for ongoing use.
Test each endpoint in a sandbox, verify data is synced correctly, set up error notifications, and then deploy to production.
GHL uses OAuth 2.0 for secure access. You’ll authenticate through the GHL developer platform to obtain an access token with the contacts.readonly scope. This token is used by Zapier App Connector to call the API on your behalf. Regular token refreshes keep your connection active without manual intervention. Ensure your OAuth client credentials are kept confidential and rotate them periodically to maintain security.
Read-only access covers operations like retrieving contacts, tasks, notes, and appointments. Endpoints such as GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, and GET /contacts/:contactId/appointments are designed for safe data viewing and aggregation in automation workflows. If you need write capabilities later, you can request expanded scopes or adjust permissions within your GHL app configuration.
By default, the integration can be configured for read-only access. Writing data requires appropriate scopes (e.g., contacts.write) and explicit authorization from your GHL admin. In your Zapier app, you would enable the write paths (POST, PUT, DELETE) after you’ve secured the necessary permissions. Always test write actions in a sandbox environment before enabling in production to prevent unintended data changes.
Common required fields include a valid contactId for retrieving or updating a contact, and taskId for editing a specific task. For creating new records, ensure required fields such as name, email, or a unique identifier are provided per your GHL configuration. Always refer to the API’s schema for the exact required fields and data types.
Due to high volume, we will be upgrading our server soon!
