Authenticate to the GHL Contacts API using OAuth 2.0 and your GHL account credentials. The connection typically uses the readonly scope to limit access to reading contact data.
In Zapier, authenticate the connector to GHL via OAuth 2.0. Tokens are securely stored and refreshed automatically for uninterrupted automations.
Key endpoints 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, 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 contact by ID to kick off downstream actions.
Actions: Pull the contact’s details, its tasks, and associated notes to sync with a CRM or support tool.
GET /contacts/:contactId
contactId
Trigger: New task creation for a contact to coordinate follow-ups.
Actions: Create, update, complete, or delete tasks for a contact.
POST /contacts/:contactId/tasks
contactId and task fields (title, due date, status)
Actions: Read notes for a contact and fetch individual note details to attach to records.
GET /contacts/:contactId/notes
contactId, noteId
Automate cross-app workflows without writing a line of code.
Orchestrate data flows between GHL, email, calendars, and CRMs from a single interface.
Scale campaigns and support processes with repeatable, testable automations.
A quick glossary of terms and core processes used when integrating the GHL Contacts API with Zapier App Connector.
API: A collection of endpoints that allow programs to read and modify your GHL data.
OAuth 2.0 tokens are used to securely authorize requests between Zapier and GHL.
A URL path you call to perform a specific action (read, create, update, delete) inside the API.
Permissions granted to the connector, such as readonly, to limit what can be done with the API.
Automatically create or update a GHL contact when a new lead enters your email marketing list.
Create and update contact tasks from ticket updates in your helpdesk.
Attach notes to contacts and trigger reminders when important notes are added.
Open the Zapier app, choose the GHL connector, and authenticate using OAuth 2.0 to grant permissions.
Select your GHL account and authorize data access to the Contacts API within the app.
Create a Zap that uses the Contacts API endpoints to automate your processes.
The GHL Contacts API provides programmatic access to contact data, tasks, notes, and more. You can integrate it with Zapier to automate workflows without writing code. For example, you can pull a contact by ID and fetch its tasks and notes to sync with your CRM.
No-code connections are a core benefit of the Zapier App Connector. You configure triggers and actions in a visual editor and rely on OAuth 2.0 for secure auth. If you need more customization, you can still use API endpoints directly in advanced workflows.
Common endpoints for contact management include GET /contacts/:contactId, GET /contacts/:contactId/tasks, GET /contacts/:contactId/notes, POST /contacts/, and PUT /contacts/:contactId. These allow reading, creating, and updating contacts and related data.
All authentication uses OAuth 2.0 with access and refresh tokens. The Zapier app securely stores credentials and tokens, and reauth flows guide you if permissions lapse.
Yes. The API supports read and write operations depending on the granted scope. The example here uses readonly scope, but you can request broader permissions for create and update when needed.
You can test endpoints directly from the Zapier test console or by running a sample Zap. Validate responses, check status codes, and inspect returned data to verify correctness.
API rate limits vary by plan. Check the GHL API docs for current quotas and implement retries with exponential backoff to maintain reliability.
Due to high volume, we will be upgrading our server soon!
