Authenticate requests using your GHL credentials with the specified scope (contacts.readonly). Keep tokens secure and rotate regularly.
Connect via OAuth 2.0 or API key-based credentials, ensuring the Zapier App Connector has the permissions to read and write contact data as needed.
Endpoints covered: 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: When a contact is retrieved or updated to pull current data.
Actions: Use GET /contacts/:contactId to fetch, then retrieve related tasks and notes with GET /contacts/:contactId/tasks and GET /contacts/:contactId/notes.
Methods: GET /contacts/:contactId; GET /contacts/:contactId/tasks; GET /contacts/:contactId/notes
Key fields: contactId, taskId, noteId
Trigger: New or updated contact data from your source system.
Actions: POST /contacts/ to create; PUT /contacts/:contactId to update.
Methods: POST /contacts/; PUT /contacts/:contactId
Key fields: contactId, businessId
Trigger: New or updated tasks for a contact.
Actions: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId
Methods: POST /contacts/:contactId/tasks; PUT /contacts/:contactId/tasks/:taskId; PUT /contacts/:contactId/tasks/:taskId/completed; DELETE /contacts/:contactId/tasks/:taskId
Key fields: contactId, taskId
Automate day-to-day data syncing between GHL and your apps without writing code.
Speed up onboarding and deployment with ready-to-use triggers and actions.
Scale workflows across teams with centralized, maintainable automations.
A quick glossary of endpoints, triggers, actions, authentication, and data mapping that power this integration.
An API endpoint is a URL pattern that performs a specific operation on the GHL API, such as retrieving a contact or updating a task.
The process of proving identity to access the API, using API keys or OAuth tokens.
A person stored in your GHL Contacts with associated tasks, notes, and appointments.
A callback URL used to deliver real-time updates to Zapier.
Capture new form submissions, then create or update a contact in GHL via the API and trigger follow-up automations in Zapier.
Listen for task changes on a contact and push updates to tools like Asana or Trello.
Mirror notes between GHL and your notes apps when changes occur.
Collect your GHL API key and set up OAuth credentials for Zapier.
Add the Contacts API triggers and actions, map fields, and test each flow.
Run end-to-end tests, monitor logs, and deploy to production.
The Contacts API provides programmatic access to your GHL contacts, enabling you to read, create, update, and organize contact records. This allows you to automate workflows and keep data in sync across apps.
No extensive coding is required; you can build powerful automations using triggers and actions in Zapier’s visual builder. A basic understanding of endpoints and data fields helps you map data accurately and handle errors gracefully.
Typical workflows rely on endpoints like GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks for tasks, and POST /contacts/ to create new records. You may also use PUT and DELETE for updates and removal as needed.
Use secure methods such as OAuth 2.0 or API keys provided by GHL, keep credentials confidential, and rotate tokens regularly. Prefer scoped access (for example, contacts.readonly) to limit permissions.
Scopes determine what you can do: contacts.readonly for reading data and contacts.write for creating or updating records. Request the minimum privileges required for your workflow.
Yes. If your credentials grant write access, you can delete contacts or tasks via the API. Exercise caution and consider safeguards like confirmation steps in Zapier flows.
Endpoint details, field mappings, and example payloads are in the developer docs and this page’s endpoint section. Test in a sandbox environment before going live.
Due to high volume, we will be upgrading our server soon!
