The Contacts API uses standard API key or OAuth-based authentication. Ensure your GHL account has API access enabled and securely store credentials in Zapier.
Zapier handles authentication for you via OAuth 2.0 or API tokens, depending on the connector setup. Use the provided credentials in your Zapier account.

Core elements include authentication, endpoints, triggers, actions, and data fields. Processes cover mapping, error handling, and testing.
Methods used to verify identity and authorize access to the GHL API, such as API keys or OAuth tokens.
A specific URL path in the GHL API used to perform an action or retrieve data, e.g., GET /contacts/:contactId.
An event in an app that starts an automation in Zapier, such as a new contact or updated field.
A task performed by the integration in response to a trigger, such as create a note or update a contact.
Capture new leads from forms and automatically create contact records in GHL via the Contacts API.
Create tasks in GHL when events occur in your PM or CRM apps, keeping teams aligned.
Tag contacts and attach notes from any connected tool to enrich contact records.
Obtain API credentials from GHL and configure them in Zapier.
Map endpoints to Zapier triggers and actions for contacts
Run test pings, validate data, and enable automations.
The Contacts API exposes several endpoints to read and manipulate contact data. Typical usage includes GET /contacts/:contactId to fetch a contact’s details, GET /contacts/:contactId/tasks to review related tasks, and GET /contacts/:contactId/notes for notes tied to a contact. For write and update actions, you can use POST /contacts/ to create, PUT /contacts/:contactId to update, and DELETE /contacts/:contactId to remove a contact. CUSTOM endpoints like GET /contacts/:contactId/appointments or GET /contacts/business/:businessId enable broader data retrieval. The exact endpoints you enable depend on your automation needs and the permissions granted by your GHL account.
No advanced coding is required to connect the Contacts API with the Zapier App Connector. Zapier provides a user-friendly interface to configure triggers and actions based on the available endpoints. You can map fields, set up authentication, and test automations using guided wizards. If you need more complex logic, you can still craft multi-step flows within Zapier using its built-in tools, but coding is not required for standard connections.
A read-only scope is sufficient for many read-based automations such as syncing contact lists, viewing tasks, or pulling notes. However, to create or modify data (for example, creating a contact or updating a task), you will need write permissions. Review your use case and request the appropriate scope from your GHL admin to enable the required actions.
Authentication is handled at the connector level. GHL typically supports API keys or OAuth tokens, while Zapier manages its own OAuth 2.0 flow or API tokens depending on the integration. You will securely connect your GHL account in Zapier, authorize the requested permissions, and then the connector will automatically attach the necessary credentials to each API call.
Yes. The integration supports creating tasks, notes, and tags via endpoints such as POST /contacts/:contactId/tasks, POST /contacts/:contactId/notes, and POST /contacts/:contactId/tags. This enables you to build workflows that grow with your team’s needs, from onboarding to ongoing contact management.
Testing is done through Zapier’s test feature inside the connector setup. Run a test to fetch data, create a sample contact, or add a task to verify that mappings are correct and error handling is in place. After successful tests, deploy your workflow to run automatically in production and monitor for any API errors.
Due to high volume, we will be upgrading our server soon!
