Use OAuth 2.0 with the contacts.readonly scope to securely access contact data. Obtain client credentials from your GHL API dashboard and configure your Zapier app to exchange tokens for authenticated requests.
In Zapier, set up OAuth credentials or API key-based auth to securely connect to the GHL Contacts API. Ensure token refresh is handled automatically and scopes are limited to what your automation requires.

Understand the core API elements and processes used when connecting GHL Contacts API with the Zapier App Connector.
Application Programming Interface that allows one app to communicate with another by requesting and exchanging data.
A specific URL path in an API that performs a defined operation, such as retrieving a contact or creating a task.
The process of proving identity and granting access to API resources, typically via OAuth tokens or API keys.
The maximum number of API requests allowed in a given time window to protect service stability.
When a new signup occurs, automatically create a contact in GHL via the Contacts API and kick off onboarding tasks in Zapier.
Create or update tasks in GHL when items appear in your project management tool, keeping teams aligned.
Capture important email notes into contact records to preserve context and history.
Obtain API keys and authorize in Zapier to enable secure data access.
Select endpoints (GET, POST, PUT, DELETE) and map fields between GHL and Zapier.
Run end-to-end tests, verify data flow, and deploy automations to production.
The Contacts API integration with GHL via Zapier lets you read contact data and related resources to automate CRM workflows. You can build triggers and actions that surface contact details, associated tasks, and notes directly in your automation flows. To keep data secure, ensure your OAuth tokens are stored safely and that scopes are limited to what your automation requires.
With the contacts.readonly scope, you can retrieve contact information and related data without altering records. This is ideal for reporting, dashboards, and read-only workflows that monitor activity or surface insights. If you need to modify data, you’ll need to request broader permissions and implement strict access controls in your Zapier app configuration.
Endpoints for managing contacts include: GET /contacts/:contactId to retrieve a single contact, GET /contacts/ to list contacts, POST /contacts/ to create, PUT /contacts/:contactId to update, and DELETE /contacts/:contactId to remove a contact. You can also manage related tasks with endpoints like GET /contacts/:contactId/tasks and POST /contacts/:contactId/tasks.
Authentication is handled via OAuth 2.0 or API keys, depending on your setup. Keep tokens secure, refresh them automatically, and only request necessary scopes. Regularly review app permissions and rotate credentials as part of your security hygiene.
Yes. You can create tasks for a contact using POST /contacts/:contactId/tasks and update them with PUT /contacts/:contactId/tasks/:taskId. You can also mark tasks as completed with PUT /contacts/:contactId/tasks/:taskId/completed, enabling smooth task workflow automation.
Notes are supported through endpoints such as GET /contacts/:contactId/notes and POST /contacts/:contactId/notes, allowing you to attach context and history to each contact. Tags can be managed by using the relevant tag endpoints in association with contacts when available in your GHL setup.
Rate limits vary by endpoint and plan. Plan for retries with exponential backoff and design automations to batch requests where possible. Always monitor API usage in the Zapier app and implement caching where appropriate to minimize unnecessary calls.
Due to high volume, we will be upgrading our server soon!
