Obtain your API credentials from the GHL developer console, enable the Contacts API scope, and generate an access token.
In Zapier, add the Contacts API connection using your GHL credentials, select the appropriate scope (contacts.readonly for viewing only), and authorize.

Automate routine CRM updates without writing code.
Trigger workflows across your favorite apps instantly.
Maintain a single source of truth by syncing data in real-time.
A quick glossary of terms used in this guide to help you build reliable automations between GHL and your tools.
A person stored in your Contacts API with basic details like name, email, and phone.
A specific API URL pattern used to perform an action, such as retrieving a contact or updating a task.
An item assigned to a contact to track completion or follow-up.
The process of proving identity to access the API, typically via tokens or OAuth.
When a new lead enters your funnel, pull contact details from GHL and enrich the record in your CRM or spreadsheet.
Create tasks in your project tool whenever a contact attribute changes, keeping teams aligned.
Push contact changes to a sheet for real-time dashboards and monthly reports.
Enter your GHL API credentials, choose scope (contacts.readonly), and test the connection.
Run a quick fetch of a contact to ensure data maps correctly to your Zap.
Create a Zap that triggers on contact events and actions downstream systems.
The required scope for read-only access is contacts.readonly. This allows you to fetch and read contact data without making changes. If you need to create or modify records, request the contacts.write scope or use the update endpoints with proper authentication.
Most endpoints listed here are RESTful GET/POST/PUT/DELETE-style, and you can invoke them from Zapier actions without code. For write operations (POST/PUT/DELETE), ensure your app has the write scope and your token is authorized.
Authenticate with GHL via OAuth or API token, then connect the Zapier App Connector using the same credentials. In Zapier, supply the client credentials and authorize access. Keep credentials secure and reuse tokens across workflows to maintain consistent data access.
Yes. The Contacts API includes endpoints to create, update, and delete contacts (POST, PUT, DELETE). Use appropriate scopes (contacts.write) and validate responses in Zapier to ensure data integrity.
Rate limits exist to protect API stability. If you hit limits, implement exponential backoff in your Zapier workflows. Consult the GHL developer docs for current quotas and best practices for batching requests.
Testing starts with a connection test in Zapier. Then run a sample Zap to fetch a contact and review mappings. Use test data and verify that IDs, names, and fields map correctly to the target app.
API responses can be inspected in Zapier task history and within GHL developer console logs. If you encounter errors, review HTTP status codes, error messages, and ensure your scopes and endpoints match the request.
Due to high volume, we will be upgrading our server soon!
