To access Contacts data from the GHL Contacts API, configure your credentials in GHL and grant the Zapier App Connector the necessary scope (contacts.readonly). Keep credentials secure and rotate them regularly.
Approve the Zapier App Connector to access your Contacts data within GHL. When prompted, select the Contacts API scope and authorize the connection.

The Contacts API lets you read, create, update, and delete contacts, tasks, and notes to drive automations with the Zapier App Connector. It is designed for reliable, scalable integrations with rate limits and security best practices. Use the appropriate HTTP methods (GET, POST, PUT, DELETE) as described in the endpoint list to implement your workflows.
Permissions vary by your plan and scope. For read-only workflows, use contacts.readonly; for full CRUD operations, include write permissions as needed. Keep credentials secure and rotate keys regularly. If you’re collaborating with a team, assign least-privilege access and regularly review your app connections.
Secure authentication uses token-based or OAuth flows supported by GHL. Store tokens securely and avoid exposing them in client-side code. If you rotate tokens, update your connectors promptly. Prefer server-side credential storage and periodic audits of access permissions.
Yes. Use the test or sandbox environment if available, or create test contacts and records to validate automations. Always back up data before large changes. Perform end-to-end testing to ensure field mappings and triggers behave as expected.
Read endpoints typically use GET, while write endpoints use POST, PUT, or DELETE. The documentation lists each endpoint with its method and parameters. Use the correct scope for the intended operation. For bulk actions, check rate limits and batch sizing guidelines.
Map fields by matching source fields to GHL contact fields within your Zap. Use dynamic mappings and fallback values. Validate required fields like email. Test mappings with sample data to ensure consistency across systems.
Endpoint definitions are available in the API reference section of this guide. You can also export a formal schema for integration planning. Refer to the endpoint section for examples and required parameters.
