How to connect Rezdy to the GHL Contacts API

Bridging Rezdy with the GHL Contacts API for seamless contact, task, note, and appointment sync.

Step-by-step guide to link the Contacts API with Rezdy for automated data flow.

This integration enables bidirectional data flow between Rezdy and the GHL Contacts API, including contacts, tasks, notes, and appointments. You’ll authenticate securely, configure endpoint access, and map fields to keep data consistent across systems.

Authentication for the Contacts API

Authenticate to the GHL Contacts API using OAuth 2.0 tokens with appropriate scopes (read for viewing, write for updates). Store tokens securely and rotate them on a regular schedule.

Rezdy authentication considerations

Rezdy connects to GHL using authorized credentials. Keep your Rezdy API key or app credentials safe, and restrict access to a minimum set of permissions necessary for the integration.

Frequently Asked Questions

What is the GHL Contacts API?

The GHL Contacts API is a RESTful interface that lets you read and update contact data, tasks, notes, and appointments associated with a contact. It provides endpoints to fetch individual records and list related items like tasks or notes. With the Rezdy connector, you can surface these capabilities in a no-code fashion through the integration layer, enabling automation and data synchronization without writing code.

No code is required to set up the integration; you configure triggers, actions, and field mappings in the app connector interface. A basic understanding of endpoints and fields helps you design accurate sync rules. If you need custom logic beyond built-in templates, you can add optional code steps or use webhooks for advanced scenarios.

The endpoints covered include reading and writing contacts, as well as related tasks, notes, and appointments (e.g., GET /contacts/:contactId, GET /contacts/:contactId/tasks, POST /contacts/). This page focuses on the core endpoints used to read, create, update, and delete contacts, and to manage tasks, notes, and appointments associated with those contacts.

Authentication uses OAuth 2.0 tokens and TLS for secure connections. Tokens should be stored securely and rotated on a regular schedule. The integration applies least-privilege scopes to limit access to only what is required.

Yes. Real-time or near real-time data sync is achievable by using triggers and webhooks configured in the connector. Depending on the plan, you can opt for polling where immediate updates are not critical. Monitoring ensures data remains consistent across both systems.

To test, run connection tests within the integration UI, simulate common workflows (create/update contact, add tasks, note updates), and review logs or dashboards for errors. Use sample data to validate field mappings and ensure data integrity across both systems.

Mappings and field filters are managed in the integration’s mapping screen. There you can align fields like email, name, phone, and custom attributes between Rezdy and the GHL Contacts API, enabling precise data synchronization and easy maintenance.
