Frequently asked questions

What is the Contacts API in GHL?

The Contacts API is the developer interface that lets apps access and manage contact data stored in GHL. It exposes endpoints to read and update contacts, as well as related entities like tasks notes and appointments. This enables Mailmeteor to personalize campaigns based on real time contact data. The API supports standard authentication and role based access to protect data.

You can start with no code by using Mailmetors built in connectors and triggers. If you need more control you can use API keys and webhooks to customize flows. Both approaches avoid writing backend code and keep setup rapid.

To begin, use essential endpoints such as GET /contacts/:contactId to fetch a contact, GET /contacts/:contactId/tasks to retrieve tasks, and POST /contacts/ to create new contacts. From there you can extend to notes and appointments as your automation grows.

Secure authentication starts with least privilege scopes and secure storage of keys. Use OAuth when available and rotate credentials regularly. Do not expose keys in client side code and monitor access with audit logs.

Yes. You can sync tasks and notes by calling the corresponding endpoints and pushing updates into Mailmeteor campaigns. Ensure you track IDs and timestamps to keep data consistent.

Endpoint details are documented in the GHL developer documentation and the integration guides provided here. This page summarizes core endpoints like /contacts and /contacts/:contactId/tasks for quick reference.

Yes. A no code setup is possible using the built in connectors and event triggers. For advanced automation you can leverage API calls and webhooks without writing code.
