Use OAuth or API keys to grant access to the Contacts API from APPNAME. Store tokens securely and validate the connection in your app settings before proceeding.
In APPNAME, select OAuth2 or API key method, then grant permission to your GHL account. Complete the prompts to finalize the connection.

The Contacts API is a RESTful interface that lets you read, create, update, and delete contact data within GHL. It exposes endpoints to fetch a single contact, a set of contacts, tasks, notes, and appointments associated with a contact. Use these endpoints to automate CRM workflows and synchronize data with external apps via APPNAME.
Authentication uses OAuth 2.0 and API keys. In APPNAME you’ll configure a client, authorize access, and receive tokens that authorize requests. Always store credentials securely and refresh tokens as needed, then test access with a simple GET to /contacts/ to confirm permissions.
The available endpoints cover reading contacts, tasks, notes, and appointments; creating and updating contacts; and tagging. Examples include GET /contacts/:contactId and POST /contacts/ for creating new entries; you can extend functionality with /tags and related resources.
You can update a contact with PUT /contacts/:contactId and delete with DELETE /contacts/:contactId. Handle optimistic locking and proper error responses, validate IDs, and check status codes to ensure reliable operations.
No heavy code is required thanks to the no-code connectors; you can set up automations via APPNAME’s UI and Zapier templates. However, some advanced scenarios may benefit from light scripting or using webhooks for extra flexibility.
Common errors include 401 Unauthorized, 403 Forbidden, 429 Too Many Requests, and 400 Bad Request. Implement retry strategies with exponential backoff, respect rate limits, and handle pagination to maintain reliability.
You can create tasks with POST /contacts/:contactId/tasks and notes with POST /contacts/:contactId/notes; you can also update or delete as needed. Combine tasks, notes, and tags to build robust CRM workflows across apps.
Due to high volume, we will be upgrading our server soon!
