Access to the Contacts API is controlled by a scoped token. Scope: contacts.readonly. Use your GHL credentials to obtain a token and authorize requests.
OnlineCourseHost authenticates to GHL using the partnered integration flow. Store credentials securely and rotate them regularly.

The Contacts API provides access to read and manage contact records within the GHL system. It enables you to fetch contact details, tasks, notes and more from OnlineCourseHost. Start by obtaining a token with the required scope and proceed to call the endpoints shown earlier.
Read access requires the contacts.readonly scope. Ensure your app requests the least privileged scope needed and handles the token securely. Regularly rotate credentials and monitor access logs.
Authenticate by exchanging your app credentials for an access token. Include the token in the Authorization header of each request. Use the standard OAuth or API key flow supported by the GHL integration.
The most useful endpoints for syncing are GET /contacts/:contactId, GET /contacts/, POST /contacts/ and PUT /contacts/:contactId. These cover retrieval, creation and updates.
Yes. You can create new contacts with POST /contacts/ and update existing records with PUT /contacts/:contactId. Be mindful of data consistency and error handling.
Respect rate limits by batching requests where possible. Implement exponential backoff and retry with appropriate error handling in your app.
GHL stores data securely and provides access controls. Use HTTPS, store tokens securely, and implement least privilege access for all integration components.
Due to high volume, we will be upgrading our server soon!
