This article explains how to authenticate your user with Instagram using GeneXus Access Manager (GAM).
You need to use OAuth 2.0 Authentication Type and some configuration on both sides: the Meta for Developers portal and the GAM's backend.
1. Enter to the GAM's Backend and go to the Authentication Types section. Create a new OAuth 2.0 Authentication Type, define basic information in the General section: Name, Description, Images (optional), etc.
2. In the Configuration section you need to define the following for the General, Authorization, Token and User Information tab:
Client ID: client_id Value: <clientid>
