The configuration of GitHub Webhooks in an Identity Provider (IDP) typically occurs at the Application Level, which corresponds to Option 2. You configure Webhooks at the application level to enable specific events or actions to trigger notifications or other actions within the application when certain events occur in your GitHub repositories. This allows for integration and automation between your IDP and GitHub.

Option 1 (Pipeline Level) and Option 3 (Portfolio Level) are less common in the context of configuring GitHub Webhooks, as these levels of configuration are typically associated with different aspects of project management and deployment, rather than the integration of external services like GitHub.

Option 4 (There is no WebHook feature in IDP) is not accurate, as many IDPs and application platforms do support Webhooks for integrating with external services like GitHub. However, the availability and configuration process of Webhooks may vary depending on the specific IDP and application you are using.
