Identity

App registration
An app registration is the identity profile for an application, not the application code itself. It tells Microsoft Entra ID how the app is allowed to sign in users or request tokens. It contains values developers copy into configuration, such as client ID, tenant, redirect URI, credentials, and permissions. When sign-in breaks, consent fails, or tokens contain the wrong audience, the app registration is often where engineers look first. It is the contract between the app, Entra ID, administrators, and downstream APIs.

Event Grid webhook endpoint
An Event Grid webhook endpoint is an HTTPS endpoint configured as an event handler that validates ownership and receives Event Grid events over HTTP. Teams use it to send Event Grid events to a custom HTTPS application, API, Azure Function HTTP trigger, automation webhook, or supported workflow endpoint. It is not a storage queue, Event Hubs destination, or an endpoint that can skip Event Grid validation. In production, confirm the source, subscription, destination, filters, schema, identity, retry behavior, failure handling, monitoring, and owner before treating the route as safe.
