Explanation:

Scenario: You test the Logic app in a development environment. The following error message displays:
'400 Bad Request'
Troubleshooting of the error shows an HttpTrigger action to call the RequestUserApproval function.
Note: If the inbound call's request body doesn't match your schema, the trigger returns an HTTP 400 Bad Request error.
Box 1: function
If you have an Azure function where you want to use the system-assigned identity, first enable authentication for Azure functions.
Box 2: system-assigned
Your logic app or individual connections can use either the system-assigned identity or a single user-assigned identity, which you can share across a group of logic apps, but not both.

Box 1: Validate JWT
The validate-jwt policy enforces existence and validity of a JWT extracted from either a specified HTTP Header or a specified query parameter.
Scenario: User authentication (see step 5 below)
The following steps detail the user authentication process:
The user selects Sign in in the website.
The browser redirects the user to the Azure Active Directory (Azure AD) sign in page.
The user signs in.
Azure AD redirects the user's session back to the web application. The URL includes an access token.
The web application calls an API and includes the access token in the authentication header. The application ID is sent as the audience ('aud') claim in the access token.
The back-end API validates the access token.
