How to Access HTTP Header Values in Azure AD Claims Transformation?

Question

I have an application hosted in Azure AD that uses SSO. The application sends a custom "ABC" value in the HTTP header during the authentication process. I need to capture this value and pass it as a claim to Azure AD for further use.

From my understanding, Azure AD does not natively allow accessing HTTP headers directly in claims rules, unlike ADFS. Please confirm if I'm right.

• Is there any workaround to achieve this in Azure AD?
• Would Azure API Management or middleware be suitable for intercepting and injecting the header value into the claim?
• Are there other recommended approaches for handling such scenarios?
