Cannot Retrieve Authorization From Response Header

[MBarimah]

Hello everyone,

I am having the same issue described in the following post: 

https://powerusers.microsoft.com/t5/Connecting-To-Data/Unable-to-retrieve-authorization-token-from-r...

I am interacting with a webservice through a POST request, and I am able successfully send information's to the web service in order to authenticate and get a response.
The API I am interacting with is designed to send the authentication token in the response header instead of the body. I am not sure why but when the response with the authorization token reaches power automate, I am not able to see the authorization header. I have executed the same exact request with Postman, and I do get the authorization header. it seem that power automate is filtering out the information from the response.
 
I have also tried to solve the issue by creating a custom connector, but it's still not returning the authorization header, the really strange thing is that when I use the testing tool to validate the implementation of the custom connector, I am able to see the authorization header, but as soon as I use the custom connector within a flow I am not able to see the authorization header

Hi @MBarimah ,

It looks like there may be a policy in the APIM which is removing/sanitizing the specific key in the responee header.

Thanks @eric-cheng 

Do you know in which section of azure I can see the policies?
