New to AWS, Transcribe streamming question


I need to create a app that uses Transcribe on Unreal, but I'm just plain dumb, please guide me:

they have something like to start a session:

POST /stream-transcription HTTP/2 host: X-Amz-Target: com.amazonaws.transcribe.Transcribe.StartStreamTranscription Content-Type: application/ . . . . . so on

I can't for the life of me get past this I tried with postman, and on unreal itself, I got the IAM and everything else sorted, but I don't know if I need a function from the SDK to gerate the URL, when I try to do it myself I get:

<UnknownOperationException/> or The WebSocket handshake failed ( when using socket)

As I just started using AWS I'm lost, any guidance is welcome

Apparently the Authentication header having the credentials is missing, or the user bound to the IAM is lacking permissions to the transcribe:StartStreamTranscription API

The whole request, including the Authentication header, can be constructed manually, as described in the Setting up an HTTP/2 stream section from Amazon Transcribe documentation, or you can use the AWS SDK for JavaScript - see
