Currently Microsoft Power Automate omits/strips off the HTTP Content-Type Header from Flow HTTP GET Requests.
This behaviour is mentioned in the documentation:
https://docs.microsoft.com/nl-nl/azure/connectors/connectors-native-http#omitted-http-headers
But this behaviour seems to conflict REST API specification and makes it impossible to consume REST APIs that require the Content-Type Header in HTTP GET Requests from Microsoft Flow.
there seems to be at least some debate/unclarity on to whether Content-Type should or should not be required in HTTP GET requests:
https://stackoverflow.com/questions/5661596/do-i-need-a-content-type-header-for-http-get-requests
https://tools.ietf.org/html/rfc7231#section-3.1.1.5
but currently the fact remains, that Flows is unusable when trying to consume REST API that do require the Content-Type header being set on GET requests.
thanks in advance,
