On an Azure subscription I've created an API Gateway, in which I registered an API that expose a method that accept in input a multipart/form-data request.
As can be seen in the following image, the API gateway developer portal, shows the correct content-type but the body is a simple texbox.
Instead, the swagger autogenerated by the API, shows the input disposition correctly as can be seen in the following image.
There is any way to force the API Gateway developer portal to show the input params correctly?
