Opening the link I was hoping that this would be a postman with better support for file uploads. I have a long lived desired to be able to have postman request which embeds a file to upload. I really like postman features and UX but when I need a test suite for a file upload endpoint it doesn't match.
Tried several hacks to achieve to embed files but none worked. If the endpoint supported Content-Transfer-Encoding it would be kind of easy to do.
