How can have form-data option in request body in Azure Portal, Azure API management test

Question

I want to send my file in my request, I already choose the multipart/formdata in the header but can't see option form-data in the request body. Did I make a mistake at any step?

Bui Tuan Anh Thank you for posting your question in Microsoft Q&A. In Azure portal test blade, multipart/formdata is not supported yet and you can only upload binary data. Here are the other options to test the API in API Management.

• Use Postman - Postman supports uploading file with content type multipart/formdata and here is doc reference: https://www.postman.com/postman/workspace/postman-answers/documentation/13455110-00378d5c-5b08-4813-98da-bc47a2e6021d you can follow.
• Developer Portal Test Console - In Developer portal test console, you have the option to attach the file for OpenAPI V2. OpenAPI V3 support is not there yet and here is the open issue: File upload not working for multipart/form-data

Note: Make sure that you define API with OpenAPI specification and add endpoint with request body "content-type = multipart/form-data" as shown in the screenshot.

Hi from the year 2025, is there a reason why this isn't supported still?
