Can file upload with form-data in Expose Rest Api ?

Currently, I can use postman upload file like below picture,this can work.

but I firstly used form-data to upload file, it didn't work, so I want to know why? And how?

after I using form-data to upload file, when I download the file, its content is like below, with header and footer

So if someone can tell me if we can use form-data to upload file, and how ? What's wrong with mine?

Hi Cindy,

OutSystems does not natively support multipart/form-data for sending binary files. Fortunately, I've written an extensive article on how to achieve this. If you have any more questions please let me know.
