HTTP Post multipart/form-data

Hi,

 

I am trying to post SharePoint files to a 3rd party via their API.  Their API uses multipart/form-data.  After some trial and error, I can POSTcontent, but only text files come out correctly on the destination.  Other files (Excel, Word, jpg, etc.) post, but the data is not readable. What do I need to do to the file content to format it properly?

 

Thanks!

Hi - Can someone provide an example to submit multiple files via one POST API request.

 

Files will be available in one drive/blob location. 

We need to read all files at once and submit them to POST API by adding them one by one in form-data.

Content type : multipart/form-data; 

 

From the postman submission of multiple files in one request is possible.

 

 

Could you please tell me how you translate this into Postman? Thanks!

What exactly are you converting to base64?. It might be that the input to that is already in the right format and you're doing an extra step that breaks it

Thank you, that was the point!!!!

Thank you so much for posting this! I was experiencing the exact same thing and could not figure out what was amiss.

Hi @JonathanM ,


I did the request with the same format you did and I got the error:

 

{"description":"Validation failed","errors":[{"field":"file","message":"Unexpected/invalid field in request","code":"invalid_field"}]}
