Your payload does not contain any image data. That's plain to see.

Please see my answer at Creating File: File is mandatory for an example of the correct MIME payload. The same MIME rules apply with binary images as with text; you can't just change the format and try to include a remote src! You need to make a POST containing the file, not a reference to a remote file.

Also, screenshots are a bad idea here unless you show all your control characters, since extra/missing line breaks and extra spaces are prime causes of MIME formatting errors.

Hi Sanford,

I have followed the below steps:

- Used endpoint : /rest/asset/v1/files.json

- Used header as Content-Type: multipart/form-data.

- Used body text as you suggested in this Creating File: File is mandatory​

   

   

I'm using Rest API google extension and got below response:

Please let me know where the error in code so i can correct it. Actually, we want to import image files(JPG, PNG and GIF) into the marketo, If you know please help us on that .

Thanks in advance!

You can't just randomly insert line breaks, as linebreaks (CRLF) are part of the essential structure of MIME. I thought I was crystal-clear about this when I wrote:

Also, screenshots are a bad idea here unless you show all your control characters, since extra/missing line breaks and extra spaces are prime causes of MIME formatting errors.

Your screenshot also shows some random Velocity #set() syntax outside the MIME boundaries. I have no idea why that is in there. This task has no relation to Velocity and the payload will break from that alone.

Also, I don't understand how you can say you used my payload from the other thread when yours looks totally different.  Do you really not see the giant differences: the extra line breaks and the extra Velocity code?

While assembling a File API payload is not difficult, it requires close attention to detail. If you're not comfortable with the precision required to get this working, you'll need to hire a professional developer.
