Does EM support multipart/form-data? I know this setup works in PowerAutomate, I’m struggling to get it to work with EM.

Hi @nicktagz
The WebRequest/IterateWebRequest actions support the multipart/form-data content type.
Just change the Body type to the File (multi-part).
Seems that the expected field name for the file is FileName. However, check this with the API documentation.
You should enable the Additional parameters to send a form with a file. And fill out the form accordingly.
Also, you may set the Content-Type header. However, in the case of multipart file upload, this must be an actual content type (like application/pdf for the .pdf files, or application/octet-stream). But this is optional, and it depends on your API.
A preview mode (opened when the Show Preview button is clicked) will show a near-to-real request body.
Hm. Any error message?
Also, please provide a link to the API documentation.
I’m going to ask the developer for documentation on the API.

To check.
When you press Show Preview, does the preview contains Content-Type multipart/form-data and boundary?
Try to change WebRequest:
File.FileName. And set it to the file name.Content-Type headerThank you, that worked. The primary Field name needed to be “File” and filename as an additional parameter. Appreciate the help!
