How to send multipart/form-data with PowerShell Invoke-RestMethod

Question

I\'m trying to send a file via Invoke-RestMethod in a similar context as curl with the -F switch.

Curl Example

curl -F FileName=@\"/path-to-file.na         


        

Answer 1

The problem here was what the API required some additional parameters. Initial request required some parameters to accept raw content and specify filename/size. After setting that and getting back proper link to submit, I was able to use:

Invoke-RestMethod -Uri $uri -Method Post -InFile $filePath -ContentType "multipart/form-data"
