Curl works, attempting it programmatical. thoughts?

[Anonymous]

using this (not as is, $parameters are filled in as it runs:

c:\day1\i386\curl.exe -i -F format=$format -F file=@$file -F access_token=$token $hostw/bulk/v1/leads.json -F listId=$list

I am able to upload lead data into Marketo via the CURL command above  The $variables are populated during execution.  Works fine.

below is WHAT i think it should be for powershell to upload the same file, or close to this.

Invoke-RestMethod -Uri "$hostw/bulk/v1/leads.json?access_token=$token" -Method Post -InFile $file  -ContentType 'multipart/form-data'

is that even possible to reproduce ?

Alex, in all seriousness, any time spent bending PS to your will would be better spent either retrenching with batch file syntax or using something like JJS or NodeJS (command-line JS). I feel the rewards for your dev skills will be worth the struggle. My $0.02...

I think this should work with your given IRM( based on what's given here http://stackoverflow.com/questions/22491129/how-to-send-multipart-form-data-with-powershell-invoke-r... ), but the format param is required for import, so your URI needs "&format=<listFormat>.  Ideally you would do this as part of the request body, but I'm coming up dry on finding an easy way to comingle file and non-file content in a powershell multipart request.
