making post with multipart/form content-type

What is the correct way to set the headers/body to be able to make a post request with a multipart/form content-type? I can’t figure out where these should go (or where to put them):

----Z7depKeH0iSSjand
Content-Disposition: form-data; name="file"; filename="test.csv"
Content-Type: text/csv

----Z7depKeH0iSSjand
Content-Disposition: form-data; name="filename"

test.csv
----Z7depKeH0iSSjand

This is what I currently have:

    const csv = makeRequest(); // does a GET, stores the csv from that response into a buffer 
    const opts = {
      headers: {
        'Content-Type': 'multipart/form-data; boundary=----Z7depKeH0iSSjand',
        'Accept-Encoding': 'multipart/form-data',
        'X-AUTH-TOKEN': authToken,
      },
      body: csv,
    }
    request('POST', url, opts)

Excellent, that’s exactly the right use case for this library. I am also working on supporting synchronous multi-part form upload so that should be here soon.

Hey @ForbesLindesay can you please help - I still get 415 error on this request -

const request = require(‘sync-request’) const FormData = request.FormData;

	let form1 = new FormData()
        form1.append('grant_type', '*****')
		form1.append('username', '******')
		form1.append('password', '******')
		let res = request('POST', 'https://********healthsuite.com/authorize/oauth2/token', {
		  headers: this.getAppHeaders(), form :form1
		})
		console.log(res)
