How to authenticate with a REST API that requires authentication with an application/x-www-form-urlencoded body

I am trying to setting a flow to call a REST API. I set up an HTTP step.  How do you do this in Flows? I can API call just fine.


The problem I'm having is that the REST API requires me to authenticate and get an access token using. I always get invalid grant type because I can't seem to pass application/x-www-form-urlencoded which is requires.





accept application/json



Javascript equivalent that works is:

var settings = {
  "headers": {
  "data": {

$.ajax(settings).done(function (response) {


grant_type: password

When you're passing the token in the URL/URI, have you tried passing it using the encodeUriComponent() function in an expression?


I'm not suggesting this will resolve the issue, but maybe there are characters that aren't being passed correctly in the URI.
