Bearer token App Integration - authorisation failure

Hi,

I am trying to create an integration where the authorisation request that the API client request a token, then that token is used in a Bearer token for subsequent requests. As far as I understand, the Session Authentication type should be used of this, however, I am causing a 500 server error via Zapier. I have a successful authorisation mechanism setup in Postman, but can’t seem to replicate this in Zapier.

The API endpoint I am looking to use to request the token is https://cloudshare.stoplight.io/docs/AccelerateAPI/5jzyft1s3p00h-authentication

In Postman, the code I use to request the token is:

pm.sendRequest({
	url: 'https://api.accelerate.cloudshare.com/v4/oauth/token',
	method: 'POST',
	header: 'Content-Type: application/x-www-form-urlencoded',
	body: {
		mode: 'urlencoded',
		urlencoded: [
			// The CloudShare Oauth2 implemntaiton is the same as using "Client Credentiatls" in the built in Postman Oauth2 authorisation
			{ key: "client_id", value: pm.variables.get("API_ID"), disabled: false },
			{ key: "client_secret", value: pm.variables.get("API_KEY"), disabled: false },
			{ key: "grant_type", value: "client_credentials", disabled: false }                  
		]
	}
}

This result in a body that is sent similar to the following:

In Zapier, I switched to use the code view for the authentication, and even hard coded the `client_id` and `client_secret` values (as I couldn’t get the form parameter to work) but I could not get this to work in any case. It now looks like:

Test the authentication I see:

Any thoughts?

One the raw access token retravl is working, the next step to to use the response JSON that contains the `access_token` as a Bearer token with follow up requests (then refresh the token every 300 seconds as required).
