Curl request

I don't get what you say.

All you need to do is to set the correct options for the request.

If the following command works, show the debug output and know all the request headers.

Code:

curl -X POST --user '<CLIENT_ID>:<CLIENT_SECRET>' -H 'Content-Type: application/x-www-form-urlencoded' 'https://dispatchapi-sandbox-qa.auth.eu-west-1.amazoncognito.com/oauth2/token?grant_type=client_credentials'

After that, configure the options that send the exact same request headers.
That's it.
