Curl request

If you don't know how to send a correct request, nobody cannot help you.
Why don't you ask to the technical support of the api provider?

I don't know how to translate this :

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'

to ci code ....

The api is written from booking.com developer  I think it works
