@dessislav.shekerletov,

Thank you for your query.

The gateway host and URL which you are using is correct.

Can you please confirm the API call for which you are getting Error 401? Is it just the 'Get World-Check Profile' or are you getting error for the screening request as well?

Please share the request headers and the response headers of the failed API call to look into the exact cause of the error.

Here is the code snippet

var settings = {
  "async": true,
  "crossDomain": true,
  "url": "https://rms-world-check-one-api-pilot.thomsonreuters.com/v1/reference/profile/e_tr_wco_4893024",
  "method": "GET",
  "headers": {
    "Authorization": "Signature keyId=\"<<KEYIDGUID>>\",algorithm=\"hmac-sha256\",headers=\"(request-target) host date\",signature=\"APPSIGNATURE\"",
    "Accept": "*/*",
    "Cache-Control": "no-cache",
    "Host": "rms-world-check-one-api-pilot.thomsonreuters.com",
    "accept-encoding": "gzip, deflate",
    "Connection": "keep-alive",
    "cache-control": "no-cache"
  }
}

$.ajax(settings).done(function (response) {
  console.log(response);
});
