Hi,

I am using a demo account for World Check One APIs. I needed to consume a few APIs and display information on the Frontend (ReactJs). Can understand that due to browser's CORS policy was getting 401 response code on the Frontend but I tried consuming the API on a Node/ Express backend environment and still getting the same response code and no data. I have tested the APIs on Postman as well as Java and it is working fine but need a solution for JavaScript based Frontend and Backend.

Copying the code for reference:

// Using Axios client to consume API
const url = "https://api-worldcheck.refinitiv.com/v2/cases/screeningRequest";
  
  const body = JSON.stringify({
    groupId: "********",
    entityType: "INDIVIDUAL",
    caseId: "",
    providerTypes: ["WATCHLIST"],
    caseScreeningState: {
      WATCHLIST: "INITIAL",
    },
    name: "John Smith",
    nameTransposition: false,
    secondaryFields: [],
    customFields: [],
  });
  
  const options = {
    headers: {
      "Date": new Date(),
      "Content-Type": "application/json",
      "Authorization": authorisationCode(),
      "Content-Length": "10000",

    },
    redirect: "follow",
    body
  };
  
  axios
    .post(
      url,
      // body,
      options
    )
    .then((response) => {
      console.log("response", response);
    })
    .catch((error) => {
      console.log("error", error);
    });  

// method used to generate Authorisation Code, this is working fine
const authorisationCode = () => {
  var date = new Date().toGMTString();
  var dataToSign =
    "(request-target): get " +
    "/v2/" +
    "groups\n" +
    "host: " +
    "api-worldcheck.refinitiv.com" +
    "\n" +
    "date: " +
    date;
  var hmac = generateAuthHeader(dataToSign);
  var authorisation =
    'Signature keyId="' +
    "**********" +
    '",algorithm="hmac-sha256",headers="(request-target) host date",signature="' +
    hmac +
    '"';
  return authorisation;
};

const generateAuthHeader = (dataToSign) => {
  var hash = CryptoJS.HmacSHA256(
    dataToSign,
    "**********"
  );
  return hash.toString(CryptoJS.enc.Base64);
};

Following is the response both on Frontend and Backend respectively:

Frontend:

Backend:

    statusText: '',
