Genesys Cloud - Main

Hi,

I'm new to all of this and I am currently working on my first Genesys Cloud integration. When trying to authorize my application via OAuth2, I keep getting this error screen:

I've double and triple checked that my redirect URI is accurate down to the character. Any pointers here?

I'm writing in Google Apps Script and here is a snippet of the code I'm working with. Thanks in advance!

/**
 * Authorizes and makes a request to the API.
 */
function run() {
  var service = getService();
  if (service.hasAccess()) {
    var url = 'https://apps.mypurecloud.com/api/v2/authorization/divisions';
    var response = UrlFetchApp.fetch(url, {
      headers: {
        Authorization: 'Bearer ' + service.getAccessToken()
      }
    });
    var result = JSON.parse(response.getContentText());
    Logger.log(JSON.stringify(result, null, 2));
  } else {
    var authorizationUrl = service.getAuthorizationUrl();
    Logger.log('Open the following URL and re-run the script: %s',
        authorizationUrl);
  }
}

/**
 * Reset the authorization state, so that it can be re-tested.
 */
function reset() {
  getService().reset();
}

/**
 * Configures the service.
 */
function getService() {
  return OAuth2.createService('Genesys')
      // Set the endpoint URLs.
      .setAuthorizationBaseUrl(
          'https://login.mypurecloud.com/oauth/authorize?client_id=<' + 
          CLIENT_ID + 
          '>&response_type=code&redirect_uri=<' + 
          REDIRECT_URI + 
          '>')
      .setTokenUrl(
          'https://apps.mypurecloud.com/oauth/token')

      // Set the client ID and secret.
      .setClientId(CLIENT_ID)
      .setClientSecret(CLIENT_SECRET)

      // Set the name of the callback function that should be invoked to
      // complete the OAuth flow.
      .setCallbackFunction('authCallback')

      // Set the property store where authorized tokens should be persisted.
      .setPropertyStore(PropertiesService.getUserProperties());
}

/**
 * Handles the OAuth callback.
 */
function authCallback(request) {
  var service = getService();
  var authorized = service.handleCallback(request);
  if (authorized) {
    return HtmlService.createHtmlOutput('Success!');
  } else {
    return HtmlService.createHtmlOutput('Denied.');
  }
}
