Need assistance on integrating with World Check One API

ANKUR SARASWAT · August 2021

Hi All,

We are integrating with World Check One API using javascipt, through which we will be sending requests with the help of XMLHttpRequest Functions.

Here, I am facing below mentioned issues while integrating with World Check One v2.43 API -

1) setting dataToSign variable,

2) correct latest currentDate variable in required Format, and

3) getting "Uncaught ReferenceError: CryptoJS is not defined error".

Can you please help me with my above issues?

Thank You for your valuable time in advance.

Hi @ANKUR SARASWAT

The Reported Error Normally occurs When Server Doesn't return the HTTP Headers required by the CORS Standard. Kindly Reconfigure the API to meet the CORS Standard and Enable CORS for Rest API.

Below link has the solution for CORS error

Hi All,

Resolved above mentioned issues by incorporating proper format for both the variables (Issue #1 and #2). Also, resolved Issue #3 CryptoJS error by including its relevant <script></script> tag after referring its CDNJS link for the latest version.

Now, I am facing "Access to XMLHttpRequest at 'https://api-worldcheck.refinitiv.com/v2/groups'; from origin 'null' has been blocked by CORS policy" error.

Can you please help me with this CORS Error?

Thank You for your valuable time in advance.

Please help. I am still not able to resolve this issue. Referred below mentioned links as well -

https://community.developers.refinitiv.com/questions/33169/access-control-allow-origin.html

None of this is working for me. Error message - Access to XMLHttpRequest at 'https://api-worldcheck.refinitiv.com/v2/groups'; from origin 'null' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Hi @Vivek Kumar Singh,

Thank You for your valuable inputs.

I am able to bypass that CORS Error and successfully make API Calls via Firefox Browser. Basically it was not able to bypass CORS via Browsers using XMLHttpRequest() function and none of the Browser Extensions to disable CORS were working for me. So instead I tried with fetch() function and it seems to be working now using mode: "no-cors" property. I am getting 200 Status Responses in Firefox.

Just wanted to confirm what's the ideal behavior for these links. Right now we are getting below responses -

https://rms-world-check-one-api-pilot.thomsonreuters.com/v2/groups

This site can’t be reached

The connection was reset.

Try:

Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics

ERR_CONNECTION_RESET

https://api-worldcheck.refinitiv.com/v2/groups
This page isn’t working

If the problem continues, contact the site owner.

HTTP ERROR 401

Can you please share some more insights on that? Thank You for your valuable time and support.
