The APIs have been working fine a few days ago, but today we are suddenly getting 401 Unauthorised on all API calls via postman and also dot net. We even tried regenerating the api key and secret, again imported the api collection and environment and added the new key and secret, but we are still getting 401 un-authorised.
Could you please help us with this? Thank you.
Below is a raw of my Postman Console:
GET /v2/reference/countries HTTP/1.1 Date: Mon, 14 Mar 2022 22:28:19 GMT Authorization: Signature keyId="540a9335-98da-41c8-9fe3-e2b17dbd0272",algorithm="hmac-sha256",headers="(request-target) host date",signature="X2YF4zagVg9tlWztCZGGZMni/oBRJKtZ7jHClYmrSwo=" User-Agent: PostmanRuntime/7.29.0 Accept: */* Postman-Token: c8dedaf1-8298-4722-95cd-62946cfc1b0a Host: api-worldcheck.refinitiv.com Accept-Encoding: gzip, deflate, br Connection: keep-alive HTTP/1.1 401 Unauthorized Date: Mon, 14 Mar 2022 22:26:48 GMT Transfer-Encoding: chunked Connection: keep-alive Content-Security-Policy: default-src 'none'; frame-ancestors 'none' Strict-Transport-Security: max-age=15552000; includeSubDomains X-Frame-Options: DENY X-XSS-Protection: 1; mode=block X-Content-Type-Options: nosniff Authorization: WWW-Authenticate: Signature realm="World-Check One API",algorithm="hmac-sha256",headers="(request-target) host date content-type content-length"
Hi @subarik, Thank you for reaching out to us!
You get the 401 error when the request has failed an authorization check. This can happen for a variety of reasons, such as an invalid or expired API key, an invalid HMAC signature or a request timing issue/problem with the Date header value. The API client should ensure a correctly synchronized clock is used to generate request timestamps.
However, Based on the Postman Console you shared with us, it seems that there is difference (~120) between the request header timestamp and the response header time stamp which basically mean the clock is not synchronized. Could you please adjust the system clock as per NTP and the server response having the time difference of not more than 30 seconds and then try again?
Please feel free to reach out for any further assistance.
I have a problem accessing the World-check-one API. Please help me. The same request parameter, in which the name parameter is Chinese, returns 401 Unauthorized, the name can be changed to English after the normal request.
