Hi all,

I am trying with notification v2 via REST API and here is the response received from the server.

HTTP/1.1 401 Unauthorized

Content-Type: application/vnd.com.nsn.cumulocity.error+json;charset=UTF-8 ;ver=0.9

{"error":"security/Unauthorized","message":"Failed to decode basic authentication token","info":"https://www.cumulocity.com/guides/reference/rest-implementation//#a-name-error-reporting-a-error-reporting"}

I have checked the decoded base64 code and it is correct. In this case, what else could be possible wrong?
