OAUTH Client Authentication Failed in SAP P0 7.5 SP15

1405 Views

Hello Experts,

I'm facing the below error in REST Receiver channel (via OAUTH 2.0 Grant type).

Catching exception calling messaging system: com.sap.aii.adapter.rest.ejb.common.exception.HttpCallException: HTTP OAUTH 2.0 CLIENT CREDENTIALS GRANT call to https://url.com:443/api/authentication/access_token not successful.

Error while obtaining access token - response code: 400 response:

{

"error_description":"Client authentication failed",
"error":"invalid_request"
}:

Thanks and Regards,

Rajesh PS
