Has anyone else received this error message after generating a Transaction Key in CyberSource and inputting it into the Shopify "Payment Providers" back-end?Error: "wsse:FailedCheck: Security Data : UsernameToken authentication failed."
Yes. Currently getting.
I am interested in this as well... I am about to do this integration for a large client and cannot have this error.
I found this on the interwebs...
Are you using a test account or live production account and are youusing the correct corresponding gateway mode? Make sure your gateway is in test mode.
That is what i found too. i am waiting on a sandbox account and will try that and report back.
