Known Issues

REST API SDK Reduced Performance
 | EPS-33372

Description
There is a known issue that the Cybersource REST API SDK for .NET Standard can cause reduced performance or connection errors during periods of high transaction volume.
Audience
Merchants using the Cybersource REST API SDK for .NET Standard.
Technical Details
The SDK is creating new HTTPClient instances for every new transaction request. This can cause:
  • Increased DNS resolution overhead.
  • Lack of connection pooling.
  • Potential SocketException errors under heavy load, which occur during events such as the ballots sale.
The planned fix will update the SDK to reuse the created HTTPClient instance.
Workaround
There is no workaround for this issue.

Invalid Network Tokens in CAS Environment
 | EPS-34142

Description
There is a known issue that certain network tokens containing device PANs (DPANs) are invalid and unusable for testing in the CAS environment. The planned fix will result in the removal of the invalid network tokens to ensure accurate testing.
Audience
GPAP merchants using the CAS environment for testing network tokens with DPANs.
