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
None.
