The x_SHA2_Hash parameter in silent posts is now empty. A signature key had already been generated for these accounts. We are seeing this both in sandbox and production.</P><P>I regenerated the signature key in sandbox, and now the parameter is populated in the silent posts for initial payments created via AIM, but not for rebills of the ARB subscription.</P><P>Is anyone aware of any changes in the functionality of the SHA2 hash in silent posts since 2019? Is it necessary for me to pass some parameter in the XML&nbsp;ARBCreateSubscriptionRequest to cause an SHA2 hash to be generated?</P><P>Thanks</P> Fri, 20 Jan 2023 18:14:45 GMT johnrahm 2023-01-20T18:14:45Z https://community.developer.cybersource.com/t5/Integration-and-Testing/x-SHA2-Hash-Missing-for-Rebills/m-p/85517#M53792 <P>Hello Everyone,</P><P>We've recently noticed an issue in our Authorize.NET integration, which has worked fine for many years.
