The Payment Pages 2.0 sample code suite on Zuora GitHub site contains sample code and a ReadMe file for implementing Payment Pages 2.0.
Zuora Global Support does not troubleshoot content from GitHub. The sample code is as an example of code that has worked for previous implementations and was created by both Zuora and non-Zuora authors. You must customize the sample code for use with your system.
