Hi Justin. Thank you so much for your help! I tested it and it worked well. Is this problem usually happened with the sandbox accounts? We are using Sandbox accounts for system testing and later demonstrate it to other people. Should we move to a live productive account instead to get away of this issue? Thank you!

We had not checked it since July 10, but went back to it yesterday July 18 for the final testing after fixing the other parts of the system. We are not sure when was it happened.

Hello. Good day. The IPN, it worked very well for last few weeks, but today I have tried it many times again but got no response. I thought something wrong with the code in this site, but no, another testing site does not work too. I checked the IPN history and realized that there was no IPN generated. The last successfully generated was on July 10, 2022 (last week). Is there anyone facing the same problem? Please help! Thank you so much!
