Hey @skmanoj322, I think there was a misunderstanding with the issue. This didn’t ask for a new webhook; we only want to add the cancellation reason to the existing cancel webhook's payload

Sorry about that! We’ll try to make it clearer next time. 🙏

[TusharBhatt1]

Thanks for the effort , closing this.
@skmanoj322 feel free to raise a new one with the approach @CarinaWolli mentioned above.
