May I ask what integration is not working? I didn't see any payment integration in your form so I assume it is different. If you are referring to the Google Integration then please try the following steps:
1. Remove the integration.
2. Log out from JotForm.
3. Close and re-open your browser.
4. Log back in to JotForm.
5. Add the integration again.
Please check if that works. Let us know if you're still having issues. Thank you.
