TIL Open Banking sandboxes are a trap compared to the real CDIC-insured API endpoints

Spent 3 months building on the Payments Canada sandbox in Toronto, then switched to the actual production test suite with a real credit union partner and found 5 integration bugs that would've killed our launch, anyone else hit this wall with the sandbox vs live data gap?

Yeah but what exactly was different? Like were the sandbox responses just too clean or was it the auth flow that broke?
