A legacy .NET HttpHandler buried inside the customer portal was processing webhook callbacks synchronously — and at 20M+ messages a month, vendor retry storms inflated that to 75 million callbacks with 90-second processing latency. We replaced it with an Azure Function that acknowledges in milliseconds and routes to channel-isolated processors via Service Bus, dropping latency to sub-second and eliminating the retry cascade entirely.
