We used Sentry to isolate and resolve critical bugs at the checkout layer before they ever reached production. Its source map integrations and performance traces were especially useful when debugging stack traces from our headless merchant implementations.
They gave us deep insights into how our beta merchants and their customers interacted with each stage of our checkout funnel. Using event-based analytics, we were able to correlate drop-offs with specific card scheme selections and geo-IP anomalies.
Postman was critical in helping our engineering team run concurrent testing across multiple API endpoints under simulated transaction volumes. Its collection-level scripts and pre-request chaining helped us replicate real-world payment behaviors with near-perfect accuracy.
