Third-party integrations that hold up in production: payments, delivery platforms, cloud vendors.
We have integrated Adyen for a national retailer’s checkout (with payment-to-order status synchronization and transactional-consistency error handling), Uber Eats and Deliveroo for delivery, PayGreen for an in-house product, and Microsoft, AWS, Google Cloud, Bitnami and Zendesk on a marketplace platform. Integrations fail in the gaps: timeouts, duplicate webhooks, partial failures. That is exactly where we put the engineering: idempotency, retries, fallbacks and reconciliation.
Real API behaviour, rate limits, failure modes, sandbox quirks.
Mapping, validation, idempotency and fallback strategy.
Timeouts, duplicates and partial failures tested deliberately.
Monitoring and reconciliation jobs that catch drift before finance does.
Very likely. We have shipped Adyen and PayGreen in production; the reliability patterns transfer to any serious provider.
Retries with backoff, circuit breakers and fallbacks, designed per integration. Flakiness is assumed, not discovered.
Idempotency keys and dedup at the boundary. Every webhook handler we ship assumes it will be called twice.
Yes: error alerting and reconciliation reports, so silent drift between systems gets caught early.
