API & Integrations

It depends on your consumers. REST fits simple, cacheable, resource-based access and public partner APIs; GraphQL suits clients that fetch varied, nested data in one round trip and want to avoid over-fetching. We often run both behind the same gateway and help you pick per use case rather than by fashion.

Usually yes. We reverse-engineer behavior from their sandbox, capture real request and response traffic, and build a tested adapter around it. We also add monitoring so that if the provider silently changes a field or a status code, you find out before your customers do.

Every inbound event carries an ID we store and check before processing, so duplicate deliveries are dropped. Writes triggered by an event use idempotency keys as well, so even a retried delivery that slips past the check can't create a second charge or a duplicate record.

Yes. We commonly layer a clean, versioned API and a gateway in front of an existing system, exposing its data safely without touching the core. That gives you documented, rate-limited access for new clients and partners while the legacy code keeps running underneath.

Requests queue and retry with backoff rather than failing hard, and a circuit breaker stops hammering a dead provider. Writes that can't complete are held and reconciled once the provider recovers, so you don't lose data or leave an order in a broken half-paid state.
