Enterprise Integration

APIs and Integrations Designed for Change and Failure

Integrations fail at organizational boundaries: contracts evolve, credentials expire, callbacks arrive twice, dependencies slow down, and ownership becomes unclear. ARIN designs integration layers that make these realities explicit and operable.

Discuss Your Requirements

Contract-first interfaces

Define behavior before implementation and keep change safe for consumers.

✓REST, asynchronous event and webhook contracts
✓Schema validation and versioning
✓Authentication, authorization and rate limits
✓Consumer-driven and integration testing

Resilience patterns

Prevent one dependency from destabilizing a wider business journey.

✓Timeouts, bounded retries and circuit breakers
✓Idempotency and deduplication
✓Queues, dead letters and replay controls
✓Fallbacks and manual recovery paths

Integration visibility

Make failures discoverable by correlation ID, partner, business operation and outcome.

✓Structured logs, metrics and distributed traces
✓Partner dashboards and service-level indicators
✓Audit history and payload-safe diagnostics
✓Alerting tied to business impact

Frequently Asked Questions

Can ARIN integrate legacy applications without rewriting them?

Yes. Adapters and anti-corruption layers can expose stable contracts while containing legacy protocols and data models.

How are duplicate webhooks handled?

Webhook identity, database constraints, idempotent state transitions and replay-safe consumers ensure repeated delivery does not repeat the business action.

REST or Kafka—which should we use?

REST suits immediate request-response interactions; event streaming suits decoupled state propagation and replay. Many enterprise flows use both with explicit ownership.
