Connected by design

API & Systems Integration

Secure, observable integration across internal systems, SaaS platforms and external partners.

Typical problems

When the system needs deeper engineering.

  • 01Point-to-point integrations are becoming unmanageable
  • 02Data differs across systems with no clear source of truth
  • 03Partner APIs and webhooks fail unpredictably
  • 04Manual reconciliation is consuming operational time

What RKL delivers

A production-ready technical outcome.

  • ↳ API and event contracts
  • ↳ Integration and middleware services
  • ↳ OAuth and identity flows
  • ↳ Webhook ingestion and delivery
  • ↳ Data mapping and synchronisation
  • ↳ Retries, dead-letter handling and audit trails

Expected outcomes

  • ✓Reliable movement of business-critical data
  • ✓Lower coupling between platforms
  • ✓Failures are visible and recoverable
  • ✓New integrations follow consistent patterns

Delivery patterns

Architecture matched to the constraint.

PATTERN / 01

Anti-corruption layer

Protect internal models from the quirks and churn of external systems.

PATTERN / 02

Webhook gateway

Verify, store and process events asynchronously with replay support.

PATTERN / 03

Canonical data flow

Define ownership and mapping rules before synchronising records.

When to engage RKL

Bring us the difficult decision or delivery problem.

  • Several platforms must behave as one workflow
  • Existing integrations lose or duplicate data
  • A partner-facing API needs reliable governance

Questions

Service FAQ.

Can RKL integrate legacy systems?

Yes. We can introduce APIs, adapters, scheduled exchange or event capture according to the constraints of the existing system.

How do you handle failed synchronisation?

We design for idempotency, retry limits, dead-letter handling, audit history and operational replay rather than assuming every dependency is available.
