Overview

Integration quality decides whether financial systems can evolve. We design APIs and adapters with explicit contracts, versioning and operational behaviour, so new providers and products can be added without destabilising what already works.

Capabilities

  • REST APIs and webhooks, as implemented per engagement
  • OpenAPI documentation workflow
  • Versioning and deprecation policy
  • OAuth and service-identity patterns where deployed
  • Idempotency
  • Retry and back-off strategies
  • Monitoring and alerting
  • Integration test sandbox when available

Typical use cases

  • Exposing internal capabilities to partners
  • Wrapping legacy systems in modern interfaces
  • Connecting ERP and treasury systems to payment providers
  • Replacing point-to-point integrations with a governed layer

Security considerations

  • Authentication and authorisation per consumer
  • Rate limiting and quotas
  • Secrets in managed storage
  • Request logging without sensitive payloads

Security measures are design principles and implementation options; the controls in place depend on each deployment and its audits.
