Integration & APIs

Design robust integrations between applications, vendors and partners: TM Forum Open APIs, REST, SOAP, events, resilience and security.

The challenge

Integration is where you find out whether an architecture holds. Several vendors, protocols from different generations, teams that do not share the same environments. We describe the interfaces, coordinate the parties and prove the whole thing works before go-live.

What we often see

  • Several vendors, and nobody clearly responsible for integration
  • Poorly described interfaces whose defects show up in testing
  • Point-to-point integrations that can no longer be changed
  • Silent errors: a message is lost and nobody notices

Our approach

  1. 1

    Contract the interfaces

    Every exchange described by its contract: data, statuses, errors, volumes, security, with a named owner.

  2. 2

    Pick the right style

    Synchronous APIs, events or batch exchanges, chosen for the business need rather than out of habit.

  3. 3

    Plan for failure

    Retries, idempotency, dead-letter queues and replay: resilience is designed in, not bolted on.

  4. 4

    Make it visible

    Traces and correlation identifiers to follow an exchange end to end in operation.

Skills we bring

  • Integration architecture and pattern selection
  • TM Forum Open APIs, REST, SOAP, ESB/EAI
  • Event-driven architecture and hybrid integrations
  • Interoperability between vendors, partners and legacy systems
  • Exchange security, observability and resilience
  • Error handling, retries and message replay
  • Test strategy: integration, end to end, UAT, VSR
  • Multi-vendor technical coordination

Typical deliverables

  • Integration plan
  • Interface repository and contracts
  • Test plans and reports
  • Go-live file

What you gain

  • Interface defects found in testing, not in production
  • Integrations you can change without retesting everything
  • Faster incident diagnosis thanks to traceability
