Focus area: Applications and integration · API and integration

Interfacesthatremainclearlyexplainableyearslater.

We design and build APIs and integrations as contracts between systems. Data model, error model, versioning, and security are written down before implementation. The interface stays reliable for consumers even when something behind it changes.

Engagement packages

Every package starts from a clear objective.

Each package starts with a worked-out architecture and ends with a clean handover to your operations team, and we agree the scope and the investment frame together after a first inventory of the work at hand.

2 – 3 weeks

Start here

API audit

Assessment of the current interface landscape. We review contracts, versioning, security and audit mechanics, and deliver a consolidation recommendation.

Included

  • Inventory of existing interfaces
  • Assessment of contracts and versioning
  • Security and audit trails
  • Consolidation proposal
  • Risk picture for migrations

Best suited for

Organisations with a grown interface landscape that should be structurally cleaned up.

How we work

Our approach.

Every engagement follows a repeatable course from analysis through implementation into ongoing operation.

01

Contract

We define the API contract in writing: data model, error model, security and versioning model. Consumers can rely on it.

02

Architecture

We design the implementation: synchronous or event-driven, with or without caching, with or without multi-tenancy. The choice follows the load and consistency requirements.

03

Implementation

The interface is built with contract tests, observability, and sandbox. Consuming teams can connect early.

04

Handover

We hand over the contract, the sandbox, and the observability picture to your teams. Extensions follow a documented versioning path.

Typical use cases

Where this work carries the most weight.

A selection of typical engagements, without drawing a closed list, so requests beyond these areas are explicitly welcome.

An existing SOAP interface should be moved to REST or GraphQL.

A new API for partner integrations with versioning and audit path.

Event-driven integration between an ERP and an in-house development.

Consolidation of several integration paths into a unified mechanic.

Building a public developer API with documentation and sandbox.

Common questions

What decision-makers usually ask.

Answers to the questions we are asked most often during the framing of an engagement.

4 questions

We decide case by case. REST is the right answer when clear resource models and simple contracts are asked for. GraphQL fits when different consumers need different slices of data.
