Enterprise API integration

APIs are contracts between teams. We design them to be stable, secure and understandable, and we build the integrations that use them.

What organizations bring us

APIs cause trouble when they are designed from the database outward, change without notice, expose more than the client needs or lack ownership. Consumers then build workarounds, and security reviewers find authorization gaps late.

Our approach is contract-first. The API is described in OpenAPI before code exists, reviewed by the teams who will call it, and tested against the contract in the pipeline. Authorization is designed per resource, not added at the end.

What the platform covers

  • Contract-first design

    OpenAPI definitions, naming, pagination, errors and examples agreed before build.

  • REST and GraphQL

    Style chosen by consumers and data shape, not preference.

  • Gateway and policies

    Authentication, throttling, quotas, caching and transformation at the edge.

  • Authentication and authorization

    OAuth 2.0 and OpenID Connect, scopes, and object-level checks in the service.

  • Versioning and lifecycle

    Deprecation policy, compatibility testing and consumer communication.

  • Event-driven integration

    Webhooks, queues and streams for systems that react to change.

  • Monitoring

    Latency, error rate, usage by consumer and alerting.

  • API security testing

    Authorization, business logic and abuse testing against the live design.

How an API program runs

  1. 1

    Inventory

    Find existing APIs and integrations, and who owns them.

  2. 2

    Define standards

    Naming, errors, security and versioning rules.

  3. 3

    Design contracts

    Write and review OpenAPI definitions with consumers.

  4. 4

    Build and test

    Contract tests, load tests and security tests in the pipeline.

  5. 5

    Publish and operate

    Documentation, onboarding, monitoring and support.

Questions people ask

REST or GraphQL?

REST for most service-to-service and partner APIs. GraphQL when many client types need different shapes of the same data. We explain the trade-offs.

Do you need an API gateway?

Once there are several APIs or external consumers, a gateway centralizes security and traffic rules. For one internal API it may be overhead.
