Enterprise API Platform
Enterprise API Platform
Enterprise API Platform

An enterprise API platform bundles the interfaces of many internal systems behind one central gateway and governs access, identity (OAuth 2.0, SSO), usage limits, versions and documentation consistently for internal teams and external partners.

We build robust enterprise APIs that seamlessly connect your systems. With RESTful design, GraphQL, Webhooks, and OAuth 2.0, we create secure, scalable interfaces that automate your data flows and simplify your IT landscape.

Who it's for

A fit if many systems, teams and partners in your company use interfaces and nobody keeps track of who accesses what. Typical for IT leads and architecture teams who want to govern access, security and versions centrally and offer partners a developer portal.

(01)How do you ensure API security?
We implement multiple security layers: OAuth 2.0 and API key authentication, JWT token management, TLS 1.3 encryption for all communications, rate limiting to prevent abuse, IP whitelisting options, and comprehensive audit logging. All APIs undergo security testing and comply with OWASP API Security Top 10. For enterprise clients, we support SAML SSO integration and custom security requirements.
(02)How is API versioning handled?
We version via the URL path or headers (v1, v2 …). Breaking changes only come in a new major version; how long the old version keeps running in parallel and how much advance notice is given, we define with you in a versioning policy. On top come detailed migration guides and a parallel operation period in which both versions run at the same time.
(03)What documentation do we receive?
You receive comprehensive API documentation including complete OpenAPI/Swagger specifications, interactive API explorer for testing endpoints, code examples in multiple languages (JavaScript, Python, Java, C#), detailed authentication guides, webhook integration documentation, error code reference, and rate limiting guidelines. Plus video tutorials for your development team and a dedicated onboarding session.
(04)How do you handle breaking changes?
Breaking changes follow a fixed governance process: deprecation notice with an agreed lead time via email and Deprecation and Sunset headers, detailed migration documentation with code examples, new version released in parallel (no forced upgrades), a fixed point of contact during the migration period, and automated compatibility tests. We plan the transition with a gradual rollout so that it runs without downtime.
(05)What about monitoring and observability?
Every API includes enterprise-grade monitoring: real-time performance metrics (latency, throughput, error rates), distributed tracing for request flows, custom dashboards with business-relevant KPIs, automated alerting for anomalies, detailed logging with correlation IDs, and API health checks. You get access to Grafana/Datadog dashboards and can integrate with your existing monitoring stack via webhooks or API.
(06)How is the API tested before go-live?
We follow a comprehensive testing strategy: unit tests for all endpoints (a target we measure together in the project: 90%+ coverage), integration tests with dependent systems, load testing to verify performance under expected traffic (a target we measure together in the project: up to three times peak load), security penetration testing, contract testing to ensure compatibility, and chaos engineering to test resilience. You receive a dedicated staging environment that mirrors production for your own testing, plus a sandbox with mock data for parallel development.
(07)How does the enterprise API platform differ from API development and tool integration?
The API platform is the control layer for many interfaces: one gateway for many internal systems and partners, with OAuth and SSO, rate limits, a developer portal and governance rules. If you need a single new interface for your product or data, API development is the right service. If you only want to connect existing tools, tool integration with Make, n8n or webhooks is enough. We place your project in the first call.
(08)How long does it take to build the API platform?
A well-defined slice, such as the gateway with the first connections, typically fits into a sprint of about four weeks. We plan the full platform with several existing systems as a build after scoping, usually 6–12 weeks. We provide sandbox environments for parallel development and testing.
(09)What level of support do you provide?
From final delivery we fix bugs free of charge for 30 days. For ongoing operations there is the Build & Support format with monitoring, a fixed communication channel and regular reviews. We agree availability and response times in the contract.
