An API Platform Your Partners Can Build On

We design and build enterprise API platforms — gateway infrastructure, developer portals, lifecycle management and governance for internal and partner-facing APIs.

THE CHALLENGE

APIs without a platform become unmanageable

Most enterprises start with a few APIs — internal, undocumented, built by individual teams. Over time, the number grows to dozens, then hundreds. Without a platform, there is no consistency: different authentication schemes, no versioning strategy, no usage visibility, no rate limiting. Developers cannot discover existing APIs, so they build new ones that duplicate functionality. Security teams cannot audit what is exposed. Partner onboarding takes weeks because every integration is custom.

An API platform brings order to this chaos. It provides a single gateway for all API traffic, a developer portal for discovery and onboarding, lifecycle management for versioning and deprecation, and analytics for usage and performance. It turns APIs from ad-hoc integrations into a managed, governed product.

OUR APPROACH
01

Strategy & Design

We define your API platform strategy — internal-only, partner-facing or public. We design the gateway architecture, security model, versioning strategy and governance policies.

02

Build & Deploy

We implement the API gateway, developer portal, CI/CD pipeline for API deployment and monitoring stack. Existing APIs are onboarded and standardized.

03

Govern & Scale

API lifecycle management, usage analytics, SLA monitoring and continuous optimization. We establish governance processes that scale as your API portfolio grows.

CAPABILITIES

What we deliver

API Gateway Infrastructure

Enterprise-grade API gateway deployment (Kong, Azure APIM, AWS API Gateway) with traffic management, security policies, rate limiting and request/response transformation.

Developer Portal

Self-service portal with interactive API documentation (Swagger/OpenAPI), sandbox environments, API key management, usage dashboards and onboarding workflows for internal and external developers.

API Lifecycle Management

Version management, deprecation policies, backward compatibility enforcement and automated contract testing. APIs are treated as products with defined lifecycle stages.

Security & Governance

OAuth 2.0, API key rotation, mutual TLS, IP whitelisting and WAF integration. Governance policies enforce naming conventions, error formats, pagination patterns and security standards.

Analytics & Monetization

Usage analytics, latency monitoring, error rate tracking and SLA reporting. For partner APIs, usage-based billing, quota management and tiered access plans.

PROJECT SPOTLIGHT
API PLATFORM

Arvato Turkey

CHALLENGE

Arvato Turkey had 80+ APIs across business units with no central management — inconsistent security, no discovery mechanism and partner onboarding taking 4-6 weeks per integration.

APPROACH

We deployed a centralized API platform with Kong gateway, a developer portal with self-service onboarding, standardized authentication and automated API documentation generation from OpenAPI specs.

RESULT

Partner onboarding reduced from 6 weeks to 3 days. All APIs governed under a single platform with consistent security, monitoring and versioning.

USE CASES

Where we apply it

  • Let internal teams discover and reuse APIs, not duplicate them
  • Onboard partners to your APIs in 3 days instead of 6 weeks
  • Consolidate all API traffic through a single governed gateway
  • Monetize your data assets through metered API access
  • Meet PSD2 and Open Banking API requirements on schedule

FAQ

Common questions about api platform development

Which API gateway should we use? +

It depends on your ecosystem. If you are primarily on Azure, Azure API Management is the natural choice. AWS-native organizations benefit from AWS API Gateway. For multi-cloud or vendor-neutral requirements, Kong provides maximum flexibility. We help you evaluate based on your specific needs — features, cost, team expertise and cloud strategy.

How do you handle API versioning? +

We implement URL-based versioning (v1, v2) for major changes and header-based versioning for minor changes. Backward compatibility is enforced through automated contract testing in the CI/CD pipeline. Deprecation follows a defined schedule with advance notice to consumers.

Can you migrate our existing APIs to the new platform? +

Yes. We onboard existing APIs to the platform by adding gateway routing, standardizing authentication, generating OpenAPI documentation and configuring monitoring. Most APIs can be onboarded without any code changes — only gateway configuration.

How long does it take to set up an API platform? +

A production-ready API platform with gateway, developer portal and CI/CD pipeline takes 6-8 weeks. Onboarding existing APIs runs in parallel — typically 5-10 APIs per week once the platform is established. Full enterprise rollout across all business units takes 3-6 months.
