Custom API Integrations

What are custom API integrations?

Custom API integrations connect your existing systems — ERP, CRM, e-commerce platforms, accounting software — into a unified ecosystem. When applications "talk" to each other, data flows automatically, eliminating the need for manual entry across multiple systems.

European businesses often rely on a mix of international and local software. We build bridges between these systems, regardless of how different they are.

Types of integrations we develop

REST and GraphQL APIs — We build and consume modern APIs for real-time communication between systems. Whether you need to extract data from your ERP or automatically send orders to suppliers.

Webhooks and event-driven architecture — Your systems react instantly to events. A new order on WooCommerce? The invoice is automatically generated in your accounting system and stock is updated in the ERP.

Middleware and data transformation — When two systems use different formats, we build an intermediary layer that translates and validates data automatically.

Platform integrations — Direct experience with major European marketplace APIs, courier services, invoicing platforms, and government reporting systems.

Why does this matter for your business?

Elimination of manual data entry — Every minute spent copying data from one application to another is wasted time. Integrations completely remove this process.

Real-time data — Managers see automatically updated dashboards, not manually generated reports from employees.

Scalability — As your business grows, integrations grow with it. You no longer hire people just to move data between systems.

Our process

We start with a free technical audit of your systems. We identify available APIs, what data needs synchronizing, and the most efficient architecture. Then we build, test, and launch the integration — with complete documentation and support.

Security and compliance

All integrations are built with end-to-end encryption, OAuth 2.0 authentication, and comply with GDPR requirements. Your company data is protected at every stage.
