Integration Glossary

Anyone who wants to connect systems runs into many technical terms. Here we explain the most important ones in one or two sentences, with an everyday example and the difference from related terms.

Basics

  • Interface: connection through which two systems exchange data.
  • API: a system's defined programming interface.
  • Webhook: notification that a system sends immediately when an event occurs.
  • Data mapping: assignment of the fields of system A to system B.
  • Bidirectional integration: data exchange in both directions.

Architecture and tools

  • Middleware: intermediate layer between several systems.
  • iPaaS: cloud platform for connecting applications from building blocks.
  • Vendor lock-in: dependence on one provider that makes switching expensive.

  1. Hello! Which programs should talk to each other?
  2. Shopware and DATEV. We retype every invoice by hand.
  3. We connect them directly: invoices, credit notes and payments go to DATEV automatically as a Buchungsstapel (DATEV posting batch).
  4. What does it cost?
  5. After a 30-minute check, you get a fixed price within three working days. The code is yours.
