API-Led Connectivity

An integration approach that structures APIs into three layers: System, Process, and Experience.

Complete Definition

API-Led Connectivity is an integration methodology (popularized by MuleSoft) that structures APIs into three layers: System APIs (connect to underlying systems), Process APIs (implement business logic), and Experience APIs (tailor data for specific user experiences). This approach promotes reusability, reduces point-to-point integrations, and creates a structured integration architecture.

Key Points

  • 1Three-layer architecture: System, Process, Experience
  • 2Promotes API reusability
  • 3Reduces integration complexity
  • 4Recommended for enterprise architectures
