API-Led Connectivity

MuleSoft architectural approach organizing reusable APIs into System, Process and Experience layers.

Definition

System APIs unlock data from core systems, Process APIs orchestrate and compose business logic, and Experience APIs shape data for specific channels. Layering promotes reuse, decoupling and faster delivery compared with point-to-point integration.

Example

A mobile Experience API calls an Order Process API that combines SAP and Salesforce System APIs.

Exam tip

Questions often ask which layer a capability belongs in; channel-specific formatting is Experience, orchestration is Process.
