Definition
In MuleSoft's API-led connectivity approach (part of the Salesforce ecosystem), an API layer that exposes data tailored to specific user experiences or channels, sitting above process and system APIs.
Real-World Example
a CRM manager at Summit Group uses Experience API to centralize important business data in one place. With Experience API configured to match their workflow, the team can quickly find relevant information, track changes over time, and generate reports that drive strategic decisions.
Why Experience API Matters
An Experience API is the top layer in MuleSoft's API-led connectivity approach, sitting above Process APIs and System APIs. Its job is to expose data in a shape tailored to a specific user experience or channel: a mobile app, a web portal, a partner integration, a third-party developer. Rather than each consumer having to navigate the underlying complexity of source systems, the Experience API presents a consumer-specific view that matches what that consumer actually needs.
API-led connectivity is about layering: System APIs unlock data from source systems, Process APIs orchestrate business logic across multiple systems, and Experience APIs deliver experience-specific representations to consumers. Without this layering, organizations end up with point-to-point integrations that become unmaintainable as they grow. With it, each layer serves a specific purpose and changes in one layer don't ripple through the others. Experience APIs are typically the most numerous and most short-lived: they evolve as user experiences change, while the underlying System APIs remain stable.
How Organizations Use Experience API
- •TerraForm Tech — Built separate Experience APIs for their mobile app, their web portal, and their partner integration. Each surfaces the same underlying data in the shape that its consumer needs.
- •CodeBridge — Refactored their integration architecture to use API-led layering after years of point-to-point integrations became unmaintainable. The Experience API layer absorbs consumer-specific changes.
- •Quantum Labs — Treats Experience APIs as the most volatile layer, expecting them to evolve as user experiences change while keeping System and Process APIs stable.
