Definition
In MuleSoft's API-led connectivity approach (part of the Salesforce ecosystem), a middle-tier API that orchestrates data between system APIs and experience APIs, handling business logic, data transformation, and process coordination.
Real-World Example
Consider a scenario where the Salesforce admin at FreshStart Inc. is working with Process API to automate a multi-step process that previously required three different people to complete manually. Process API now handles the entire sequence in seconds, sending notifications at each step and logging every action for audit purposes.
Why Process API Matters
In MuleSoft's API-led connectivity approach (part of the Salesforce ecosystem), a Process API is a middle-tier API that orchestrates data between system APIs and experience APIs, handling business logic, data transformation, and process coordination. The three-tier model includes System APIs (raw data access from individual systems), Process APIs (business logic and orchestration), and Experience APIs (channel-specific data delivery), with Process APIs serving as the integration glue.
Process APIs are valuable because they encapsulate business logic that would otherwise be duplicated across consumers. Multiple Experience APIs can call the same Process API for shared business logic, ensuring consistency and reducing duplication. Mature MuleSoft architectures invest in Process API design carefully, treating them as the layer where business rules and data transformation logic live. This separation of concerns is core to API-led connectivity's value proposition.
How Organizations Use Process API
- •TerraForm Tech — Built process APIs that orchestrate data from multiple system APIs into unified business views consumed by experience APIs.
- •Quantum Labs — Uses process APIs to encapsulate business logic, ensuring multiple experience APIs share the same consistent rules.
- •CodeBridge — Treats process API design as core architecture work in MuleSoft deployments.
