Next conceptSpecification-driven design of reusable APIs

Explainer

In an application network, API implementations often call other APIs, so each implementation depends on the APIs it invokes, and those APIs may depend on others in turn. API-led connectivity organizes these dependency chains into System, Process and Experience layers. Each layer hides the complexity of the one below, so a change in a back-end system does not spread to every consumer.
Core information
  • The downstream service is the one making API requests, and the upstream service completes them. The terms describe the direction of dependency, not the direction of data. A downstream service that sends data in a POST request still depends on the upstream service to complete that request.
More details and nuances
  • Layering limits how far a change travels. Because each layer abstracts the layer below, an organization can switch a system of record, such as its core banking provider, without significant upstream or downstream impact. Old and new providers can also run side by side during the transition.
