OpenAPI Specification

Verification Of Payee Requester Service API

Exposing the OpenAPI Specification Endpoint

The below should only ever be configured in development/test environments

By default, the OpenAPI specification UI endpoint is not enabled in the application. This can be enabled by setting the following properties in the application configuration:

springdoc.api-docs.enabled = true

spring.web.resources.static-locations = "classpath:/static/"

With the above properties set, the OpenAPI specification will be accessible by hitting the /swagger-ui/index.html path of the running application.
