Open API

important

Open API support was introduced in version 7.0 of the Genesis platform.

The Genesis low-code platform uses Open API to integrate with external systems.

Genesis makes this easy to configure and set up, and an Open API specification is generated for the following resources:

• Request Server
  • The specification is generated for every GPAL requestReply codeblock.
• Event Handler
  • The specification is generated for each GPAL eventHandler codeblock.
• Custom Endpoints
  • The specification is generated for each GPAL Custom Endpoints.
  • The standard specification can be augmented using the openapi { ... } DSL, described in our Advanced page.

Internally, the framework uses a metadata system to generate JSON schemas for input and return objects in the Open API spec. For more details, see our pages on Network messages - type-safe messages and metadata annotations.
