[Feature]: GraphQL support for API Platform

Please select the area the issue is related to

Gateway, Developer Portal, Platform API

Please select the aspect the issue is related to

Aspect/API (API backends, definitions, contracts, interfaces, OpenAPI), Aspect/UI (Frontend layouts, components, styling), Aspect/UX (User experience, flows, usability, clarity)

Suggested Feature

Currently, API Platform Gateway supports only REST APIs. To remain competitive and address diverse customer needs, it is essential to onboard support for other API types. GraphQL, being an emerging API standard and as it operates over existing transport protocols, must be implemented.

This will include;

• Support GraphQL as a first-class API type
• Allow creation of a GraphQL API similar to approaches used for REST APIs
• Provide QoS features for GraphQL
• API Console and API Portal support for GraphQL APIs
