A GraphQL server can provide information about its schema. This functionality is called introspection and is achievable by sending an introspection query to the GraphQL server.

You may have seen GraphiQL or GraphQL Playgrounds providing a schema documentation and autocompletion. This is possible because those tools send a introspection query to the GraphQL server and use the response for providing those features.

When creating a GraphQL proxy in the Tyk Dashboard an introspection query is used to fetch the schema from the GraphQL upstream and display it in the schema tab.


When using a GraphQL proxy the introspection query is always sent to the GraphQL upstream. This means that changes in the Tyk schema won’t be reflected in the introspection response. You should keep the schemas synchronized to avoid confusion.

Introspection also works for the Universal Data Graph.
