URI Request Parameters

The request uses the following URI parameters.

A boolean flag that determines whether SDL should be generated for introspected types or not. If set to true, each model will contain an sdl property that contains the SDL for that type. The SDL only contains the type data and no additional metadata or directives.

introspectionId

The introspection ID. Each introspection contains a unique ID that can be used to reference the instrospection record.

Required: Yes

maxResults

The maximum number of introspected types that will be returned in a single response.

Valid Range: Minimum value of 0. Maximum value of 25.

nextToken

Determines the number of types to be returned in a single response before paginating. This value is typically taken from nextToken value from the previous response.
