GetDataSourceIntrospection - Amazon AppSync
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

GetDataSourceIntrospection

Retrieves the record of an existing introspection. If the retrieval is successful, the result of the instrospection will also be returned. If the retrieval fails the operation, an error message will be returned instead.

Request Syntax

GET /datasources/introspections/introspectionId?includeModelsSDL=includeModelsSDL&maxResults=maxResults&nextToken=nextToken HTTP/1.1

URI Request Parameters

The request uses the following URI parameters.

includeModelsSDL

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.

Length Constraints: Minimum length of 1. Maximum length of 65536.

Pattern: [\\S]+

Request Body

The request does not have a request body.

Response Syntax

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

introspectionStatus

The status of the introspection during retrieval. By default, when a new instrospection is being retrieved, the status will be set to PROCESSING.

A FAILED operation will return an error and its details as an introspectionStatusDetail.

Type: String
