// Package cognitoidentity provides the client and types for making API
// requests to Amazon Cognito Identity.
//
// Amazon Cognito is a web service that delivers scoped temporary credentials
// to mobile devices and other untrusted environments. Amazon Cognito uniquely
// identifies a device and supplies the user with a consistent identity over
// the lifetime of an application.
//
// Using Amazon Cognito, you can enable authentication with one or more third-party
// identity providers (Facebook, Google, or Login with Amazon), and you can
// also choose to support unauthenticated access from your app. Cognito delivers
// a unique identifier for each user and acts as an OpenID token provider trusted
// by AWS Security Token Service (STS) to access temporary, limited-privilege
// AWS credentials.
//
// To provide end-user credentials, first make an unsigned call to GetId. If
// the end user is authenticated with one of the supported identity providers,
// set the Logins map with the identity provider token. GetId returns a unique
// identifier for the user.
//
// Next, make an unsigned call to GetCredentialsForIdentity. This call expects
// the same Logins map as the GetId call, as well as the IdentityID originally
// returned by GetId. Assuming your identity pool has been configured via the
// SetIdentityPoolRoles operation, GetCredentialsForIdentity will return AWS
// credentials for your use. If your pool has not been configured with SetIdentityPoolRoles,
// or if you want to follow legacy flow, make an unsigned call to GetOpenIdToken,
// which returns the OpenID token necessary to call STS and retrieve AWS credentials.
// This call expects the same Logins map as the GetId call, as well as the IdentityID
// originally returned by GetId. The token returned by GetOpenIdToken can be
// passed to the STS operation AssumeRoleWithWebIdentity (http://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRoleWithWebIdentity.html)
// to retrieve AWS credentials.
//
// If you want to use Amazon Cognito in an Android, iOS, or Unity application,
// you will probably want to make API calls via the AWS Mobile SDK. To learn
// more, see the AWS Mobile SDK Developer Guide (http://docs.aws.amazon.com/mobile/index.html).
//
// See https://docs.aws.amazon.com/goto/WebAPI/cognito-identity-2014-06-30 for more information on this service.
//
// See cognitoidentity package documentation for more information.

//
// Using the Client
//
// To use the client for Amazon Cognito Identity you will first need
// to create a new instance of it.
//
// When creating a client for an AWS service you'll first need to have a Session
// already created. The Session provides configuration that can be shared
// between multiple service clients. Additional configuration can be applied to
// the Session and service's client when they are constructed. The aws package's
// Config type contains several fields such as Region for the AWS Region the
// client should make API requests too. The optional Config value can be provided
// as the variadic argument for Sessions and client creation.
//
// Once the service's client is created you can use it to make API requests the
// AWS service. These clients are safe to use concurrently.
//
//   // Create a session to share configuration, and load external configuration.
//   sess := session.Must(session.NewSession())
//
//   // Create the service's client with the session.
//   svc := cognitoidentity.New(sess)
//
// See the SDK's documentation for more information on how to use service clients.
// https://docs.aws.amazon.com/sdk-for-go/api/
//
// See aws package's Config type for more information on configuration options.
// https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config
//
// See the Amazon Cognito Identity client CognitoIdentity for more
// information on creating the service's client.
// https://docs.aws.amazon.com/sdk-for-go/api/service/cognitoidentity/#New
//
// Once the client is created you can make an API request to the service.
// Each API method takes a input parameter, and returns the service response
// and an error.
//
// The API method will document which error codes the service can be returned
// by the operation if the service models the API operation's errors. These
// errors will also be available as const strings prefixed with "ErrCode".
//
//   result, err := svc.CreateIdentityPool(params)
//   if err != nil {
//       // Cast err to awserr.Error to handle specific error codes.
//       aerr, ok := err.(awserr.Error)
//       if ok && aerr.Code() == <error code to check for> {
//           // Specific error code handling
//       }
//       return err
//   }
//
//   fmt.Println("CreateIdentityPool result:")
//   fmt.Println(result)
//
// Using the Client with Context
//
// The service's client also provides methods to make API requests with a Context
// value. This allows you to control the timeout, and cancellation of pending
// requests. These methods also take request Option as variadic parameter to apply
// additional configuration to the API request.
//
//   ctx := context.Background()
//
//   result, err := svc.CreateIdentityPoolWithContext(ctx, params)
//
// See the request package documentation for more information on using Context pattern
// with the SDK.
