AWS SDK Version 3 for .NET
API Reference

AWS services or capabilities described in AWS Documentation may vary by region/location. Click Getting Started with Amazon AWS to see specific differences applicable to the China (Beijing) Region.

Registers (or retrieves) a Cognito IdentityId and an OpenID Connect token for a user authenticated by your backend authentication process. Supplying multiple logins will create an implicit linked account. You can only specify one developer provider as part of the Logins map, which is linked to the identity pool. The developer provider is the "domain" by which Cognito will refer to your users.

You can use GetOpenIdTokenForDeveloperIdentity to create a new identity and to link new logins (that is, user credentials issued by a public provider or developer provider) to an existing identity. When you want to create a new identity, the IdentityId should be null. When you want to associate a new login with an existing authenticated/unauthenticated identity, you can do so by providing the existing IdentityId. This API will create the identity in the specified IdentityPoolId.

You must use AWS Developer credentials to call this API.


For .NET Core, PCL and Unity this operation is only available in asynchronous form. Please refer to GetOpenIdTokenForDeveloperIdentityAsync.
