-- Lists datasets for an identity. With Amazon Cognito Sync, each identity
-- has access only to its own data. Thus, the credentials used to make this
-- API call need to have access to the identity data.
--
-- ListDatasets can be called with temporary user credentials provided by
-- Cognito Identity or with developer credentials. You should use the
-- Cognito Identity credentials to make this API call.
