I have a hybrid mobile app uses the AWS Javascript SDK to integrate with Amazon Cognito, using a Cognito user pool as the Identity Provider. It works.
I need to traverse the data using the AWS API to produce a report. A key part is listing which user (showing their username) is associated with which items (associated with their Cognito identity).
The Problem
I have a list of Cognito Identities from ListIdentities. I have a list of users in the Cognito User Pool from ListUsers. What links the Identity to the User?
I've tried...
This answer says the User's sub field is their IdentityId. Iterating through, no subs match any IdentityId values.
I thought the answer was in Cognito Identity's DescribeIdentity. This returns a map of Logins - which I expected to be an array of User IDs associated with this Identity. However it returns a map containing 1 URL (the URL of my User pool), which doesn't map to the user.
["Logins"]=>
array(1) {
[0]=>
string(55) "cognito-idp.eu-west-1.amazonaws.com/eu-west-1_*********"
}
How can I navigate the API from the Identity to the user, or vice versa?
