Cognito User Pool API - Get user by sub / user ID / UUID

0

Hi, we want to integrate our service with Cognito user pools, where our data store uses the user ID as the primary key. However, I've learned that Cognito's AdminGetUser method retrieves users by their username. The only way that I'm able to query Cognito to retrieve a user's information by their user ID, is to use ListUsers with a filter for the specific user ID.

Is there really no way to retrieve a user's information by the user ID? If not, then our data store would need to store PII, or we would need to find some other workaround. We're looking to avoid these outcomes.

AWS Cognito doesn't have a direct method to retrieve user information using the user ID. The workarounds include using the ListUsers method with a filter for the specific user ID, or the GetUser method with an Access Token.

Hello, can you describe what you're looking to achieve in a little more detail? It sounds like you want to store only the the sub attribute for a user, and then be able to query their full details using that identifier. The sub attribute is the unique identifier for each user. This should be achievable using the ListUsers API together with the sub as a filter.

You describe this in your question, is there a reason this approach isn't sufficient?
