User ID in Cognito

I use AWS API Gateway + AWS Cognito (Federated Identity + User Pool). I'm creating REST API in API Gateway. There are methods for getting users list and for getting user by id. What should I use as user ID?

Response should contain te following user data: ID, username, first name, last name etc. Username, first name, last name are stored in User Pool attributes.

I see in examples that they use cognitoIdentityId as User ID. If I will use cognitoIdentityId as ID, then how should I get user data by this ID? Please give me an example or link to API reference how to get user data by cognitoIdentityId.

You should be able to get user attributes as shown in the following example using the Username.

var AWS = require('aws-sdk');
AWS.config.region = 'us-east-1'; //This is required to derive the endpoint
var poolData = { UserPoolId : 'us-east-1_TcoKGbf7n',
    ClientId : '4pe2usejqcdmhi0a25jp4b5sh3'
};
var userPool = new AWS.CognitoIdentityServiceProvider.CognitoUserPool(poolData);
var userData = { 
                Username : 'username',
                Pool : userPool
            };
var cognitoUser = new AWS.CognitoIdentityServiceProvider.CognitoUser(userData);

cognitoUser.getUserAttributes(function(err, result) {
    if (err) {
        alert(err);
        return;
    }
    for (i = 0; i < result.length; i++) {
        console.log('attribute ' + result[i].getName() + ' has value ' + result[i].getValue());
    }
});

Reference: Examples: Using the JavaScript SDK

If you need to query the user attributes using AccessToken, then use the following example.

var params = {
  AccessToken: 'STRING_VALUE' /* required */
};
cognitoidentityserviceprovider.getUser(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Reference: AWS JavaScript SDK GetUser

Note: Currently there is no support in both AWS JavaScript SDK and API to get the user attributes by UserId.
