Amazon Cognito user invite


Hi Guys, I am trying to send invite email to a user with a link that user can click and enter password so that I can create user. Do I need to use Lambda for this? Any documentation will be helpful

You can create a new user the specified user pool through the Amazon Cognito API's. Refer here for the API details :

If you are using the AWS SDK, then the guidance on how to do this is here: (This is JS, you can browse for the SDK for the programming language of your choice)

For Lambda, as you've mentioned above, if you want to create an user - then the sample is as provided below,

const AWS = require('aws-sdk');

const userPoolId = 'YOUR_USER_POOL_ID';
const clientId = 'YOUR_APP_CLIENT_ID';
const region = 'YOUR_REGION';

const cognito = new AWS.CognitoIdentityServiceProvider({ region });

const params = {
  UserPoolId: userPoolId,
  Username: 'NEW_USER_USERNAME',
  DesiredDeliveryMediums: ['EMAIL'],
  UserAttributes: [
      Name: 'email',
      Value: 'NEW_USER_EMAIL',
      Name: 'name',
      Value: 'NEW_USER_NAME',
      Name: 'custom_attribute',
      Value: 'CUSTOM_VALUE',
  TemporaryPassword: 'TEMP_PASSWORD',
  MessageAction: 'SUPPRESS',

cognito.adminCreateUser(params, (err, data) => {
  if (err) {
    console.log(err, err.stack);
  } else {

Please refer and create the user pools and the necessary user attribute settings

Hope this helps
