Answer 1

Here is the solution.

Pre-requirement If you want to use the credential in aws-sdk (Manual Process) 1. Create IAM User and Assign a Cognito role to your user. 2. Generate Access Key and Secret Key for that user. 3. Use that Access Key and Secret Key in aws-sdk.

Like This,

let AWS = require("aws-sdk");
AWS.config.update({
    accessKeyId: "YOURKEY",
    secretAccessKey: "YOURSECRET",
    region: "YOURREGION"
});

Create object of CognitoIdentityServiceProvider class

const COGNITO_CLIENT = new AWS.CognitoIdentityServiceProvider({
  apiVersion: "2016-04-19",
  region: "us-east-1"
});


var poolData = {
    UserPoolId: "XXXXXXXXX",
    Username: "[email protected]",
    DesiredDeliveryMediums: ["EMAIL"],
    TemporaryPassword: "Abc@321",
    UserAttributes: [
      {
        Name: "email",
        Value: "[email protected]"
      },
      {
        Name: "email_verified",
        Value: "true"
      }
    ]
  };
  COGNITO_CLIENT.adminCreateUser(poolData, (error, data) => {
    console.log(error);
    console.log(data);
    callback(null, {
      statusCode: 200,
      body: JSON.stringify(data)
    });
  });

Or else you can directly assign IAM Role to your EC2 Instance in that case you do not need to set credentials in AWS.config Section.

Answer 2

And for AWS SDK v3 and ES6:

Install the Library

npm install @aws-sdk/client-cognito-identity-provider --save

Import the Module

import { CognitoIdentityProviderClient, AdminCreateUserCommand } from "@aws-sdk/client-cognito-identity-provider";

Create the Client

const cognitoClient = new CognitoIdentityProviderClient({ region: 'eu-west-1' });

Create the User

const command = new AdminCreateUserCommand({
      UserPoolId: USER_POOL_ID,
      Username: EMAIL_ADDRESS,
      DesiredDeliveryMediums: ['EMAIL'],
      TemporaryPassword: TEMPORARY_PASSWORD
    });

let response = await cognitoClient.send(command);

Note that you'll need to have cognito-idp:AdminCreateUser permission for this to work.
