title: AWS Cognito: Test triggers using postman
body: <p>I am very new to AWS and I am trying to implement passwordless authentication. I have created an user pool and has implemented triggers for phone &amp; OTP authentication in AWS Cognito by following this tutorial: <a href="https://youtu.be/m8DE5ZV4FG4" rel="nofollow noreferrer">https://youtu.be/m8DE5ZV4FG4</a></p>
  <p>I created an user using the Hosted UI in the App Client Settings in AWS Cognito. But unfortunately I didn't receive any OTP in the number which was used to sign up. Is this the right way to test it? Is there a way to test the triggers without using AWS Amplify, for eg: by using another software like Postman?</p>
