I’m using Amazon Cognito User pool to customize my UI for sign in and Log in.
From my understanding, Callback URL is the landing page after successful login.
When I tried to configure my callback URL, I always get below error
Trying to input call back URL as http://BUCKETName.s3-website-us-east-1.amazonaws.com/index.html

We were unable to update your App Configuration: http://BUCKETName.s3-website-us-east-1.amazonaws.com/index.html cannot use the HTTP protocol. (Service: AWSCognitoIdentityProviderService; Status Code: 400; Error Code: InvalidParameterException; Request ID: b3a888be-ded0-11e7-b16b-0fd6b04b4706)

If I replace this with http://localhost/ then it works but it’s of no use because can’t use it in production. Amazon documentation doesn’t provide much information on this. How do i make it work? Any idea?

Cognito call back url doesnt support http. you need to use https instead.
