Empty page for the sign-up and sign-in pages hosted by AWS Cognito

Question

I have created the user pool and added new users to the user pool. My requirement is to use the default sign up/login page provided by cognito. So after retrieving the domain name for the hosted page it renders an empty page.

By simply entering the domain ends in several errors in the console. Appreciate if any one has identified the root cause for this.

Answer 1

If you simply add a /login to your existing URL you'll start to get useful error messages:

https://praedictio.auth.eu-west-1.amazoncognito.com/login

It's not documented very well, but your URL also requires some parameters:

• client_id - relates to the app for the identity provider.
• redirect_url - should match your redirect url from the UserPool app settings.
• response_type - token (or code).

 

https://praedictio.auth.eu-west-1.amazoncognito.com/login?response_type=code&client_id=(client_id)&redirect_uri=(encoded uri)

Answer 2

URL should be in the following format:

---

https://domain/login?response_type=code&client_id=client_id&redirect_uri=your_callback_url

---

Variables can be found in AWS > Amazon Cognito > User Pool > App Integration Tab

Domain:

Client ID of the App

Callback URL of the App

Pleaser refer Cognito document for more info.
