13. Sign in to your AWS account to save the SSO configuration.

Creating Issuer URL

The issuer URL is not provided by AWS and needs to be created according to this rule:

https://cognito-idp.$ZONE.amazonaws.com/$POOLID

Where:

• $ZONE – the availability zone in which the user pool was added. Example: eu-north-1
• $POOLID – the User pool ID displayed on the pool's main page in AWS. Example: eu-north-1_WsvGfh1a9

Example issuer URL: https://cognito-idp.eu-north-1.amazonaws.com/eu-north-1_WsvGfh1a9
