callbackUrls

A list of allowed redirect, or callback, URLs for managed login authentication. These URLs are the paths where you want to send your users' browsers after they complete authentication with managed login or a third-party IdP. Typically, callback URLs are the home of an application that uses OAuth or OIDC libraries to process authentication outcomes. A redirect URI must meet the following requirements:

• Be an absolute URI.

• Be registered with the authorization server. Amazon Cognito doesn't accept authorization requests with redirect_uri values that aren't in the list of CallbackURLs that you provide in this parameter.

• Not include a fragment component. See OAuth 2.0 - Redirection Endpoint . Amazon Cognito requires HTTPS over HTTP except for http://localhost for testing purposes only. App callback URLs such as myapp://example are also supported.
