API Reference (API Version 2016-04-18)

SetUICustomization

Sets the UI customization information for a user pool's built-in app UI.

You can specify app UI customization settings for a single client (with a specific clientId) or for all clients (by setting the clientId to ALL). If you specify ALL, the default configuration will be used for every client that has no UI customization set previously. If you specify UI customization settings for a particular client, it will no longer fall back to the ALL configuration.

Note

To use this API, your user pool must have a domain associated with it. Otherwise, there is no place to host the app's pages, and the service will throw an error.
