# SetUICustomization


Configures UI branding settings for domains with the hosted UI (classic) branding version. Your user pool must have a domain. Configure a domain with [CreateUserPoolDomain](API_CreateUserPoolDomain.md).

Set the default configuration for all clients with a `ClientId` of `ALL`. When the `ClientId` value is an app client ID, the settings you pass in this request apply to that app client and override the default `ALL` configuration.

This operation has no effect on managed login pages. To configure branding for domains with the managed login branding version, see [CreateManagedLoginBranding](API_CreateManagedLoginBranding.md).

**Note**  
Amazon Cognito evaluates AWS Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you must use IAM credentials to authorize requests, and you must grant yourself the corresponding IAM permission in a policy.
