SetUICustomization - Amazon Cognito User Pools
Request SyntaxRequest ParametersResponse SyntaxResponse ElementsErrorsExamplesSee Also

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.

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.

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.
