update_managed_login_branding#

CognitoIdentityProvider.Client.update_managed_login_branding(**kwargs)#

Configures the branding settings for a user pool style. This operation is the programmatic option for the configuration of a style in the branding designer.

Provides values for UI customization in a Settings JSON object and image files in an Assets array.

This operation has a 2-megabyte request-size limit and include the CSS settings and image assets for your app client. Your branding settings might exceed 2MB in size. Amazon Cognito doesn’t require that you pass all parameters in one request and preserves existing style settings that you don’t specify. If your request is larger than 2MB, separate it into multiple requests, each with a size smaller than the limit.

As a best practice, modify the output of DescribeManagedLoginBrandingByClient into the request parameters for this operation. To get all settings, set ReturnMergedResources to true. For more information, see API and SDK operations for managed login branding

Note

Amazon Cognito evaluates 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.
