With this operation, your users can update one or more of their attributes with their own credentials. You authorize this API request with the user's access token. To delete an attribute from your user, submit the attribute in your API request with a blank value. Custom attribute values in this request must include the custom: prefix.
See https://www.paws-r-sdk.com/docs/cognitoidentityprovider_update_user_attributes/ for full documentation.
cognitoidentityprovider_update_user_attributes(
UserAttributes,
AccessToken,
ClientMetadata = NULL
)[required] An array of name-value pairs representing user attributes.
For custom attributes, you must prepend the custom: prefix to the
attribute name.
If you have set an attribute to require verification before Amazon Cognito updates its value, this request doesn’t immediately update the value of that attribute. After your user receives and responds to a verification message to verify the new value, Amazon Cognito updates the attribute value. Your user can sign in and receive messages with the original attribute value until they verify the new value.
[required] A valid access token that Amazon Cognito issued to the user whose user attributes you want to update.
A map of custom key-value pairs that you can provide as input for any custom workflows that this action initiates.
You create custom workflows by assigning Lambda functions to user pool
triggers. When you use the UpdateUserAttributes API action, Amazon
Cognito invokes the function that is assigned to the custom message
trigger. When Amazon Cognito invokes this function, it passes a JSON
payload, which the function receives as input. This payload contains a
clientMetadata attribute, which provides the data that you assigned to
the ClientMetadata parameter in your UpdateUserAttributes request. In
your function code in Lambda, you can process the clientMetadata value
to enhance your workflow for your specific needs.
For more information, see Customizing user pool Workflows with Lambda Triggers in the Amazon Cognito Developer Guide.
When you use the ClientMetadata parameter, remember that Amazon Cognito won't do the following:
Store the ClientMetadata value. This data is available only to Lambda triggers that are assigned to a user pool to support custom workflows. If your user pool configuration doesn't include triggers, the ClientMetadata parameter serves no purpose.
Validate the ClientMetadata value.
Encrypt the ClientMetadata value. Don't use Amazon Cognito to provide sensitive information.
