adminConfirmSignUp method

Future<void> adminConfirmSignUp({
  1. required String userPoolId,
  2. required String username,
  3. Map<String, String>? clientMetadata,
})

Confirms user registration as an admin without using a confirmation code. Works on any user.

Calling this action requires developer credentials.

May throw ResourceNotFoundException. May throw InvalidParameterException. May throw UnexpectedLambdaException. May throw UserLambdaValidationException. May throw NotAuthorizedException. May throw TooManyFailedAttemptsException. May throw InvalidLambdaResponseException. May throw TooManyRequestsException. May throw LimitExceededException. May throw UserNotFoundException. May throw InternalErrorException.

Parameter userPoolId : The user pool ID for which you want to confirm user registration.

Parameter username : The user name for which you want to confirm user registration.

Parameter clientMetadata : A map of custom key-value pairs that you can provide as input for any custom workflows that this action triggers.

If your user pool configuration includes triggers, the AdminConfirmSignUp API action invokes the AWS Lambda function that is specified for the post confirmation trigger. When Amazon Cognito invokes this function, it passes a JSON payload, which the function receives as input. In this payload, the clientMetadata attribute provides the data that you assigned to the ClientMetadata parameter in your AdminConfirmSignUp request. In your function code in AWS 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.

  • Amazon Cognito does not store the ClientMetadata value. This data is available only to AWS Lambda triggers that are assigned to a user pool to support custom workflows. If your user pool configuration does not include triggers, the ClientMetadata parameter serves no purpose.
  • Amazon Cognito does not validate the ClientMetadata value.
  • Amazon Cognito does not encrypt the the ClientMetadata value, so don't use it to provide sensitive information.
