resendConfirmationCode method

Future<ResendConfirmationCodeResponse> resendConfirmationCode({ required String clientId, required String username, AnalyticsMetadataType? analyticsMetadata, Map<String, String>? clientMetadata, String? secretHash, UserContextDataType? userContextData, })

Resends the confirmation (for confirmation of registration) to a specific user in the user pool.

May throw ResourceNotFoundException. May throw InvalidParameterException. May throw UnexpectedLambdaException. May throw UserLambdaValidationException. May throw NotAuthorizedException. May throw InvalidLambdaResponseException. May throw TooManyRequestsException. May throw LimitExceededException. May throw InvalidSmsRoleAccessPolicyException. May throw InvalidSmsRoleTrustRelationshipException. May throw InvalidEmailRoleAccessPolicyException. May throw CodeDeliveryFailureException. May throw UserNotFoundException. May throw InternalErrorException.

Parameter clientId : The ID of the client associated with the user pool.

Parameter username : The user name of the user to whom you wish to resend a confirmation code.

Parameter analyticsMetadata : The Amazon Pinpoint analytics metadata for collecting metrics for ResendConfirmationCode calls.

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

You create custom workflows by assigning AWS Lambda functions to user pool triggers. When you use the ResendConfirmationCode 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 ResendConfirmationCode 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.

Parameter secretHash : A keyed-hash message authentication code (HMAC) calculated using the secret key of a user pool client and username plus the client ID in the message.

Parameter userContextData : Contextual data such as the user's device fingerprint, IP address, or location used for evaluating the risk of an unexpected event by Amazon Cognito advanced security.
