resendConfirmationCode method
Resends the code that confirms a new account for a user who has signed up
in your user pool. Amazon Cognito sends confirmation codes to the user
attribute in the AutoVerifiedAttributes property of your user
pool. When you prompt new users for the confirmation code, include a
"Resend code" option that generates a call to this API operation.
If you have never used SMS text messages with Amazon Cognito or any other Amazon Web Services service, Amazon Simple Notification Service might place your account in the SMS sandbox. In sandbox mode , you can send messages only to verified phone numbers. After you test your app while in the sandbox environment, you can move out of the sandbox and into production. For more information, see SMS message settings for Amazon Cognito user pools in the Amazon Cognito Developer Guide.

Parameter clientId :
The ID of the user pool app client where the user signed up.
Parameter username :
The name of the user that you want to query or modify. The value of this
parameter is typically your user's username, but it can be any of their
alias attributes. If username isn't an alias attribute in
your user pool, this value must be the sub of a local user or
the username of a user from a third-party IdP.
Parameter analyticsMetadata :
Information that supports analytics outcomes with Amazon Pinpoint,
including the user's endpoint ID. The endpoint ID is a destination for
Amazon Pinpoint push notifications, for example a device identifier, email
address, or phone number.
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 Lambda functions to user pool triggers.
When Amazon Cognito invokes any of these functions, it passes a JSON
payload, which the function receives as input. This payload contains a
clientMetadata attribute that provides the data that you
assigned to the ClientMetadata parameter in your request. In your function
code, you can process the clientMetadata value to enhance
your workflow for your specific needs.
To review the Lambda trigger types that Amazon Cognito invokes at runtime with API requests, see Connecting API actions to Lambda triggers in the Amazon Cognito Developer Guide.
-
Store the
ClientMetadatavalue. 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, theClientMetadataparameter serves no purpose. -
Validate the
ClientMetadatavalue. -
Encrypt the
ClientMetadatavalue. Don't send sensitive information in this parameter.
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. For more information about SecretHash, see Computing
secret hash values.
Parameter userContextData :
Contextual data about your user session like the device fingerprint, IP
address, or location. Amazon Cognito threat protection evaluates the risk
of an authentication event based on the context that your app generates
and passes to Amazon Cognito when it makes API requests.
For more information, see Collecting data for threat protection in applications.
