Confirm Sign Up

cognitoidentityprovider_confirm_sign_up

R Documentation

This public API operation submits a code that Amazon Cognito sent to your user when they signed up in your user pool via the SignUp API operation

Description

This public API operation submits a code that Amazon Cognito sent to your user when they signed up in your user pool via the sign_up API operation. After your user enters their code, they confirm ownership of the email address or phone number that they provided, and their user account becomes active. Depending on your user pool configuration, your users will receive their confirmation code in an email or SMS message.

Local users who signed up in your user pool are the only type of user who can confirm sign-up with a code. Users who federate through an external identity provider (IdP) have already been confirmed by their IdP. Administrator-created users, users created with the admin_create_user API operation, confirm their accounts when they respond to their invitation email message and choose a password. They do not receive a confirmation code. Instead, they receive a temporary password.

Amazon Cognito doesn't evaluate Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you can't use IAM credentials to authorize requests, and you can't grant IAM permissions in policies. For more information about authorization models in Amazon Cognito, see Using the Amazon Cognito user pools API and user pool endpoints.

Usage

cognitoidentityprovider_confirm_sign_up(ClientId, SecretHash, Username,
  ConfirmationCode, ForceAliasCreation, AnalyticsMetadata,
  UserContextData, ClientMetadata, Session)

Arguments

ClientId

[required] The ID of the app client associated with the user pool.

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.

Username

[required] The username 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.

ConfirmationCode

[required] The confirmation code that your user pool sent in response to the sign_up request.

ForceAliasCreation

When true, forces user confirmation despite any existing aliases. Defaults to false. A value of true migrates the alias from an existing user to the new user if an existing user already has the phone number or email address as an alias.

Say, for example, that an existing user has an email attribute of bob@example.com and email is an alias in your user pool. If the new user also has an email of bob@example.com and your confirm_sign_up response sets ForceAliasCreation to true, the new user can sign in with a username of bob@example.com and the existing user can no longer do so.

If false and an attribute belongs to an existing alias, this request returns an AliasExistsException error.

For more information about sign-in aliases, see Customizing sign-in attributes.

AnalyticsMetadata

The Amazon Pinpoint analytics metadata for collecting metrics for confirm_sign_up calls.

UserContextData

Contextual data about your user session, such as the device fingerprint, IP address, or location. Amazon Cognito advanced security 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.

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 you use the ConfirmSignUp API action, Amazon Cognito invokes the function that is assigned to the post confirmation 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 ConfirmSignUp 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, note 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 send sensitive information in this parameter.

Session

The optional session ID from a sign_up API request. You can sign in a user directly from the sign-up process with the USER_AUTH authentication flow.

Value

A list with the following syntax:

list(
  Session = "string"
)

  ClientId = "string",
  SecretHash = "string",
  Username = "string",
