cognitoidentityprovider_sign_up R Documentation

Registers the user in the specified user pool and creates a user name, password, and user attributes

Description

Registers the user in the specified user pool and creates a user name, password, and user attributes.

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.

This action might generate an SMS text message. Starting June 1, 2021, US telecom carriers require you to register an origination phone number before you can send SMS messages to US phone numbers. If you use SMS text messages in Amazon Cognito, you must register a phone number with Amazon Pinpoint. Amazon Cognito uses the registered number automatically. Otherwise, Amazon Cognito users who must receive SMS messages might not be able to sign up, activate their accounts, or sign in.

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.

Usage

cognitoidentityprovider_sign_up(ClientId, SecretHash, Username,
  Password, UserAttributes, ValidationData, AnalyticsMetadata,
  UserContextData, ClientMetadata)

Arguments

ClientId

[required] The ID of the 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.

Username

[required] The username of the user that you want to sign up. The value of this parameter is typically a username, but can be any alias attribute in your user pool.

Password

[required] The password of the user you want to register.

UserAttributes

An array of name-value pairs representing user attributes.

For custom attributes, you must prepend the ⁠custom:⁠ prefix to the attribute name.

ValidationData

Temporary user attributes that contribute to the outcomes of your pre sign-up Lambda trigger. This set of key-value pairs are for custom validation of information that you collect from your users but don't need to retain.

Your Lambda function can analyze this additional data and act on it. Your function might perform external API operations like logging user attributes and validation data to Amazon CloudWatch Logs. Validation data might also affect the response that your function returns to Amazon Cognito, like automatically confirming the user if they sign up from within your network.

For more information about the pre sign-up Lambda trigger, see Pre sign-up Lambda trigger.

AnalyticsMetadata

The Amazon Pinpoint analytics metadata that contributes to your metrics for 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.

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 SignUp API action, Amazon Cognito invokes any functions that are assigned to the following triggers: pre sign-up, custom message, and post confirmation. 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, which provides the data that you assigned to the ClientMetadata parameter in your SignUp 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.
