AWS CLI Command Reference

[ aws . cognito-idp ]

sign-up

Description

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

Note

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 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 .

Options

--client-id (string)

The ID of the client associated with the user pool.

--secret-hash (string)

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 (string)

The user name of the user you want to register.

--password (string)

The password of the user you want to register.

--user-attributes (list)

An array of name-value pairs representing user attributes.

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

(structure)

Specifies whether the attribute is standard or custom.

Name -> (string)

The name of the attribute.

Value -> (string)

The value of the attribute.

Shorthand Syntax:

Name=string,Value=string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Value": "string"
  }
  ...
]

--validation-data (list)

The validation data in the request to register a user.

(structure)

Specifies whether the attribute is standard or custom.

Name -> (string)

The name of the attribute.

Value -> (string)

The value of the attribute.

Shorthand Syntax:

Name=string,Value=string ...

JSON Syntax:

[
  {
    "Name": "string",
    "Value": "string"
  }
  ...
]

--analytics-metadata (structure)

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

AnalyticsEndpointId -> (string)

The endpoint ID.

Shorthand Syntax:

AnalyticsEndpointId=string

JSON Syntax:

{
  "AnalyticsEndpointId": "string"
}

--user-context-data (structure)

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.

IpAddress -> (string)

The source IP address of your user’s device.

EncodedData -> (string)

Encoded device-fingerprint details that your app collected with the Amazon Cognito context data collection library. For more information, see Adding user device and session data to API requests .

Shorthand Syntax:

IpAddress=string,EncodedData=string

JSON Syntax:

{
  "IpAddress": "string",
  "EncodedData": "string"
}

--client-metadata (map)

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 .

Note

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.

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.
