AdminConfirmSignUp

Confirms user sign-up as an administrator.

Unlike ConfirmSignUp, your IAM credentials authorize this operation to confirm user accounts. No confirmation code is required.

This request sets a user account active in a user pool that requires confirmation of new user accounts before they can sign in. You can configure your user pool to not send confirmation codes to new users and instead confirm them with this API operation on the back end.

Note

Amazon Cognito evaluates AWS Identity and Access Management (IAM) policies in requests for this API operation. For this operation, you must use IAM credentials to authorize requests, and you must grant yourself the corresponding IAM permission in a policy.

To configure your user pool to require administrative confirmation of users, set AllowAdminCreateUserOnly to true in a CreateUserPool or UpdateUserPool request.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

ClientMetadata

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

If your user pool configuration includes triggers, the AdminConfirmSignUp API action invokes the AWS Lambda function that is specified for the post confirmation trigger. When Amazon Cognito invokes this function, it passes a JSON payload, which the function receives as input. In this payload, the clientMetadata attribute provides the data that you assigned to the ClientMetadata parameter in your AdminConfirmSignUp 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 Using Lambda triggers in the Amazon Cognito Developer Guide.

Note

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 AWS 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.
