# Transaction Approval Using Email

This activity shows you how to create a transaction approval MFA authentication flow using a `request` token to encode the request parameters in a signed JWT.

The following operations are supported by the PingOne APIs:

* Create an application.

* Create a sign-on policy.

* Create an Email sign-on policy action.

* Create a device authentication policy.

* Create a user.

* Initiate an authorize request using a `request` token.

* Use the OTP check to complete the MFA action.

## Prerequisites

Get an access token from the worker application that you created in [Create an admin Worker app connection](../../../getting-started/create-an-admin-worker-app/index.html). To get a token from a different worker application in an alternate sandbox environment, run the token request endpoint using the client ID and client secret of your chosen worker app to authenticate the request. For more information, refer to [Get a PingOne admin access token](../../../getting-started/create-a-test-environment/step-1-get-access-token.html).
