# Overview

> How users earn and manage their flexibility rewards

During proposition configuration, we will agree with you the timing and magnitude of user rewards. We'll then handle
delivering those rewards to users.

## Paying users

Axle provides a complete payments solution to help users manage and withdraw their earnings. The system is built on Stripe and supports UK bank accounts.

### Balance and withdrawal URL

We generate a URL where your users can:

* View their rewards balance
* Link a UK bank account
* Withdraw earned rewards to their bank

### Optional: Transaction history

If you want to display transaction history directly in your application (rather than sending users to the payment portal), you can retrieve this data programmatically
via the [transaction history](/workflows/ev-charging/paying-users/transactions) endpoint.
