# Preset Amount Withdrawal

> Withdraw a fixed, predetermined amount from the customer's balance

## Overview

A preset amount withdrawal lets you specify exactly how much the customer will withdraw. The amount is locked — the customer simply confirms and selects a payout method. This is ideal when you've pre-approved a withdrawal or are offering fixed cashout tiers.

## How It Works

1. You create a checkout session with `type: "withdrawal"` and include `fixed_amount_cents`.
2. The customer is redirected to the Soap-hosted checkout page with the amount pre-filled and locked.
3. The customer selects a payout method and confirms.
4. Upon completion, a webhook is fired and the customer is redirected back to your app.
