# Preset Amount Deposit

> Deposit a fixed, predetermined amount into a customer's balance

## Overview

A preset amount deposit lets you specify exactly how much the customer will deposit. The customer does not enter an amount — it is locked to the value you set. This is ideal when your platform offers predefined deposit tiers (e.g. $25, $50, \$100).

## How It Works

1. You create a checkout session with `type: "deposit"` 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 payment method and confirms.
4. Upon completion, a webhook is fired and the customer is redirected back to your app.
