# Automatic Top-Up

> Keep your wallet funded automatically so you never run out of credits during shipping operations.

Automatic top-up keeps your wallet balance funded without manual intervention. When your balance drops below a set threshold, the UniUni Platform automatically charges your default payment method and adds credits to your account.

This is especially useful if you're using the **REST API** or a fulfillment integration (Shopify, ShipStation, WooCommerce) where label printing happens in automated workflows — a low balance can cause label creation to fail mid-fulfillment.

## Enabling automatic top-up

1. Select your **profile icon** in the header bar.
2. Select **Settings** from the dropdown.
3. Navigate to the **Credits & Billing** tab.
4. Scroll to the **Automatic Top-Up** section.
5. Toggle **Auto Top-Up** to **ON**.
6. Set your **threshold** — the balance level at which an auto top-up is triggered.
7. Set your **top-up amount** — how much will be charged to your payment method when the threshold is reached.

Once enabled, top-ups happen automatically in the background. You can review all auto top-up charges in the [Transactions](/en/wallet/transactions) page.

<Note>
  The same processing fee applies to automatic top-ups. Set your top-up amount to **\$50.00 or more** to avoid the 2.9% + \$0.30 fee.
</Note>

## Disabling automatic top-up

Toggle **Auto Top-Up** to **OFF** at any time from the same **Credits & Billing** settings tab. Your configured threshold and top-up amount are saved for when you re-enable it.
