Fund Your Account Balance

Once you’ve activated ShipStation Carriers, you’ll need to add funds to your account balance to start purchasing labels.

This article explains how to add funds to your ShipStation API account balance programmatically using the PUT method with the add_funds endpoint.

To learn how to add funds to your account balance via the ShipStation API dashboard, see the Add Funds section of our ShipStation Carriers help article.

Requirements

The carrier_id property for one of your ShipStation carriers.
The currency and amount properties. Currently, all ShipStation API transactions are in US Dollars (USD) or British Pounds (GBP) only.
The add_funds endpoint must first be enabled by the ShipStation API Support team. If you'd like to add funds via this endpoint, submit a request with our support team.

Check Your Balance

You can check your balance for a particular carrier using the List Carriers endpoint. For any carrier account where requires_funded_amount is set to true, you can add funds.

Fund Balances for Stamps.com or Endicia Standalone Accounts

If you have connected a standalone Stamps.com or Endicia account, you can use the same endpoint to fund those account balances as well. Simply use the corresponding carrier_id to indicate which balance you want to fund.
