1. Create a new product and set the category to “WooCommerce Wallet Credit”.
2. Set the name you want.
3. Set the price that the customer pays.
4. Set “Wallet Credit”, which is the amount the user gets when they purchase the credit product.

Credit products are only used if the plugin is configured to use the predefined top-up amounts. If you set the plugin to allow customers to enter custom amounts, the credit products won’t be used.
