# WooCommerce payment gateway plugin base
This code can be used as a base to create your own simple custom payment gateway for WooCommerce. If not used in a custom plugin, you need to add this code to your child themes functions.php file or via a plugin that allows custom functions to be added, such as the [Code snippets](https://wordpress.org/plugins/code-snippets/) plugin. Please dont add custom code directly to your parent themes functions.php file as this will be wiped entirely when you update the theme.
``` php
