How to use “NPUSWC Client” – WooCommerce Shop
You do not need to setup something special for that because it is the client library which is independant from “Package Update Server for WooCommerce”. Just keep the plugin active and make sure if customers can get purchased tokens in My Account page.
Normally the page will be setup when you activate the plugin but if the page doesn not appear for some reason, go to “WooCommerce” -> “Settings” -> “Advanced”, you will see “Download Tokens” with the value “npuswc-tokens”, then press the button “Save the changes”.
This is how to setup endpoint for “Download Tokens” in My Accout page where customers can get the purchased tokens.
