Put the code onto a hosting service like heroku or glitch.
Go to the sellix dashboard, open up the developers module and click on webhook, add one. Firstly put the domain as https://yourdomain.com/api/getorder then set the event as order:paid
Go onto all your products, and on each of them add a custom field, set custom filed "Name" as "Discord ID" (THIS IS REQUIRED FOR THE AUTO-ROLE SYSTEM TO WORK)
