It's super simple so let's get into it straight away.
Storefront URL
Head to your storefront from you main navigation menu
Click 'Edit Storefront'
Edit your storefront's URL
Replace any links on socials or marketing with the new URL.
E.g.
Program URLs
Each and every one of your programs can have its own custom URL. Here's how:
Head into your program once it's published
Click into the settings tab:
Edit your program's URL
Replace any links on socials or marketing with the new URL.
That's it. Remember if you make any changes to your URLs you will need to update the links used elsewhere.
Thanks
