Hi all I’m stuck trying to build a custom private app that applies a free shipping discount whenever certain conditions are met, ie buy X get free shipping (currently free shipping can only be applied minimum purchase amount or minimum number of items so that is why I’m creating a custom private app).
Is there an easier free solution than creating a private app?
If not, would I use a graphql mutation on cart update using the storefront api?
Apologies I am a complete and utter noob. Any help would be appreciated.
