Collection triggers, step by step

Four triggers for collections: one for any update, three for the fields that matter for SEO and navigation. Collections have no tags in Shopify, which is why there are no tag triggers here.

On this page: Collection Update, Collection Title Changed, Collection Handle Changed, Collection Description Changed

Fires from	Shopify webhook
Permission	Product, Variant & Collection Data Access
