Bundle concepts - Knit

A Knit bundle is a merchandising offer: which products participate, when the offer applies, and what discount the shopper gets.

Selectors

Selectors decide which products are in the bundle.

Kind	Meaning
Product	One specific product
Collection	Products from a collection (single or multi)

Conditions and rewards

A condition is the rule the shopper must meet (for example, quantity 2).
A reward is what they get when the condition is met (for example, 19% off).
Conditions and rewards are grouped in condition sets. Each set is one tier, such as “Buy 2, save 19%”.

Knit does not send a precomputed bundle price. The widget (or your headless UI) maps condition sets to tiers, and a Shopify Discount Function applies the reward at checkout.

Bundle state

Only active bundles are returned by the storefront and headless APIs.
