Get started

Function types, activation, and plan requirements

The five Function types you can create, how a rule goes live, what works on each Shopify plan, and the Shopify limits that apply to every store.

Discounts

Discount actions explained

What each discount action does, the three value modes (percentage, fixed amount off, fixed price), apply-to-first ordering, order discount scope, scheduling, and subscription handling.

Line groups: how a rule selects products

How Line groups select cart lines by product, variant, collection, tag, vendor, SKU, variant name, metafield, line item property, or selling plan, and how actions and conditions use them.

Payment and delivery customizations

Payment method names: match the internal name, not the checkout label

Payment customization rules match Shopify's internal gateway name, not the checkout label. How to find it, how contains and comma lists work, wallets, COD, and the US and Canada credit card limit.

Validation

Cart and checkout validation: what it can block and where the message shows

How validation rules block checkout, where the error appears, when they run, per-product quantity limits, tag-restricted products, and what the visual builder cannot compute.

Reference

Limits and budgets: Data limit, instructions, and output

The 10 KB configuration limit shown as Data limit, the ~11 million instruction budget, the ~20 KB output cap, the 25 active rule limits, and how to design around them.

What SMART Functions Creator does not do

An honest list: no gift auto-add, no code rejection messages, no storefront widgets, no order reports, no payment-type discounts, no billing address rules, no shipping profile control, no custom code execution.
