Checkout Gateflow

Checkout Gateflow runs if-then rules at checkout for shipping, payment, validation, and discounts. Hide or rename shipping and payment methods, block checkout with a custom message (for example P.O. Boxes), or offer a percentage off or free shipping. Match on country, province, cart total, quantity, address, company, customer tags, products, collections. Rules run as Shopify Functions—no theme embed. Use ready-made templates
