Getting Started with Shopify Functions

Shopify Functions allow you to create custom commerce logic that transforms how your store operates. With Sway Functions Generator, you can build these custom functions without writing a single line of code. This guide will help you understand what Shopify Functions are and how to implement them for your specific business needs.

What Are Shopify Functions?

Shopify Functions allow merchants to customize core commerce logic in four key areas:

1. Discounts - Create custom discount strategies beyond Shopify's native capabilities
2. Shipping - Customize how shipping options appear and are filtered at checkout
3. Payment - Control which payment methods are available and how they're displayed
4. Cart Validation - Create rules that validate cart contents before checkout

These customizations run directly on Shopify's infrastructure, ensuring fast performance even during high-traffic events.
