Legacy Scripts to Shopify Functions

Start by understanding the migration goal: replicate the features of your existing scripts with Shopify Functions. Begin by identifying all active legacy scripts in your store, and determine their use cases, such as discounts, payment methods, or shipping configurations.

Function Templates

Shopify offers pre-built function templates to speed up development. These templates are highly customizable, providing a foundation for creating tailored solutions. Select a template that closely matches the functionality of your legacy script.

Main Screen Overview

The main Shopify Functions interface is intuitive, offering a centralized dashboard for managing all created functions.

• Navigate to the Functions section in your Shopify admin.
• Explore existing examples and documentation to familiarize yourself with the interface.

Creating a Discount Function

Creating discount functions is one of the most common tasks when migrating from scripts. Follow these steps:

1. Select the discount template.
2. Name your function to reflect its purpose. For example, “Seasonal Discount.”
3. Define the trigger conditions for applying the discount.

Function Qualifiers

Shopify Functions support function qualifiers, allowing you to specify rules and conditions for applying a function.

• Example: Set qualifiers like “Cart Value over $100” or “Customer Tag: VIP.”
• Test multiple scenarios to ensure the qualifiers align with your business rules.

Discount Configuration

The discount configuration stage allows for detailed customization, such as defining percentage-based, fixed-value, or free shipping discounts.

Discount Type

Choose the discount type based on your store’s requirements:

• Percentage-based discounts: E.g., “10% off on orders over $50.”
• Fixed-value discounts: E.g., “$20 off for first-time buyers.”
• Free Shipping: E.g., “Free shipping for orders above $100.”

Message and Maximum Discounts

Add clear messaging to inform customers of active discounts. Define maximum discounts per order to prevent overuse or abuse.

• Example: “Maximum Discount: $50 per transaction.”

Discount Limits

You can establish usage limits, like:

• Limiting discounts to specific customer groups.
• Setting expiration dates.
• We will restrict the number of times a discount can be used.

Automatic vs Code Discount

Decide whether to apply the discount automatically or require a promotional code.

• Automatic Discounts: Great for site-wide promotions.
• Code Discounts: Ideal for tracking campaigns or exclusive offers.

Testing the Function

Before deploying, rigorously test your function.

• Use Shopify’s built-in testing tools to simulate real-world scenarios.
• Check edge cases and unexpected inputs to ensure reliability.

Debugging

If any issues arise during testing, leverage Shopify’s debugging tools. Debugging logs help identify errors or misconfiguration, ensuring smooth functionality post-launch.

Payment and Shipping Functions

Beyond discounts, Shopify Functions support customization of payment and shipping methods.

• Payment Functions: Modify payment workflows, introduce custom payment gateways, or implement dynamic payment rules.
• Shipping Functions: Adjust rates based on customer location, cart value, or product type.

Customizing Payment Methods

For payment methods, Shopify Functions allow you to:

• Set dynamic payment gateways based on customer location or cart value.
• Offer specific gateways during promotional periods.
