How to Use Shopify Scripts to Automate Custom Checkout Rules

Introduction to Shopify Scripts

Shopify Scripts are small pieces of Ruby code that allow you to customize your store's checkout experience. They run on Shopify's servers and can modify line items, shipping rates, payment options, and more. With scripts, you can implement complex business rules without needing a custom app. This guide will show you how to use Shopify Scripts to automate custom checkout rules, especially focusing on hiding or showing payment methods based on location or cart contents.

Why Use Shopify Scripts for Checkout Automation?

Checkout automation with Shopify Scripts helps you create a tailored buying experience. You can enforce minimum order amounts, offer discounts, restrict shipping methods, and dynamically display payment options. This reduces cart abandonment and improves customer satisfaction. For example, you might want to hide cash on delivery for orders above a certain value, or show PayPal only for customers from specific countries.

Prerequisites

To use Shopify Scripts, you need a Shopify Plus plan. Scripts are not available on Basic, Shopify, or Advanced plans. You'll also need basic knowledge of Ruby syntax and access to the Script Editor in your Shopify admin.

Getting Started with the Script Editor

Go to your Shopify admin, navigate to Apps, and open the Script Editor. If you haven't installed it, you can add it from the Shopify App Store. The Script Editor provides a code editor and a console for testing. You can create new scripts or edit existing ones. Scripts are organized by type: Line Item Scripts, Shipping Scripts, and Payment Scripts.

Creating a Payment Script to Hide Payment Methods

Step 1: Understand the Input

Payment scripts receive an array of payment methods and a hash of cart information. You can filter the array based on conditions like cart total, customer location, or line item properties.

Step 2: Write the Script

Here's a simple script that hides a payment method called 'Cash on Delivery' if the cart total is over $100:

# Hide cash on delivery for orders over $100
if Input.cart.total_price.cents > 10000
  Input.payment_methods.delete_if { |pm| pm.name == 'Cash on Delivery' }
end
Output.payment_methods = Input.payment_methods

Step 3: Test and Deploy

Use the console to simulate carts. Once satisfied, click 'Save' and then 'Deploy'. The script will run on every checkout.

Hiding Payment Methods Based on Location

To hide payment methods based on customer location, you can access the shipping address from the cart. For example, to hide 'Bank Transfer' for customers outside the US:

# Hide bank transfer for non-US customers
if Input.cart.shipping_address.country_code != 'US'
  Input.payment_methods.delete_if { |pm| pm.name == 'Bank Transfer' }
end
Output.payment_methods = Input.payment_methods

Hiding Payment Methods Based on Cart Items

You can also check for specific product types or tags. For instance, hide 'PayPal' if the cart contains a product with the tag 'restricted':

# Hide PayPal if cart contains a restricted item
restricted = Input.cart.line_items.any? { |item| item.variant.product.tags.include?('restricted') }
if restricted
  Input.payment_methods.delete_if { |pm| pm.name == 'PayPal' }
end
Output.payment_methods = Input.payment_methods

Using Pre-Built Shopify Scripts

If you're not comfortable writing Ruby, you can use pre-built scripts from the Shopify Scripts library or third-party providers. These are ready-to-deploy snippets that you can customize with simple parameters. For example, a script to 'Hide Payment Methods by Country' might require you to enter a list of countries and payment methods.

Best Practices for Shopify Scripts

• Always test scripts in a development store before deploying to production.
• Keep scripts simple and efficient to avoid slowing down checkout.
• Use meaningful comments to document your logic.
• Monitor script performance via Shopify's logs.
• Regularly review scripts to ensure they still align with your business rules.

Common Use Cases for Checkout Automation

• Hide payment methods based on order total or weight.
• Show alternative payment methods for VIP customers.
• Restrict certain payment methods to specific shipping zones.
• Automatically apply discounts based on cart contents.
• Enforce minimum order amounts for specific payment types.

Troubleshooting Tips

If your script isn't working, check the console for errors. Ensure you're using the correct property names (e.g., Input.cart.total_price.cents). Also, verify that your script is deployed and not just saved. If you're using pre-built scripts, double-check the configuration.

Conclusion

Shopify Scripts are a powerful tool for checkout automation. By writing or using pre-built scripts, you can apply custom rules to hide or show payment methods based on location, cart items, and more. This not only streamlines the checkout process but also reduces fraud and improves customer experience. Start experimenting with scripts today to unlock the full potential of your Shopify Plus store.
