How to restrict affiliate discount codes to specific products using Shopify collections

Last updated: September 10, 2025

By default, affiliate discount codes created through Superfiliate apply to all products in your store. However, you can restrict these codes to only work on specific products by using Shopify collections.

Why use product restrictions?

Product restrictions are useful when you want to:

  • Exclude certain products like gift cards, sale items, or specific collections from affiliate discounts

  • Prevent discount codes from stacking with existing product markdowns

  • Limit promotions to specific product categories only

How to set up product restrictions

Step 1: Create a Shopify collection

In your Shopify admin, navigate to Products > Collections and click Create collection. Give your collection a title and choose either:

  • Manual - to manually add specific products

  • Automated - to set conditions for automatic product inclusion

Add only the products you want the affiliate discount codes to apply to, then save your collection.

Step 2: Get your collection ID

After creating the collection, you'll need to find the collection ID. This appears in your collection's URL in the Shopify admin. For example, if your URL is:

https://admin.shopify.com/store/yourstore/collections/346350125205

The collection ID would be: 346350125205

Step 3: Contact support to apply the restriction

Once you have your collection ID, contact the Superfiliate support team and provide:

  • Your Shopify collection ID

  • Which programs you want the restriction applied to (or specify "all programs")

The support team will update your discount codes on the backend to only apply to products in your specified collection.

Important notes

  • The collection should contain the products you want the discount to apply to, not the products you want to exclude

  • Changes may take a few minutes to take effect after implementation

  • If you create new affiliate programs in the future, make sure to request the same collection restriction for consistency

  • This restriction applies to discount functionality - it doesn't affect which products appear on affiliate landing pages
