Understanding How TrustZ Creates and Manages Free Shipping Discount Codes

TrustZ automatically creates and manages free shipping discounts for the Free Shipping Goal feature using Shopify's official Discount API. Each discount generated by TrustZ follows the format TZ_xxxxxx, and the app handles the creation, update, and expiration of discounts automatically, ensuring that your free shipping campaigns remain synchronized with Shopify.

How TrustZ Creates Free Shipping Discount Codes​

When a Free Shipping Goal is enabled, TrustZ generates a corresponding free shipping discount in Shopify. This process includes:

  1. Automatic Discount Generation: Whenever a merchant creates, updates, or deletes a Free Shipping Goal, TrustZ automatically generates a new discount. The previous discount will be set to inactive or expired to prevent conflicts with the updated configuration.

  2. Shopify Official Discount API: TrustZ relies on Shopify's official Discount API to create and manage discounts, ensuring seamless integration with Shopify's checkout and discount systems.

Non-Editable Fields​

To ensure the Free Shipping Goal functions correctly, certain key fields should not be modified:

  1. Customer spends: This determines the minimum cart value required to qualify for free shipping.
  2. Customer gets: This defines the reward customers receive when they reach the configured goal, which is free shipping.

Modifying these values directly in Shopify may cause the Free Shipping Goal to function incorrectly.

Editable Fields and Considerations​

While some discount settings can be edited, there are important considerations to keep in mind:

  • Active Date: You may adjust the start date of a TrustZ-generated discount. However, if you modify the activation period, ensure that the corresponding end date is configured correctly to avoid overlapping discounts.

  • Updates to Shopify: Since TrustZ generates a new discount whenever a Free Shipping Goal is updated, merchants should ensure that the latest TrustZ-generated discount remains active and that outdated discounts are not used in other promotional campaigns.

Shopify Automatic Discount Limits​

TrustZ-generated discounts are subject to Shopify's discount limitations.

Shopify allows a maximum of 25 active automatic discounts per store, including discounts created by third-party apps such as TrustZ. This means that TrustZ-generated discounts count toward Shopify's automatic discount limit.

If your store has already reached this limit, Shopify may prevent additional automatic discounts from being created until some existing discounts are disabled or removed.

Shopify Discount Combinations​

TrustZ discounts also follow Shopify's discount combination rules.

Depending on your Shopify settings, free shipping discounts may be combined with other eligible product or order discounts. The ability to combine discounts is controlled entirely by Shopify's discount engine and configuration.

By following these guidelines, you can efficiently manage your Free Shipping Goal campaigns using TrustZ's automated discount creation system while ensuring your store remains optimized and compliant with Shopify's discount framework.
