Every published campaign in Galantis Discount Flow is a real Shopify discount. At checkout, the discount Function evaluates your campaign’s conditions against the live cart and applies the result — so the discount a customer sees is always computed from what’s actually in their cart at that moment.

​
Automatic vs code-based campaigns

A campaign becomes one of two kinds of Shopify discount, depending on how the flow is built:

Automatic

The default. The discount applies at checkout on its own whenever the cart meets the campaign’s conditions — the customer doesn’t enter anything.

Code-based

Created when the flow contains a Discount code condition. The customer enters the code at checkout, and the campaign’s remaining conditions are then evaluated as usual.
Automatic discounts are applied by Shopify at checkout, so it’s expected that a customer doesn’t see the discount in the cart drawer or cart page. It appears once they reach checkout.

​
Condition evaluation at checkout

When a customer reaches checkout, the discount Function checks the campaign’s conditions against the live cart — items, quantities, totals, and (where used) customer attributes. Conditions are re-evaluated as the cart changes, so a discount that applied a moment ago disappears if the cart stops qualifying.
Customer-based conditions — customer tags, segments, order count, and first order — require the customer to be logged in at checkout. A guest checkout can’t match these conditions, so campaigns that use them won’t apply for anonymous customers.

Combination and stacking rules

Whether campaigns stack with each other and with other Shopify discounts follows each campaign’s Combinations settings, using Shopify’s standard discount classes — order, product, and shipping. A campaign only combines with discounts in the classes you’ve allowed. When multiple product discounts compete on the same cart line, the best one for the customer wins — they don’t stack on a single line.
If a discount seems to be “missing” when several campaigns are active, check the Combinations settings on each campaign first, then check whether a stronger product discount won on that cart line.

​
Integration with Shopify’s Discounts page

Published campaigns appear on Shopify’s native Discounts page in your admin, alongside any discounts you’ve created directly in Shopify. Clicking a Galantis campaign there opens it in Galantis Discount Flow for editing — so your team can start from either place.
Shopify enforces a platform limit: a store can have at most 25 active automatic discounts, across all apps and native discounts combined. Code-based campaigns don’t count toward this limit. See Troubleshooting if you hit it.
