Free Gifts & Rewards
Migrate to the unified discount function
Move from legacy per-reward functions to the unified discount function.
This article is a draft and may be incomplete or change before publishing.
What changed
Older versions of Oxify used separate Shopify Functions per reward type — one for free gifts, one for free shipping, one for cart-discount upsells, etc.
The current unified-discount-function runs all rewards in a single Shopify Function call. Faster, cleaner stacking, and avoids hitting Shopify's 5-function-per-cart limit.
How to migrate
Migration is one click:
- Open Settings → Discounts.
- Click Migrate to unified function.
- Confirm.
Existing tiers carry over automatically. No data loss, no downtime, no customer-facing change.
After migrating
Test in an incognito window: confirm rewards still apply at checkout exactly as before. If anything looks off, support can roll back.
