LIVE sync settings let you control which metafields are written to your Shopify storefront. You can access them from the sync status popover on your Discount Kit dashboard.

​
LIVE sync (top-level toggle)

Enables or disables all sync activity. When turned off, LIVE stops all Shopify writes — including product metafields, collection metafields, discount summary metaobjects, and the shop-level metafield. Turning this off does not delete any metafields already written to Shopify — they simply stop being updated.

​
Product metafields

When enabled, LIVE writes discount data to individual product metafields under the app--9549316097--discount_kit namespace. This includes:
  • discounts — full JSON array of applicable discounts
  • max_reward_percent, max_reward_cents, max_reward_discount — scalar values for the best universal discount
Disable this if you only need collection-level data or want to reduce write volume.

​
Collection metafields

When enabled, LIVE writes discount data to collection metafields using the same namespace and keys as product metafields. Disable this if your theme only uses product-level data.

​
Collection fan-out

When enabled, LIVE resolves collection → product membership and writes product metafields for every product in a targeted collection. This means products inherit discounts from their parent collections automatically. For example, a “Summer Sale” discount on the “T-Shirts” collection will be written to every product in that collection — no extra Liquid logic required.
Collection fan-out is limited to 8,000 unique products across all collection-based discounts. Products beyond this limit still receive the correct discount at checkout but may not display badges on the storefront.

​
Important notes

  • Discount summaries sync with the top-level toggle — metaobject summaries and the shop-level metafield update whenever LIVE sync is on, regardless of the product/collection sub-toggle settings.
  • Toggling a setting ON triggers an immediate sync — changes are written within seconds.
  • Toggling everything OFF is safe — metafields already in Shopify remain intact but stop being updated. You can re-enable at any time to resume.
