Summary

What are the key benefits and features of syncing Shopify promotions with TikTok Shop?

Syncing Shopify promotions (except Free Shipping) to TikTok Shop saves time by eliminating manual recreation, ensures consistent marketing across platforms, and streamlines promotion management for better customer engagement.
The new Buy X Get Y (BXGY) model offers flexible discount configurations, including percentage or fixed discounts on Y items, same product X and Y, and per-order usage limits, improving sync coverage and promotional flexibility.

How does the promotion sync policy affect editing and managing promotions between Shopify and TikTok Shop?

Shopify-synced promotions cannot be edited directly in TikTok Shop Seller Center; all changes must be made in Shopify and then re-synced to TikTok Shop to maintain data integrity.
Promotions synced from Shopify are tagged in TikTok Shop for easy identification, and sellers can close syncing but cannot edit synced promotions on TikTok.

What are the common risks or conflicts sellers might encounter when syncing promotions, and how can they resolve them?

Promotions flagged as "Promotion discount risk" occur due to conflicting rules, stacking issues, or quantity threshold differences (e.g., Y quantity in BXGY promotions), requiring manual confirmation or adjustment in Shopify before syncing.
Sellers can manually sync, fix the promotion in Shopify, or ignore the promotion (which moves it to Not Sync status) and re-sync later if needed.

What are the main rules and behaviors regarding stacking and priority when multiple promotions apply to the same product?

Only one discount applies per product when multiple Buy More Save More promotions overlap; priority is determined by event type, minimum purchase requirements, discount strength, and creation time.
The priority order favors full amount discounts over reductions, lower minimum purchase requirements, higher discounts, and older events when tie-breaking.

How can sellers set up, re-sync, or unsync promotions between Shopify and TikTok Shop?

To set up, create the discount in Shopify, select TikTok as a sales channel, then verify and sync promotions via the TikTok app in Shopify under Shop Management > Marketing > Promotion Sync.
To re-sync, sellers manually trigger sync in the TikTok app; to unsync, they can deselect TikTok as a sales channel in the discount settings or use bulk actions to unpublish promotions from TikTok Shop.

Overview:

Shopify sellers can sync Promotions/Discounts except Free Shipping on Shopify directly to TikTok Shop (TTS) with a one-click sync feature. This capability ensures sellers can efficiently manage their promotions across all platforms without manual duplication.

With the latest updates, TikTok Shop now supports an enhanced Buy X Get Y (BXGY) promotion model, allowing more flexible promotion configurations and improved synchronization behavior between Shopify and TikTok Shop.

Key Benefits:

✅ Improved Efficiency – Saves time by eliminating the need to recreate promotions manually.

✅ Increased Marketing Penetration – Ensures consistent promotions across platforms, helping maximize reach and conversion.

✅ Streamlined Promotion Management – Empowers Shopify sellers to streamline their promotions, maintain consistency, and drive better engagement with customers.

Understanding Your Discount Sync Policy:

Shopify-synced promotions are now clearly identifiable via dedicated tags in TikTok Shop Seller Center.

To maintain data integrity:

Shopify-synced promotions cannot be edited directly in TikTok Shop Seller Center
All modifications must be made in Shopify, and then re-synced to TikTok Shop.

Buy X Get Y (BXGY) Promotion Model

The new BXGY promotion model introduces several enhancements compared to the previous Gift With Purchase logic.

Flexible Y Discount Configuration

The new model supports more flexible promotion structures.

Examples include:

Y can be a discounted item, not only a free gift
X and Y can be the same product
Y can use percentage discounts or fixed amount discounts

Per Order Usage Limits

Sellers can define how many times the BXGY promotion can be applied in a single order, helping prevent overuse.

Improved Promotion Sync Coverage

Many Shopify BXGY promotions that previously could not sync can now sync automatically to TikTok Shop.

Promotion discount risk

Some promotions may be flagged as Promotion discount risk if differences exist between Shopify and TikTok Shop promotion rules.

BXGY Stacking and Conflict Rules

When BXGY Can Sync Automatically

BXGY promotions can automatically sync when:

They are configured to stack with product discounts and order discounts
There are no conflicting promotion rules

When BXGY Requires Manual Sync

BXGY promotions may require manual confirmation if:

The promotion does not allow stacking with product or order discounts
There are existing promotions active that could conflict

In these cases, the promotion will be marked as Promotion discount risk and sellers will need to manually confirm the sync.

Quantity Difference Risk

If the Get (Y) quantity is greater than 1 and the item is not free, the promotion will be marked as mePromotion discount riskThis is because:

Shopify supports Y quantity thresholds
TikTok Shop currently does not enforce Y quantity thresholds

Example: If a promotion is configured as Buy 2 items (X) and get 50% off 3 items (Y) in Shopify, the discount will only apply when exactly 3 Y items are purchased, and not when fewer than 3 Y items are bought.

However, in TikTok Shop, the promotion does not enforce this Y quantity threshold. Instead, it follows an “up to” logic, meaning the discount can apply to up to 3 Y items. For example, the discount will still apply even if the buyer purchases only 1 Y item.

As a result:

The promotion may apply discounts earlier than intended
The discount cost per order could increase

Sellers will need to review and confirm the sync before the promotion is activated.

Risk Promotion Handling

Promotions detected as Medium or High Risk will appear in the Need Action section of the Promotion Sync page.

Sellers can take the following actions:

Manual Sync – confirm the promotion and proceed with synchronization
Fix – update the promotion configuration in Shopify
Ignore – choose not to sync the promotion

If a promotion is ignored:

It will move to Not Sync status
It can be re-synced later at any time.
