For All markets：New Republish Activity API

The Promotion category adds a new Republish Activity API that lets sellers bring an expired or deactivated promotion activity (product discount or flash deal) back online for a new effective period. There is no need to recreate the activity or re-associate products and SKUs — promotions can be restored in a single call.

Value & Use Cases

• Lower cost, higher efficiency: Previously, restoring an expired activity meant recreating it and re-adding every product/SKU one by one — many calls, tedious work. The new API reuses the products and SKUs already tied to the original activity and only requires a new effective period, significantly cutting the number of add-products calls.
• Typical scenarios: Extending or reopening a promotion after it expires (e.g., mega-sale returns, flash-deal renewals); quickly recovering an activity that was deactivated by mistake; running periodic, rolling promotions on the same set of products.
• After republishing, the activity can be edited as usual — you can continue to add or remove products and SKUs.

• New endpoint:POST /promotion/202607/activities/{activity_id}/republish
• Supported activity types: Only FIXED_PRICE, FLASHSALE, and DIRECT_DISCOUNT activities.
• Applicable seller types: both local and cross-border.
• Preconditions: The target activity must have expired or been deactivated within the last 7 days; begin_time must be greater than the current time; otherwise error code 17003243 (This activity dont allow republishing) is returned.

• Before: Search Promotion Activities / Get Activity — locate the target activity_id and its status.
• After (optional): Update Promotion Activity / Update Promotion Activity Products / Remove Promotion Activity Products — adjust the activity and its products as needed once republished.
• Replaces: The old flow of recreate activity + Create Promotion Activity + re-add products one by one. TikTok Shop recommends using this API instead to reduce API requests.

• Effective version: 202607; launch: 2026-07.
• RC / preview version: None.

Integration: standard TTS signed authentication (app_key + sign + timestamp), pass x-tts-access-token in the header (seller access_token where user_type=0); cross-border shops must pass shop_cipher in the query. Request sample:

POST /promotion/202607/activities/{activity_id}/republish?app_key={app_key}&sign={sign}&timestamp={timestamp}&shop_cipher={shop_cipher}
Content-Type: application/json
x-tts-access-token: {access_token}

{
  "begin_time": 1784538000,
  "end_time": 1785142800
}

Success response sample (data.activity_id is the ID of the successfully republished activity):

{
  "code": 0,
  "data": {
    "activity_id": "7136104329798256386"
