[TW][Important] Pre-Order DTS Maximum Update for Local Mall Sellers

Dear Developer,

To improve buyers' shopping experience, we will adjust the maximum Pre-Order DTS (Days To Ship) value allowed for Local Mall Sellers. Please review the following changes and update your API integration logic before the effective date to avoid item creation or update failures.

Reference SEH articles:

• Article 1
• Article 2

Scope of Impact

• Seller Scope: TW Local Mall Sellers

Summary of Changes

Adjustment of the Pre-Order DTS maximum

• Before: Local Mall Sellers were allowed to set the Pre-Order DTS value within the range of 2-7 working days.
• After: The maximum will be updated to 2-5 working days. Any value greater than 5 will be rejected by the system.

Recommended: Developers can use v2.product.get_item_limit to dynamically retrieve the current Pre-Order DTS maximum (response field: dts_limit > days_to_ship_limit > max_limit).

Validation Logic

Starting from the effective date:

• If the request contains a days_to_ship value greater than 5 working days (for the Pre-Order DTS setting), the system will block the request and the item / model will NOT be created or updated.
• For existing items / models whose days_to_ship exceeds 5 working days, any modification request that does not also update days_to_ship to a compliant value will be blocked by the system.

Related APIs:

• v2.product.add_item
• v2.product.update_item
• v2.product.add_model
• v2.product.update_model
• v2.product.unlist_item
• v2.product.init_tier_variation
• v2.product.update_tier_variation

Note: The system will NOT automatically modify the days_to_ship value of items / models that were created before the effective date. Existing items / models will keep their current days_to_ship value until the seller edits them.

Effective date

開發者您好,

為提升買家購物體驗,我們將調整商城賣家較長備貨天數 Pre-Order Days To Ship (DTS) 的可設定上限。請於生效日前檢視並更新您的 API 串接邏輯,以避免商品新增或更新失敗。

關於詳細政策,請參考賣家幫助中心文章:

• TW Local 商城賣家

變更重點摘要

較長備貨天數上限調整

• 變更前: 商城賣家較長備貨天數的可設定範圍為 2~7 個工作日。
• 變更後: 上限將調整為 2~5 個工作日,系統將阻擋任何超過 5 天的設定值。

建議:

• 開發者可呼叫 v2.product.get_item_limit 動態取得目前 Pre-Order DTS 的可設定上限值(Response 欄位 dts_limit > days_to_ship_limit > max_limit)。

驗證邏輯

自生效日期起:

• 請求中若帶有較長備貨天數 days_to_ship 值超過 5 個工作日,系統將攔截該請求, item / model 將無法成功建立或更新。
• 針對 days_to_ship 超過 5 個工作日的既有 item / model 進行變更請求時,若該次請求中並未將 days_to_ship 欄位值更新至符合條件的設定,系統亦將攔截該請求。

相關 API:

• v2.product.add_item
• v2.product.update_item
• v2.product.add_model
• v2.product.update_model
• v2.product.unlist_item
• v2.product.init_tier_variation
• v2.product.update_tier_variation

注意:系統不會主動更改既有 item / model 的 DTS 設定值,已建立的 DTS 值將維持,直到賣家自行編輯為止。

生效日期
