強化轉換

CM360 離線轉換 API 支援利用使用者 ID，提升網站代碼式轉換成效。

建議設定

• 接受 CM360 中的 Floodlight 設定《強化轉換服務條款》。
• 使用比對 ID 來檢測網站。
• 記錄網站上發生的 Floodlight 轉換。請務必記錄以下所有內容，因為這些是後續 API 呼叫中的必填欄位：
  • matchId
  • ordinal
  • timestampMicros
  • floodlightActivityId
  • floodlightConfigurationId
  • quantity
  • value
• 自線上代碼擷取到轉換的 90 分鐘後，呼叫 conversions.batchupdate 即可透過使用者 ID 強化這些轉換。
  • 使用者 ID 應採用格式化和雜湊處理，並加入轉換物件的 userIdentifiers 欄位。
  • 必須指定數量和值。 您可以視需要在相同 conversions.batchupdate 呼叫中調整轉換價值，或是提供原始數量和價值。
  • 每一批次的插入與更新可包含成功和失敗的組合。如果轉換處理延遲的時間比平常久 (最多 6 小時)，則應重試 NOT_FOUND 失敗。
  • 線上代碼擷取轉換後，必須在 24 小時內透過使用者 ID 強化轉換。

正規化和雜湊處理

為保護隱私，電子郵件地址、電話號碼、名字、姓氏和街道地址必須使用 SHA-256 演算法進行雜湊處理後，才能上傳。為了使雜湊處理結果標準化，在對其中一個值進行雜湊處理前，您必須先完成下列事項：

• 移除開頭或結尾的空白字元。
• 將文字轉換為小寫。
• 根據 E164 標準設定電話號碼格式。

• 移除 gmail.com 和 googlemail.com 電子郵件地址中網域名稱前的所有半形句號 (.)。

將使用者 ID 加入轉換

首先，請準備 Conversion 物件，以便照常上傳或編輯，然後附加使用者 ID，如下所示：

  "matchId": "my-match-id-846513278",
  "ordinal": "my-ordinal-12345678512",
  "quantity": 1,
  "value": 104.23,
  "timestampMicros": 1656950400000000,
  "floodlightConfigurationId": 99999,
  "floodlightActivityId": 8888,
  "userIdentifiers": [
    { "hashedEmail": "0c7e6a405862e402eb76a70f8a26fc732d07c32931e9fae9ab1582911d2e8a3b" },

常見錯誤

以下是使用使用者 ID 強化轉換時可能出現的錯誤：

欄位 hashed_X 不是有效的 SHA-256 雜湊

所有前置字串為雜湊的欄位，都只接受以十六進位編碼的 SHA-256 雜湊。

欄位的國家/地區代碼長度有誤

country_code 必須剛好為 2 個字母。

Floodlight 設定尚未簽署強化轉換服務條款

要求的 Floodlight 設定 ID 尚未接受《強化轉換服務條款》。

已指定超過五個 user_identifier

一次轉換最多只能有 5 個使用者 ID。

常見問題

建議使用比對 ID 的原因為何？

以點擊 ID 為依據的編輯會排除點擊前未發生的轉換，並限制強化轉換整合的價值。

為何必須記錄數量和價值？

CM360 Offline Conversions API 必須指定數量和值。

我需要取得 Google 記錄的確切微秒時間戳記，才能編輯線上代碼式轉換嗎？

針對比對 ID 式編輯，API 現在接受編輯內容，前提是要求中提供的時間戳記必須在 Google 記錄時間戳記的 1 分鐘內。

為什麼在透過線上代碼擷取到轉換後，必須等待 90 分鐘才能進行改善？

線上轉換最多可能需要 90 分鐘才能由 API 建立索引，且可供編輯。

在 API 回應中，我該注意哪些事項？

即使 CM360 Conversion API 傳回成功回應，有些個別轉換仍可能無法上傳或更新。檢查個別 ConversionStatus 欄位是否失敗：

• NOT_FOUND失敗情形，應該重新嘗試，最多 6 小時，以免在轉換處理過程的延遲時間比平常長。另請參閱常見問題，瞭解 NOT_FOUND 錯誤為何會在 6 小時後持續存在。
• INVALID_ARGUMENT 和 PERMISSION_DENIED 錯誤不應重試。
