收發訊息收據

簡訊回條通知寄件者已收到訊息。讀取。使用者可以透過收據查看服務專員是否已讀取訊息，表示自己想要得到回覆你的代理程式也能判斷使用者收到對話的時間點和讀取訊息，方便你追蹤收據指標，提升互動體驗設計。

服務專員會透過 Webhook 接收收據。以相同方式接收及處理收據您接收的方式訊息。

使用者一次傳送或讀取多則回條訊息時，單一酬載會包含所有訊息回條。請檢查每則收據，確認郵件是否與郵件相關聯。

收據類型

Business Messages 支援送達回條和讀取回條。

使用者的收據

服務專員可接收使用者傳送的下列收據：

送達回條 (DELIVERED) 表示使用者已收到訊息數據資料
讀取回條 (READ) 表示使用者已讀取服務專員的訊息。

使用者可以選擇不傳送讀取回條。即使孩子拒絕啟用，仍可收到代理程式要求讀取回條

服務專員的收據

使用者可以接收服務專員的讀取回條。

讀取回條 (READ) 表示服務專員已讀取使用者傳送的訊息。如果對話是由多個真人服務專員負責管理，則會顯示讀取回條代表至少有一位服務專員已讀取使用者的訊息。

格式

使用者的收據

使用者的送達回條格式如下：

{
  "agent": "brands/BRAND_ID/agents/AGENT_ID",
  "conversationId": "CONVERSATION_ID",
  "customAgentId": "CUSTOM_AGENT_ID",
  "sendTime": "SEND_TIME",
  "receipts" : {
    "receipts": [
      {
        "message": "conversations/CONVERSATION_ID/messages/MESSAGE_ID",
        "receiptType": "DELIVERED",
      }
    ],
    "createTime": "RECEIPTS_CREATION_TIME",
  },
}

使用者的讀取回條格式如下：

{
  "agent": "brands/BRAND_ID/agents/AGENT_ID",
  "conversationId": "CONVERSATION_ID",
  "customAgentId": "CUSTOM_AGENT_ID",
  "sendTime": "SEND_TIME",
  "receipts" : {
    "receipts": [
      {
        "message": "conversations/CONVERSATION_ID/messages/MESSAGE_ID",
        "receiptType": "READ",
      }
    ],
    "createTime": "RECEIPTS_CREATION_TIME",
  },
}
