发送和接收消息回执

消息回执会告知发件人他们已收到或阅读。借助回执，用户可以看到代理已经阅读完消息的时间，他们知道等待回复您的代理还可以决定用户何时收到和阅读消息，以便跟踪收据指标，从而更好地进行互动设计。

代理在 webhook 中收到收据。以相同的方式接收和处理收据接收的方式消息。

如果用户接收或阅读多个收据，则单个载荷包含所有消息回执。检查每个相关邮件的回执。

收据类型

Business Messages 支持送达回执和已读回执。

用户收到的收据

代理可以从用户那里收到以下收据：

送达回执 (DELIVERED) 表示用户收到了消息联系。
已读回执 (READ) 表示用户阅读了代理发来的消息。

用户可以选择不发送已读回执。如果他们选择不接收，仍会收到已读回执。

客服人员发来的收据

用户可以接收来自代理的已读回执。

已读回执 (READ) 表示代理阅读了用户的消息。如果有多位人工客服正在管理对话，系统会显示已读回执表示至少有一个代理阅读了用户的消息。

格式

用户收到的收据

用户发送的送达回执采用以下格式：

{
  "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",
  },
}

用户已读回执采用以下格式：

{
  "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",
  },
}

客服人员发来的收据

以下代码会从代理发送已读回执：
