撤銷訊息
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
如果訊息已傳送但尚未送達,服務專員可以撤銷訊息。最好在未送達的訊息過期前撤銷。時間取決於代理程式的用途。舉例來說,您可能會在十分鐘後撤銷一次性密碼訊息,但會在特定到期日撤銷宣傳訊息。為確保訊息能及時送達,請務必及時撤銷訊息,以便透過簡訊等替代管道傳送訊息。
撤銷訊息的方法有兩種:
在極少數情況下,撤銷作業可能會失敗。舉例來說,代理程式可能會在 RBM 平台傳送訊息的過程中,嘗試撤銷該訊息。如果撤銷失敗,請檢查 Webhook 的 DELIVERED
事件。如果訊息尚未送達,您可以傳送新的撤銷要求,然後將訊息改用簡訊等其他管道傳送,確保及時送達。
範例
下列程式碼會傳送撤銷要求。如需格式和值資訊,請參閱phones.agentMessages.delete

It's\nbest to revoke undelivered messages before they go stale. The timing depends on\nyour agent's use case. For example, you might revoke an OTP message after ten\nminutes but revoke a promotional message on a specific expiration date. For\ntimely message delivery, be sure to revoke messages in time for you to send them\nby an alternate route like SMS.\n\nThere are two ways to revoke a message:\n\n- [Send a revocation request](/business-communications/rcs-business-messaging/guides/build/messages/revoke#example)\n to trigger the revocation. The 200 OK response confirms that the message was\n revoked and deleted from the user's queue. A 404 Not Found response means\n the revocation attempt has failed because the message was delivered.\n\n- [Set a message expiration](/business-communications/rcs-business-messaging/guides/build/messages/send#expire)\n to automatically revoke the message at the appropriate time. The RBM\n platform notifies your agent when the message has expired and confirms\n whether or not it was successfully revoked. See [Server-generated events](/business-communications/rcs-business-messaging/guides/build/events#server-generated_events)\n for more information.\n\nRevocation could fail on rare occasions. For example, your agent may attempt to\nrevoke a message while the RBM platform is in the process of delivering it. If\nrevocation fails, check for a [`DELIVERED` event](/business-communications/rcs-business-messaging/guides/build/events#delivered)\nat your webhook. If the message hasn't been delivered, you can send a new\n[revocation request](/business-communications/rcs-business-messaging/guides/build/messages/revoke#example)\nand then route the message to an alternate channel like SMS for timely delivery.\n\nExample\n-------\n\nThe following code sends a revocation request.
