# Query the read status of an enterprise bot's group chat message

> Call this API to query the send status of an enterprise bot's group chat message and the userIds of members who have read it.

Call this API to retrieve information such as the message delivery status and the userIds of users who have read the message. For example, after an enterprise bot sends a group chat message in an internal group chat, you can use this API to query the userIds of users who have read the message.
