# Recall bot messages in one-to-one chats in batches

> Call this API to batch recall bot messages in one-to-one chats by conversation ID, robot code, and message ID list, useful for retracting mistakenly sent enterprise messages.

Call this API to recall bot messages in one-to-one chats in batches based on the chat ID, bot code, and message ID list. This API is suitable for scenarios where messages sent to your organization need to be recalled due to errors.
