# Send message in conversation

The **Send Message in Conversation** action is used to send a message within 24 Hrs conversation window on WhatsApp. Unlike the **Send Message** action (which even works when 24 hrs conversation window is closed), this action is designed only where conversation window is open.
The main use-case of this action is to send Follow-up messages.
