# Show typing indicator

> Mark an inbound WhatsApp message as read and display a typing indicator to the user while you prepare a response. The indicator is automatically dismissed when you send a reply, or after 25 seconds — whichever comes first. Only valid for inbound WhatsApp messages. Use this when a reply will take more than a couple of seconds (LLM agent, tool call, lookup) to improve the recipient's experience.
