# Show typing indicator

`POST /v1/messages/{messageId}/typing`

## Request

- Base URL: `https://api.zavu.dev`
- URL: `https://api.zavu.dev/v1/messages/{messageId}/typing`
- Auth: HTTP bearer

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.

## Path parameters

- `messageId` string, required

## Headers

- `Zavu-Sender` string

## Response `202`

Typing indicator displayed and message marked as read.

- object
  - `success` boolean, required

## Other responses

- `400`: Invalid request — message is not WhatsApp, not inbound, or has no provider message ID.
- `401`: Unauthorized.
- `404`: Message not found.
