# On WhatsApp message read

> Start an automation when a recipient reads a WhatsApp message.

`onWhatsAppMessageRead` starts an automation when WhatsApp reports a read receipt for a message.

```ts automations/track-whatsapp-reads.automation.ts theme={null}
import { automation } from "automate.ax"
import { onWhatsAppMessageRead } from "automate.ax/whatsapp"

export default automation("Track WhatsApp reads", () => {
  const event = onWhatsAppMessageRead()
  event.messageId
})
```

Optional static `account` defaults to the project's WhatsApp binding. The signal has `status: "read"` and includes the message and recipient IDs, timestamp, callback data, conversation, pricing, structured errors, and `providerEvent` described by [the broad status trigger](/reference/integrations/whatsapp/triggers/on-message-status-event).

Read receipts depend on the recipient's privacy settings and may not be emitted for every delivered message.
