Post a voice status

POSThttps://api.wapito.com/v1/stories/audio

Send a channel token on every request: Authorization: Bearer wpt_YOUR_TOKEN

Last reviewed September 17, 2026

Posts a voice status: an audio clip shown on a coloured background, which WhatsApp treats like a voice note in the status tray. Wapito converts your input to the Opus format WhatsApp requires. Voice statuses cut through better than text for short personal updates, and like every status they expire after twenty-four hours.
