Respond (RSVP) to an event

Sends an RSVP to an event the device has received, identified by `eventMessageId`. `eventResponse` is one of `GOING`, `NOT_GOING`, or `MAYBE`. For events in a group, pass `participant` — the JID/number of the event creator — so the original event can be located; in 1:1 chats it defaults to the chat. You cannot RSVP to an event you created yourself.

Send an event POST

Sends a WhatsApp event card to a group or 1:1 chat. An event carries a name, an optional description, a start time (and optional end time), an optional location and call/meeting link, and flags such as `extraGuestsAllowed` and `canceled`. Times accept RFC 3339 (`2026-07-01T18:30:00-03:00`), a local datetime plus `timeZone`, or a Unix epoch. WUTS attaches a per-message secret so recipients can RSVP later via `/send/event-response`.

Send an image message POST

Sends an image to a WUTS-connected WhatsApp recipient. The image may be supplied inline as a base64 string or fetched from a URL, and supports captions with WhatsApp markdown, mentions, quoted replies, and view-once delivery.
