Edit (or cancel) an event

Edits an event THIS instance created, identified by `eventMessageId`. Resend the full set of event fields — every field is replaced with the new values, matching WhatsApp's edit semantics. Set `canceled` to `true` to mark the event as cancelled. Only the original creator can edit, so the event must have been sent from this same device/instance (its message secret is required).

Send a document message POST

Sends a document (PDF, spreadsheet, archive, etc.) to a WUTS-connected WhatsApp recipient. The document may be supplied as a base64 string or downloaded from a URL, with optional MIME type, file name, caption, thumbnail, mentions, and quoted reply.

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`.
