WhatsApp — Create group
Input
name requiredGroup subject (title)
members requiredContact names to add. Each name must match the contact's display name exactly.
seedMessage optionalOptional: send this text into the new group immediately after creation. WhatsApp does not index a brand-new, message-less group in its own search box until it has at least one real message, so a group created without this can be briefly unfindable by name for follow-up scripts (e.g. delete_chat, leave_group, send_message). Pass a short text here to make the group immediately searchable. Off by default — omit to skip (no extra message sent).
Output
group requiredcreated requiredmembers requiredseedMessageSent optionalPresent only if seedMessage was provided; whether it was sent without WhatsApp flagging a send failure.
WhatsApp — Get conversation
Open a WhatsApp chat by its exact name (as returned by get_inbox) and return its messages in chronological order: sender, direction (sent/received), time, date, text and media type. `count` = how many recent messages to load (scrolls up for older). A message that was deleted for everyone is still returned, flagged with `deleted: true` and carrying no text, so it is never mistaken for a message that could not be read.
WhatsApp — Send message or attachment
Send a WhatsApp message to a chat picked either by its exact name (as returned by get_inbox) or by phone number in international format, which needs no saved contact. The message is either text, an attached image, video or document with an optional caption, or a saved contact's card. Confirms the send by inspecting the conversation afterwards — a delivery tick for text, a cleared upload for an attachment, the contact's own bubble for a card — and throws if WhatsApp flagged it as failed or left it stuck, rather than trusting the bubble appearing. Returns the message id, the account that sent it, and whether identical text was already in the conversation beforehand. Attachment bytes must be supplied inline, since they cannot be fetched from a URL at run time.
WhatsApp — Get inbox
List the WhatsApp chat list (inbox): for each chat its name, date/time label, read/unread status, unread message count and last-message snippet. Ordered top→down (most recent first). `count` caps how many chats to return.
