WhatsApp — Set group photo

Set/replace a WhatsApp group's photo (icon) by exact group name. Pass the image as base64 (imageBase64) — it is applied through the group-info photo editor, including the crop/adjust step. Verifies the group photo actually changed before reporting success, and returns the new photoUrl plus replacedExisting. Admin-only; notifies the group. Keep imageBase64 well under ~96KB (MCP payload cap); for larger images serve the file over localhost instead.

Input

group required

Exact group name, as shown in the chat list

imageBase64 required

The image bytes, base64-encoded (jpg/png/gif). Keep it well under ~96KB of base64 - the MCP transport caps the payload.

mime optional

Optional MIME type. Default inferred from filename (image/png, image/gif, else image/jpeg).

filename optional

Optional filename to present to WhatsApp. Default group.png

Output

set required
group required
photoUrl optional

The URL of the group photo after the change

replacedExisting optional

true if the group already had a photo that was replaced

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
