Telegram — List a group's members
Input
peerId requiredThe group's peer id, as returned by get_inbox (groups and channels are negative, e.g. "-5521853307"). A broadcast channel you do not administer has no member list and is refused.
Output
peerId requiredThe peer id that was actually opened, read back from the address bar.
members requiredThe member rows read from the panel, in the order the panel lists them.
complete requiredTrue when membersRead matches the total Telegram reports, so nothing was left unloaded. False means the list is partial — large groups load lazily and this reports the shortfall rather than passing off a truncated list as the whole membership.
membersRead requiredHow many member rows were actually read. Equal to members.length; kept as its own field so a short read is obvious next to membersCount.
verified_on_page requiredTrue when the members were read from a rendered member list, rather than an empty panel being reported as an empty group.
chatTitle optionalThe group's title — echo this to a human, since a peer id is not recognisable.
membersCount optionalThe member total Telegram reports on the group's profile, parsed from the digits in its own subtitle. Null when no number was shown. Compare with membersRead to see whether the list was fully loaded.
Telegram — Download a message's media
Pull the bytes of a document, photo or video attached to a Telegram message, given its conversation peer id and message id, returned as base64 plus the filename Telegram stores it under. Drives the message's own Download action and reads the file out of the app rather than relying on a browser download, and refuses a message that carries no media. Two side effects worth knowing: opening the conversation marks it read, and Telegram also saves the file to the browser's download folder. Note that photos are Telegram's re-encoded JPEG, not the original upload; documents come back byte-for-byte.
Telegram — React to a message
Add your reaction to a Telegram message, or take it back with remove:true, given the conversation's peer id, the message id and the emoji. Scope: the emoji must already be one of the reactions on that message — Telegram's reaction picker renders each choice as an animated canvas with no machine-readable identity, so a brand-new reaction type cannot be selected reliably, and this reports which emojis are available rather than clicking a guess. Resolves the emoji through Telegram's own reactions table instead of any translated label, confirms the change by the reaction pill's chosen state, and refuses Saved Messages, where the same-looking picker applies tags rather than reactions.
Telegram — Send a message or a document
Send a text message, a document, or a document with a caption to a Telegram conversation identified by its peer id (the id get_inbox returns), optionally as a reply. Confirms the send by finding the outgoing bubble in the conversation afterwards rather than trusting the click, reading back the document's filename and size and requiring the quoted-message embed when a reply was asked for, and reports whether the same message or file was already there plus which account sent it. Refuses conversations with no composer, such as broadcast channels you do not administer.
