I'm writing a Telegram bot and I want it to send a sticker.
It is said here, that to send a sticker that already exists on Telegram servers we can simply pass file_id. The thing is, I have absolutely no idea how to obtain file_id of any sticker. E.g. how do I send any sticker from Greater Minds pack? I suppose, this pack is on Telegram servers since they include it in every app.
To discover a sticker's file_id
:
Send the sticker from Telegram App to your bot.
Use the bot's getUpdates
method to receive the sticker. You should see the sticker's file_id
in the message.
Your bot may use that file_id
to send the same sticker to another user. Be careful; in the message there is a thumb
field, which also has a file_id
. Do not use that one to send the sticker. It won't work.
Another possibility, of which you may be aware, is that you can always download the sticker image to a disk file, then use that file as the sticker
parameter for sendSticker
method, equivalent to uploading the file.
