I want to know an example of removing message or file like a photo
I did not find any functional tutorial in this regard,
There is an official support of deleteMessage method in Bot API 3.0. More details here: https://core.telegram.org/bots/api#deletemessage
https://api.telegram.org/botTOKEN/deleteMessage?chat_id=CID&message_id=MID
As you can see there are two arguments: chat_id
and message_id
.
You can remove bot's messages or other messages (if bot is admin) except service messages (such as join/leave messages).
On success, it will return following JSON object:
{"ok":true,"result":true}
.
If you are trying to remove service message or other user's message, but bot is not an admin:
{"ok":false,"error_code":400,"description":"Bad Request: message can't be deleted"}
.
If you are trying to remove non-existent message or its already deleted:
{"ok":false,"error_code":400,"description":"Bad Request: message to delete not found"}
