"""Use this method to delete messages, including service messages, with the following limitations:
|
||
|
|
|
||
|
|
- A message can only be deleted if it was sent less than 48 hours ago.
|
||
|
|
- Users can delete outgoing messages in groups and supergroups.
|
||
|
|
- Users granted *can_post_messages* permissions can delete outgoing messages in channels.
|
||
|
|
- If the user is an administrator of a group, it can delete any message there.
|
||
|
|
- If the user has *can_delete_messages* permission in a supergroup or a channel, it can delete any message there.
|
||
|
|
|
||
|
|
Args:
|
||
|
|
chat_id (``int`` | ``str``):
|
||
|
|

|
||
|
|
For your personal cloud (Saved Messages) you can simply use "me" or "self".
|
||
|
|
For a contact that exists in your Telegram address book you can use his phone number (str).
|
||
|
|
For a private channel/supergroup you can use its *t.me/joinchat/* link.
|
||
|
|
|
||
|
|
message_ids (``iterable``):
|
||
|
|
A list of Message identifiers to delete or a single message id.

||
|
|
Deletes messages on both parts.
|
||
