Telegram bot in php. Problem with deleting messages. How right?

Question

Bots

Good day!!!

chat_id if you write to the bot in a personal message, the value is positive, if you write from the group, it is negative.

deletMessage ( 123123123, 123123 ) deletes messages fine, but not with a negative value.

How to solve this moment, tell me ...

ps . Some kind of nonsense ... Created a new group, chat_id is also a minus value - everything is perfectly deleted, but not in the desired group ...

Answer 1

It is necessary for the bot in the group settings to explicitly grant the rights to delete messages.

Answer 2

I asked myself, I answer myself ....
An error crept into the field of the table where I entered the chat_id value - the property was INT (11), valid values ​​​​are not enough to record chat_id, it was not the actual chat_id that was recorded, but the boundary permissible value ...
