How to get bot message ID in python TelegramBotApi or aiogram?

Question

Bots

I need the bot to determine the ID of its last message so that it can be deleted later.

Answer 1

The only option that comes to mind is the user's last message + 1.
That is:

@dp.message_handler()
async def other_command(message: types.Message):
    next_id = message.message_id + 1

next_id - id of any next message, no matter from whom.

Answer 2

For a bot that will be used by more than 1 person, it is better not to resort to the method:

@dp.message_handler()
async def other_command(message: types.Message):
    next_id = message.message_id + 1

In this case, we write down the id of the message, which does not yet exist, if another user sends a message before the bot, then message.message_id + 1 will be assigned to the message of another user.
The bot will not be able to delete the message with next_id = message.message_id + 1, and the error "Message can't be edited" will occur.
For a multi-user bot, in order to avoid such a situation, it would be better to write:

@dp.message_handler()
async def bot_answer(message: types.Message):
    msg = await message.answer('Последнее сообщение бота')
    next_id = msg.message_id
