Setting up a Telegram bot can be somewhat tricky, but it's not really that hard to do.
- Firstly, login to telegram and message @botfather with the /newbot command. Botfather will ask you a few questions, and then give you a token. Copy and save this somewhere
- Next, create a private 'group' chat. Add the bot you just created to that group
- Now, add 'get id bot' to the group, and ask @get_id_bot what is this chat id. You want the 'group chat id' that the bot responds with. For group chats, this will always be a negative number (ie: -48853)
Save that information in the form and you're good to go
