It is a bot for sending and fetching twitter DMs in realtime and can be integrated to any web-app or other services like any discord bot to send and recieve DMs directly from that web-app or service.
Provide all the keys to use the bot and also don't forget to give Read,write,direct message permission to your twitter app.
