Telegram bot for sale of courses

The work was done on order. The project’s task is to create chat-bot telegrams for selling courses using the WayForPay payment system.

Functions of the BOT:
The user falls into the bot on one of the links (for the source tracking implemented a system of statistics of transitions to the bot on different links).
A simple registration procedure is carried out: name, age and phone. After filling in the form, the user chooses one of the courses. A confirmation of the application appears: the user can switch to the payment, or can refuse - then the administrators come a notification to their chat, after which they process customer objections.
After a successful payment, the user gets access to the course and the database is marked as the person who paid the product.

The admin part:
- The ability to view the total number of people who wrote a bot
- Sending function by categories (those who paid / didn't pay the course)
- Administrator can connect to any user in dialog mode (user messages come from the face of the bot)
