Telegram bot with payment and automatic access issuance (sales)

Telegram bot that fully automates the sales of digital products.

The user goes through the process:
— enters the bot
— sees the offer
— makes a payment
— automatically receives access

Without administrator involvement.

What has been implemented:
— Payment acceptance (Stripe / WayForPay)
— Payment verification in the system
— Automatic access granting (link / channel / course)
— "Check payment" button for the user
— Error handling (if the payment did not go through)

For the business owner:
— Storing users in a database
— Visibility of who entered and who paid
— Ability to upsell (contact those who did not buy)
— Control of all payments

How it works:
After payment, the bot checks the payment status and grants access.
If the user did not pay — the system reminds and returns them to the purchase.

Result:
The business receives an automatic sales system,
which operates 24/7 without managers and does not lose customers.

Suitable for:
— online courses
— information products
— closed channels
— subscriptions
— training

I can adapt it for any product and connect the necessary payment system.
