What are the ways to implement for the notification of sales on the site?

Question

CRM

I welcome everyone! Tell me what are the ways to implement a sales notification on the site according to the following scheme:
The buyer pays for a digital product on the site -> the operator receives a notification with the name of the product. This application must be taken into work by one of the service operators and then executed. Ideas with the simplest telegram bot come to mind. There is also an idea with CRM integration and here two birds with one stone will be killed at once in the form of obtaining sales statistics. What other ways are there?

Answer 1

There are millions of ways to integrate software subsystems.
