What is the name of the method that returns a bot with a parameter to telegram?

Question

Bots

I want to connect the acceptance of payments using Qiwi, they have a function for accepting payments.

But I don’t understand how the teleram bot calls the method that would process the response of the payment system, let’s say we give the user a payment link in the bot, after successful payment we want to send the user back to the bot and pass the parameter that the payment was successful.

What is the name of this method in which you can return the user back to the telegram bot and also send the parameter whether the payment was successful or not
