How to process the acceptance of payment from the user through free-kassa?

Question

Payment systems

Hello, I want to set up payment for users through free-kassa, I have never done anything like this.
Prompt what algorithm of work, it is necessary to process mail? If yes, then it turns out that you need to write some kind of script or software that will check mail 24/7 or is there another solution?
In advance, thank you all for your help.

Answer 1

Look at their integration documentation :)
In your personal account, you specify the notification URL to which data with payment information will be sent.
When paying, the service will send a request to this address with the parameters specified in the "Payment Notification" subsection of this documentation.
You check everything in the script whether so: is there such an order, is it such an amount, and other parameters, if everything is ok, then you should display "YES"
An example of the script is on the same page in the subsection "Example of a payment processor
" CMS, see this section
