How to implement a paid subscription?

Question

Payment systems

It is necessary to sell the service of access to the admin panel of this site on the site.
Tell us how to make it so that people can pay for access to their account to the admin panel, and so that when they pay they have access, and if they don’t pay, we still wait a month, and then access is turned off?
Of course, do not manually check the payment and on / off in the settings.

Answer 1

robocaassy, ​​merchandisers,
any job at your robokassa, any ddos ​​and hundreds of people will not have paid access.
The person has a login:pass from the admin. All payments must be made by the 20th of this month.
He is trying to log in:
today is the 5th - we let him into the admin panel
today on the 25th - we say that he has time to pay for the admin panel before the 20th of the next month and we let him into the admin panel
today on the 21st of the next month - we don’t let him in.
only three checks, you just need to fasten the payment and immediately after the payment update the time in the database, until which everything is paid.
Personally, I strive to reduce dependencies on third-party services, which I advise you, it can save your customers and customers at the most important moment.

Answer 2

merchant + recurring payments
are not available everywhere, and not in all payment systems

Answer 3

Answer 4

For almost all payment gateways, you can specify the URL of your handler on the site in the settings.
At least 2 parameters will be sent to this URL: the amount of payment and the id of the account/Account of the buyer (This Id is passed to the payment gateway at the time of payment).
