"Sale" / access to content on the site through Donate (donations) - how to organize and what to use?

Question

Donations

How can I organize access to content on the site through Donate-donations (transfers, not payments for goods)?
There are all sorts of Donate-services for raising funds, such as "piggy banks" and others, with the help of which, in theory, anyone can collect money on their website.
So, if you do this: the visitor makes a donation and receives a gift from me - access to certain content and it all works without my confirmation / participation (i.e., automatically, like in payment systems).
Does something similar exist?
ps: technically, the most difficult thing is probably to find out what a particular user has donated, for example, his 500 rubles and what he (the user) should receive in exchange for his donation (access to which specific content)
ps: if that site already exists and it is on WordPress

Answer 1

Through Yandex money . You can attach a shopping list and whatever you want. Inserting is also easy - html code.
The form submission translates to php, which saves the record in the database and changes the user's rights in WP.

Answer 2

Yandex money has a notificationfire that notifies you of an incoming transfer and the amount credited.
To understand that it was this user who transferred this amount, you need to ask him to enter the transaction or wallet number on the site after the transfer.

Answer 3

The trick is that providing access for a donation is not a donation, but a sale. Especially if the amount is specified.
Donat is a gratuitous donation without the goal of getting anything in return.
You want to pay for content as a donation, which is not entirely correct legally. And if the relevant authorities (tax authorities, for example) have a desire to dig into you, then most likely they will start with this.
