I am new in envato. I am planning to sell PHP apps in Codecanyon. I was wondering if there was any way to validate the purchase of my app.
I will make an installer for my app. When the buyer will try to install the app in his/her server, in the installation page, the installer will ask for a purchase code (or something unique that is given by Codecanyon when the buyer bought the item). The installer will check the purchase code through an API and tell whether the purchase is valid or not. If the purchase code is invalid, the installation process is stopped, otherwise, the installation will continue.
Is it possible? or is there any other solution by which I can check my app is only used by a valid person?
I think it is really necessary to stop the unwanted distribution of any app/script.
I found an article where Envato says,
None of the items in our curated library requires a purchase code. You will have complete access to utilise the items core features as intended.
Does that mean I can’t do anything such?
