About
An application programming interface key (API key) is a code passed in by computer programs calling an application programming interface (API). It is used on the sites of the sales form. To access the API key, on some sites you can find it yourself (usually by clicking the button), and on some sites you have to contact the support to give you your API key. After using, your API key will change.

Usage
When there is a problem during the sale (the user can't buy a thing), at that moment you can give your API key and everything you set in the last 24 hours will be purchased from the user who submitted the API key.
