Available Licensing Models – Single Offer Extensions

Extensions with a single offer license can be installed on the server
but will not work without a purchased license.

License status	Extension behavior requirements
License installed	All extension’s functions are available
License not installed	Extension’s functions are unavailable; Controls and screens pertaining to extension’s functions are inaccessible; Attempts to access extension’s controls and screens pertaining to its functions result in displaying a “License required” message.

“License required” message example:

"The %%extension_name%% extension requires a license to function. You can purchase the license <a href="%%buy_url%%">here</a>."

Here, %%buy_url%% is the URL of the corresponding online store that
sells the said license. This URL must be obtained from the extension’s
metadata. Refer to the section Obtaining the Online Store URL
