Creating an extension
This guide is incomplete. Please help us complete it using the "Edit this page" button in the sidebar. Thanks! If you're looking to create your own extension, this documentation will tell you the bare minimum required, but looking at existing extensions will probably be necessary to get a complete idea on how to write one.
So you've decided to create an extension. Let's get started with the basics. In this guide, we'll inspect the example extension and create our own one based on that.
How do extensions work?
Creating a module
FOSSBilling modules all reside under the /modules directory. Their directory must be named as follows: 'Example'. Any other variation of capitalization will not work (Examples of invalid directory names: 'eXample', 'example').
All modules are required to have at a minimum a manifest.json file and a Service.php file.
For more information, please see the file structure (opens in a new tab) documentation and the Example module (opens in a new tab) GitHub repository.
Creating a payment adapter
All payment adapters should reside under the /library/Payment/Adapter folder. They should all extend the Payment_AdapterAbstract class and implement it's functions.
The Payment_AdapterAbstract class has inline documentation of each function to aid in the development of payment adapters. You can find the most up-to-date version of this here (opens in a new tab)
Creating a domain registrar
All domain registrars should reside under the /library/Registrar/Adapter folder. They should all extend the Registrar_AdapterAbstract class and implement it's functions.
The Registrar_AdapterAbstract class has inline documentation of each function to aid in the development of domain registrars. You can find the most up-to-date version of this here (opens in a new tab)
Creating a server manager
All server managers should reside under the /library/Server/Manager folder. They should all extend the Server_Manager class and implement it's functions.
The Server_Manager class has inline documentation of each function to aid in the development of server managers. You can find the most up-to-date version of this here (opens in a new tab)
