We provide a fully RESTful API and PHP SDK Client to integrate the platform with your website or existing applications. Our API supports almost everything and a lot more than what can be done via the GUI. This is an ongoing project and several updates are being made to the upstream regularly.
You can download or reference to the API repository here : https://github.com/mailfed/API
Refer the “examples” directory for documentation and “how tos” about integrating the platform with your applications.
