How the WPPF Update Helper Connects Private Plugins to Native WordPress Updates

Introduction In the previous article, I wrote about the WP Plugin Update Server , a plugin that allows a WordPress site to act as a self-hosted update server for privately distributed plugins. But the server is only one half of the system. A private plugin still needs a way to participate in WordPress’ native update workflow. It needs to: check whether a new version exists show update notices in the admin populate the “ View Details ” modal for plugins download protected packages when needed install correctly even when GitHub ZIP archives use inconsistent folder names That’s the role of the WPPF Update Helper . It is the client-side package that lives inside the plugin being distributed and connects that plugin to a configured update server. Why the Helper Exists The update server exposes metadata, but WordPress does not automatically know how to use that metadata for a privately hosted plugin. By default, WordPress expects plugin update information to come from the official WordPress.
