Three ways a plugin is covered
The honest answer to "does it support my plugin?" is that there are three different levels of coverage, and most plugins land on the second one without you doing anything.
- A native integration. The plugin has a purpose-built manifest, so its own configuration and definitions are understood directly.
- Auto-discovery. No manifest exists, but the plugin's content lives in post types, taxonomies and post meta, which WPChangeSync picks up automatically.
- A custom data source. Nothing is picked up automatically, so you point WPChangeSync at the plugin's own options, tables, post types or taxonomies yourself, without writing code.
Knowing which level applies tells you what to expect, and it is usually the difference between a smooth first sync and a surprise.
