We advise against using the API unless you fully understand what the code does and implies and if you’re willing to check up on changes every major release. Use the options instead, or submit a feature request if you can’t find what you need.
The SEO Framework
The SEO Framework (TSF) is extensible, interpretable, and adjustable.
The main facade object, obtained via
the_seo_framework(), can be accessed on or after actions
the_seo_framework_loaded. They run on action
plugins_loaded, at priority
5. You should never call the object before those actions.
You can find examples on how to utilize this at our filter reference.
The Extension Manager
The Extension Manager is the epitome of extending TSF. It is why we must keep TSF’s API vast, open, and reliable.
In the Extension Manager, the filters are used for debugging, and the actions are implemented for internal purposes only.
Some extensions in the Extension Manager have specific API functionality.
