How to Get Page 2 / Paginated RSS Feed with Custom Permalink Structure?

As an update. It turns out that what I’m trying to do is outside of RSS’s specification. So the short answer is “don’t do that, use an API”.

But had I wanted to hack around that spec, I could

  • Use the Custom Permalinks plugin
  • Go back to the default permalink mode in the site’s settings
  • Then the paged parameter would work for a custom RSS feed in my theme.

Overall I’m going with the API, and will just make sure it’s secure.
