Best way to load arbitrary (API) content?

[richardhj]

What's the best way, to read arbitrary content (in the form of collection/entries) in the template engine?

More concretely, I want to use {{ collection:events }}, where the events collection shall be pulled from a remote API (Notion, in that case).
I've read the docs about Repositories and Data Retrieval and Manipulation, but I need a little kickstart to get it working.

A custom route would be easy here, but I want to maintain CMS functionality.

Thanks!

I'd probably opt for building custom routes/controllers or building your own tag to get the API data and return it into your templates however you want.

Tags are awesome, thanks!
So I decided to go with Tags when I have content that repeats and with custom routes when the content is not repeated.
