How can I call an external API?

I’m looking at designing a football league website, and would like some users to have the ability to update match results and player stats and I’d like my site to show upcoming matches.

The Webflow CMS doesn’t seem to allow this, so I was wondering if I setup a database with API’s updating and retrieving the data can this be displayed on a Webflow website?

What would I need to do (the database and API’s will be hosted elsewhere obviously.

Thanks,
Nick
