Is there a way to access the Wix Database (data, members, password, etc.) from an external Application via an API?

Okay, thanks a lot for your response, i’ve made a get and a post request.

The problem now is that my collection is set as “Custom” to be accessed externally. And every body can literally post, put or delete data.

I can access the collection from my react native app, but everybody can, so the question is can we modify the function to have like a key or a specific access so that only the app can access for example ?
