Existing Database

I have a MongoDB for some backend processing. Can I use my existing MongoDB, to store the website data ? Or should I create a new database via Wix to store website data?

At this point in time there is no support to use external databases as long as you can’t access them through an open API.

If I am able to access contents of my external database, does Wix provide server (maybe Express) capabilities to route to that URL ?
