Connect Wix to our API

I'm building a new business called www.Ferret.live. We have a cloud SQL database with a simple URL based API with First Name, Last Name and Birthday entered and it returns a JSON format showing up to 6 text fields. I need some code added to Wix to connect to this API like this: https://banna.app/api/getCases.php?fn=tyler&ln=hart&bd=1994-01-01
