Connecting Wix form to CRM Database

Hi! I’m planning to create my recruitment agency website with Wix, I’m using Bullhorn as a CRM for the candidate database.

My question is; Is it possible to connect a form on the wix website (e.g. to upload application documents and to register) with the CRM bullhorn, so the data and documents gets directly transferred into the CRM?

If yes, is there a good and detailed tutorial? I have created several sites with Wix but never worked with API.
