Integrate Duffel.com's API with Bubble.io Application

So, very easily, I need you to integrate my bubble.io app with Duffle.com API. duffle is a service that allows websites to integrate into their platform so they can search for flights and sell them.

I need a very fast service that consists in:
- Setting up the proper GET and POST protocols on my bubble.io app from Duffel.com
- No need to do web design
- Backend API
- And constant communication with me.

Thank you!
