How to add HotelBeds API

Hi,

I would like to know if I have to pay anything to make a simple integration between hotelBeds and your plugin. I don’t know where do I have to put the API and the secret, and I don’t know which is the vendor URL . I thought it was “https://api.test.hotelbeds.com/activity-api/3.0/activities”, am I wrong? I got this from hotelbeds api docs.

Thanks in advance for your time,
Kind greetings
