add api to cake php page like this

Hello, Here is a screen shot of the job [login to view URL] There are 2 parts that need coding, 1. You will add the reservation code to the top left box- I will give this to you. 2. You will grab the info with the API, so we can display hotels etc. The rest of page is explained in the image. You will need to tell me first what info is obtained from API, so I can give to graphic artist.
