Build a Website - JSON API Integration 3 Different APIs

I have a website which is wordpress based, I need to integrate these 3 APIs and need to know if this can even be done. I need only the back office when a client logs in showing this. Here are the three APIs if you have valid experience and know you can do this and provide any examples I am looking at starting right now. Basically these should all become visible when the client is logged into the "My Account Section" of the theme, do not need is displaying in the WordPress Dashboard. Please do not message me if you have never dealt with JSON format, please do not message me if you cannot speak English and if you only make excuses. Include the word dog in your initial correspondence. Here are the 3 APIs: [login to view URL] [login to view URL] [login to view URL]
