Help coding the yourpay api

Hi All
I hope someone will help me with how to programme the yourpay WepAPI.
Here is the docs https://yourpay.docs.apiary.io/#/reference/0/app-data/app-data/200?mc=reference%2F0%2Fapp-data%2Fapp-data%2F200
I really like to have this API in the app to pay for some goods for our customers. I am not a programmer so hope someone will help me showing the block or help me do it maybe on remote screen.
