@ismaelc Our authentication process is fairly simple in the fact when you sign up for an account you are given a auth_key and auth_secret which then gives you access to make a call request. Very similar to other API's. Our API was built by developers for developers to be very easy to implement and use for a wide range of products.
Added this to Mashape (left the OAuth part as manual entry). Would you like me to transfer it to you so you can make changes to it in the future? https://www.mashape.com/community/given-to
