I'm developing an iOS app(coded in Objective-c) which plays Vimeo videos. Its an In App Purchase application. I already have websites where users can buy videos. I have Vimeo PRO account. I don't know how to get direct link to those videos using Vimeo API.
Is requesting for videos part mine or it is done in back-end(in my case PHP)? So how to make API request to those videos I own in order to show them in my app? Thanks
