From the Tokens blog:
Today, we’re proud to launch Tokens 1.5. This update brings support for Apple TV apps and marks an interesting point in the development of the app.
iTunes Connect (iTC) has changed a lot in the years since we first launched Tokens. The first version interacted with iTC entirely by scraping HTML. This technique was inherently slow and fragile. A chain of page requests were required for every query and minor text changes on iTC could break our scraping code. Over the last two years, iTC has improved dramatically in this respect; it is now almost entirely a modern front end web application backed by a JSON API.
If you're a Mac or iOS developer, Tokens is a must-have. With the latest iTunes Connect changes, the app can even work for users limited to Marketing roles. Tokens is only $29 – a steal considering the time it'll save you for generating and saving promo codes.
