Question

quick question – Is it possible to register facebook achievements passing in a url that is only served by my local development server (i.e. localhost)? Or do I actually have to host the app on the internet?

Thanks!

Answer 1

No, the URLs need to be reachable by Facebook’s crawler – this requirement is covered in the achievements documentation:

Each achievement must possess a unique URL with the appropriate Open
Graph protocol tags. We will scrape the achievement’s unique
URL and use the information provided in the tags to generate stories
in news feed and on timeline. Clicking these stories will redirect to
the achievement’s unique URL.
