23.7. Distributing Passes Using Web Services
Problem
You want users to be able to download your digitally signed passes right from your website.
Solution
In your web pages, create hyperlinks to your .pkpass passes. When users view the web pages on their devices, they can simply tap on those links. Once they tap on the link, Safari will detect that the link leads to a .pkpass file and will hand the link to Passbook, which will display the pass on the website and allow the users to add your passes to their Passbooks.
Discussion
Safari on iOS does not handle direct downloading of .pkpass pass files. In order to let your users download the .pkpass passes, you need to create web pages with hyperlinks in them that point to the .pkpass files. A simple HTML code file that serves a pass.pkpass to the user is displayed here:
<html><header><title>Passbook Site</title></header><body><ahref="http://localhost:8888/pass.pkpass">Download your pass here</a></body></html>
Note
