Passbook manages boarding passes, movie tickets, retail coupons, & loyalty cards. Using the PassKit API, developers can register web services to automatically update content on the pass, such as gate changes on a boarding pass or adding credit to a loyalty card.

Apple provides a specification for a REST-style web service protocol to communicate with Passbook, with endpoints to get the latest version of a pass, register / unregister devices to receive push notifications for a pass, and query for passes registered for a device.

Rack::Passbook provides those specified endpoints.

• Ruby 1.9 or higher
• PostgreSQL 9.1 or higher

gem 'rack-passbook', require: 'rack/passbook'

Rack::Passbook can be run as Rack middleware or as a single web application. All that's required is a connection to a Postgres database.

An example application can be found in the /example directory of this repository.

require 'bundler'
Bundler.require

run Rack::Passbook

What follows is a summary of the specification. The complete specification can be found in the Passbook Web Service Reference.
