Ruby API for accessing the USPS WebTools API found here: www.usps.com/business/webtools.htm
PDF Guides can be found here: www.usps.com/business/webtools-technical-guides.htm
Usage of this library assumes you already have a USPS API account and that all priviledges have been granted.
Project Status - Looking for a Maintainer
This code is no longer properly maintained as I'm no longer with the company it was developed for. If you're using it and would be interested in maintaining it please send me a message and I can get you set up.
Exposed API Calls
The following USPS API calls are currently exposed through this library:
<AddressValidateRequest> -- USPS::Request::AddressStandardization <CityStateLookupRequest> -- USPS::Request::CityAndStateLookup <ZipCodeLookupRequest> -- USPS::Request::ZipCodeLookup <TrackRequest> -- USPS::Request::TrackingLookup <TrackFieldRequest> -- USPS::Request::TrackingFieldLookup <DeliveryConfirmationV3.0Request> -- USPS::Request::DeliveryConfirmation (for production) <DeliveryConfirmCertifyV3.0Request> -- USPS::Request::DeliveryConfirmationCertify (for testing)
Using the library is as simple as building a new USPS::Request:: object, calling #send! and using the response. For example, to send a tracking request you'd do the following:
request = USPS::Request::TrackingLookup.new(tracking_number) response = request.send! response.summary response.details
The library assumes that either ENV is set, or that you set USPS.username to your USPS API username.
See the individual USPS::Request classes for details on how to use them.
USPS API Certification
Part of the process of setting up an account with the USPS API is to run certain tests against the USPS API. This library has all the requisite tests built in, runnable with rake:
USPS_USER="[username]" rake certify
or as an installed gem:
USPS_USER="[username]" ruby -rubygems -e "require 'usps/test'"
If any of the tests fail, you don't have access to that API and may need to work with USPS to fix it.
Note on Patches/Pull Requests
Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
