Carriage

Carriage is a Ruby wrapper to Amazon's Cart Form functionality. Gem helps add any number of items to customer's shopping cart and direct him to Amazon website to complete order.

To use this gem, you will eventually require Amazon's AssociateTag, so consider to register first with Amazon Associate program and become more familiar with it.

Programmatic access to product data is out of scope for this gem, but I recommend to use vacuum gem if there is such a need.

Battle tested at aShop

Add this line to your application's Gemfile:

gem 'carriage'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install carriage

A lot of examples could be found in tests

There are basically two ways to use this gem bare metal and with builder. Let's start off with baremetal:

Carriage.call(:us, {
  AssociateTag:'tag', 
  "OfferListingId.1": "B00WR23X5I", 
  "Quantity.1": 1 
 }
)

The only thing it will validate, is a presence of locale. All other parameters will be converted by URI.encode_www_form without any verification. Be carefull!

Library also offers a simpler interface that tries to valide data with convinince methods on top.

items = [
 {Id: '123123'}.
 {ASIN: '1231234', quantity: 2}
]

Carriage.build(items, tag: 'my_attribution_tag', locale: :uk)

• Every item should be a hash, with ASIN or ID (short for OfferListingId) key provided. All keys are case insensitive.
• By default quantity is 1, feel free to rewrite that.
• Carriage.build also requires :tag attribute (short for AssociateTag)
• Defaults to locale: :us, if no other locale was provided.

All locale are based on a two letter country codes - ISO 3166-1 alpha-2. Here is an exact mapping:

• Ask specific questions about the API on the Amazon forum.
• Report bugs and discuss potential features in GitHub issues.
