Etsy

Description

The Etsy gem provides a friendly Ruby interface to the Etsy API

Installation

Installing the latest stable version is simple:

$ gem install etsy

If you want to be on the bleeding edge, install from GitHub:

$ git clone git://github.com/kytrinyx/etsy.git
$ cd etsy
$ rake install

Dependencies

The gem has been verified to work with version 1.5.0 of json. It will likely work with higher versions, but this is unproven.

Usage

Public Mode

The Etsy API has two modes: public, and authenticated. Public mode only requires an API key (available from http://developer.etsy.com):

require 'rubygems'
require 'etsy'

Etsy.api_key = 'foobar'

From there, you can make any non-authenticated calls to the API that you need.

Authenticated Calls

The Etsy API has support for both retrieval of extended information and write support for authenticated users. Authentication can either be performed from the console or from within a Ruby web application.

Console

For simple authentication from the console, configure the necessary parameters:

require 'rubygems'
require 'etsy'

Etsy.api_key = 'key'
Etsy.api_secret = 'secret'

First, generate a request token:

request = Etsy.request_token

From there, you will need to paste a verification URL into a browser:

Etsy.verification_url

Once you have allowed access, you can generate an access token by supplying the verifier displayed on the Etsy site:

access = Etsy.access_token(request.token, request.secret, 'abc123')

Authenticated calls can now be made by passing an access token and secret:

Etsy.myself(access.token, access.secret)

Web Application

The process for authenticating via a web application is similar, but requires the configuration of a callback URL:

require 'rubygems'
require 'etsy'

Etsy.api_key = 'key'
Etsy.api_secret = 'secret'
Etsy.callback_url = 'http://localhost:4567/authorize'

In this mode, you'll need to store the request token and secret before redirecting to the verification URL. A simple example using Sinatra:

enable :sessions

get '/' do
  request_token = Etsy.request_token
  session[:request_token]  = request_token.token
  session[:request_secret] = request_token.secret
  redirect Etsy.verification_url
end

get '/authorize' do
  access_token = Etsy.access_token(
    session[:request_token],
    session[:request_secret],
    params[:oauth_verifier]
  )
  # access_token.token and access_token.secret can now be saved for future API calls
end

Environment

The Etsy API has both a sandbox environment and a production environment.

If nothing is set, the default is :sandbox.

You can set this using:

Etsy.environment = :production

DSL

Use the Etsy::Request class to make flexible calls to the API.

To do so, find out which endpoint you wish to connect to and the parameters you wish to pass in.

>> access = {:access_token => 'token', :access_secret => 'secret'}
>> Etsy::Request.get('/taxonomy/tags', access.merge(:limit => 5))

or to fetch an associated resource

>> access = {:access_token => 'token', :access_secret => 'secret'}
>> Etsy::Request.get('/users/__SELF__', access.merge(:includes => 'Profile'))

or to limit the fields returned

>> shop_id = 'littletjane'
>> access = {:access_token => 'token', :access_secret => 'secret'}
>> Etsy::Request.get('/shops/#{shop_id}', access.merge(:fields => 'is_vacation,is_refusing_alchemy'))

Convenience Methods

There are some wrappers for resources that typically are needed in a small application.

Users

If you're starting with a user, the easiest way is to use the Etsy.user method:

>> user = Etsy.user('littletjane')
=> #<Etsy::User:0x107f82c @result=[{"city"=>"Washington, DC", ... >
>> user.username
=> "littletjane"
>> user.id
=> 5327518

For more information about what is available for a user, check out the documentation for Etsy::User.

Shops

Each user may optionally have a shop. If a user is a seller, he / she also has an associated shop object:

>> shop = user.shop
=> #<Etsy::Shop:0x102578c @result={"is_vacation"=>"", "announcement"=> ... >
>> shop.name
=> "littletjane"
>> shop.title
=> "a cute and crafty mix of handmade goods."

More information about shops can be found in the documentation for Etsy::Shop.

Listings

Shops contain multiple listings:

>> shop.listings
=> [#<Etsy::Listing:0x119acac @result={} ...>, ... ]
>> listing = shop.listings.first
=> #<Etsy::Listing:0x19a981c @result={} ... >
>> listing.title
=> "hanging with the bad boys matchbox"
>> listing.description
=> "standard size matchbox, approx. 1.5 x 2 inches ..."
>> listing.url
=> "http://www.etsy.com/view_listing.php?listing_id=24165902"
>> listing.view_count
=> 19
>> listing.created_at
=> Sat Apr 25 11:31:34 -0400 2009

See the documentation for Etsy::Listing for more information.

Images

Each listing has one or more images available:

>> listing.images
=> [#<Etsy::Image:0x18f85e4 @result={} ... >,
  #<Etsy::Image:0x18f85d0 @result={} ... >]
>> listing.images.first.square
=> "http://ny-image0.etsy.com/il_75x75.189111072.jpg"
>> listing.images.first.full
=> "http://ny-image0.etsy.com/il_fullxfull.189111072.jpg"

Listings also have a primary image:

>> listing.image
=> #<Etsy::Image:0x18c3060 @result={} ... >
>> listing.image.full
=> "http://ny-image0.etsy.com/il_fullxfull.189111072.jpg"

More information is available in the documentation for Etsy::Image.

Associations

Associations on resources can be specified with the 'includes' key.

A single resource can be specified with the name of the resource as a string:

>> Listing.find(1, {:includes => 'Images'})

Multiple resources can be specified with the name of the resources as a comma-delimited string:

>> User.find(1, {:includes => ['FeedbackAsBuyer', 'FeedbackAsSeller']})

If you want a more fine-grained response, you can specify the associations as an array of hashes, each of which must contain the name of the resource, and can also include the fields you wish returned, as well as the limit and offset.

>> association = {:resource => 'Images', :fields => ['red','green','blue'], :limit => 1, :offset => 0}
>> Listing.find(1, {:includes => [association]})

Github Flow

For those of you with commit access, please check out Scott Chacon's blog post about github flow

• Anything in the master branch is deployable
• To work on something new, create a descriptively named branch off of master (ie: new-oauth2-scopes)
• Commit to that branch locally and regularly push your work to the same named branch on the server
• When you need feedback or help, or you think the branch is ready for merging, open a pull request
• After someone else has reviewed and signed off on the feature, you can merge it into master
• Once it is merged and pushed to ‘master’, you can and should deploy immediately
