I've ran into an issue that data returned from amazon had different property names ('TinyImage' vs 'tiny_image') -- that caused me to write a lot of hacks and wordarounds to deal with. While i expected asin library and code seemed reasonable, i was really puzzled why would amazon do such a thing with me (or us) :D
But I think that this weirdness is explained by one of dependencies used in this project, it has a code like this:
https://github.com/jnunemaker/crack/blob/master/lib/crack/util.rb
I don't think that altering objects is a good idea for any Xml serialization library. So maybe it's a good opportunity to change dependency to something like multiXml ( https://github.com/sferik/multi_xml ) ?
When doing a search_keywords for an ISBN number (e.g. for 0471317519) I receive the following error:
NoMethodError: undefined method `each_pair' for ["ASIN", "0471317519"]:Array
After a bit of investigation here is what I've found:
when TotalResults > 1 then response['ItemSearchResponse']['Items'] is a an array of hashes
when totalResults == 1 then response['ItemSearchResponse']['Items'] is a single hash
From what I can tell, ASIN will cease to function once Amazon disables API 4.0, which seems to be scheduled for the end of October, 2019.
https://webservices.amazon.com/paapi5/documentation/?ref_=pe_27042120_428145790
Any plans to update ASIN to use new the API?
Hi there,
My app has a Configuration.rb model. Short of renaming it, how can avoid the clash with ASIN::Configuration?
When I comment out the contents of asin.rb (to allow the app to start), enter the rails console, and type ASIN:Configuration, I see:
Configuration(id: integer, name: string, cached_slug: string, model_id: integer, configured_ram: float, requires: string, created_at: datetime, updated_at: datetime)
These are the attributes of my app's existing Configuration model, not ASIN:Configuration.
Many thanks,
Steven.
I am using product advertising api for fetching amazon products. API returns product from different store.
I want to fetch products from my store only.
Let say "ABC" is my amazon store and I want to fetch all products belongs to "ABC" only.
Please help me.
In your doco you say this:
items = client.lookup '1430218150'
items.first.item_attributes.title
=> Learn Objective-C on the Mac (Learn Series)
BUT if you execute that it fails saying 'item_attributes' method undefined.
What is the set of methods you can call on a returned item given they are not defined on the SimpleItem class?
Hi !
The version of asin found on RubyGems still depends on
HTTPI ~> 0.9
which breaks other Gems such as savon (soap client) which requires
HTTPI ~> 1.0
Can you please push an updated version (its already changed in master I think) ?
Thx
I'm having a weird issue.
I have the following file in the lib folder of my Rails App:
require 'asin'
module YoofersAsin
# set up a client to talk to the AWS REST API
@client = ASIN::Client.instance
def self.search keywords, index = :All, response_group = :Large
begin
@client.search(:Keywords => keywords, :SearchIndex => index, :ResponseGroup => response_group)
rescue HTTPClient::ConnectTimeoutError
[]
end
end
def self.format_result_for_dropdown results
results.map { |item| { title: item.title, price: item.formatted_amount, image_url: item.image_url, url: item.details_url } }
end
# as long as the max is less than the min, it can be ignored
def self.limit_price_range results, min = 100, max = 200
if max <= min
results.select { |each| each.amount >= min }
else
results.select { |each| each.amount >= min && each.amount <= max }
end
end
def self.autocomplete keywords, index = :All, response_group = :Large
results = self.search(keywords, index, response_group)
results = self.limit_price_range results
self.format_result_for_dropdown results
end
end
require 'hashie'
module ASIN
class SimpleItem
def formatted_amount
@raw.ItemAttributes!.ListPrice!.FormattedPrice
end
end
endI'm calling it from a controller like this:
class AmazonSearchController < ApplicationController
respond_to :json
def index
@response = YoofersAsin.autocomplete(params[:term])
respond_with(@response)
end
endWhen I call the index action of the controller I get the following error:

The weird part is that if I go to the rails console and call the same method as I do in the index action, I get the results just fine.
My initializer looks like this:
ASIN::Configuration.configure do |config|
config.secret = "***********"
config.key = "************"
config.associate_tag = "*********"
end
require 'httpi'
HTTPI.adapter = :httpclient
HTTPI.logger = Rails.loggerI'm running ruby '1.9.3' and rails '3.2.8'
So, 'rails c' works, 'rails s' does not! very odd!
Any ideas?
Dear Associate,
We have an important update for you regarding the Amazon Product Advertising API.
Certificate Authorities (CAs) and companies such as Google and Microsoft are retiring support for SHA1 as a hashing algorithm used to sign SSL/TLS certificates (for more information, please read the CA/Browser Forum post). Because of this, the Amazon Product Advertising API will also be retiring use of SHA1 for digital signatures in SSL/TLS certificates and will be upgrading to SHA256 by October 09, 2015. This means that customers accessing the Product Advertising API via HTTPS will need to make sure they’re using the latest certificate bundles on their client machines.
The questions below should help you ensure you’re ready when we switch to SHA256:
- What action do I need to take?
You need to verify if your applications are compatible with our new certificate. Simply run an API request to one of the following testing endpoints:
US https://sha256.webservices.amazon.com/onca/xml
If you are able to run the request successfully, your software is compatible with our new certificates.
- I was able to get a successful response using the testing endpoint. What do I do now?
Nothing! If your application was able to get a successful response using the testing endpoint, then you will be able to access the API even after the SHA256 migration.
- I was unable to get a response using the testing endpoint. What do I do now?
If you were unable to get a response using the testing endpoint, then you will have to ensure you are using more recent libraries of the programming/scripting language to access the API. For compatibility, the client libraries will require the following:
Java: Requires JDK 1.6.0_19 or later.
PHP: Requires OpenSSL 0.9.8o or later.
C#: No change.You can update the certificate bundle in your browser simply by updating your browser. Instructions for the most common browsers can be found on the browsers’ websites: Chrome, FireFox, and Safari. Certificate bundles for Internet Explorer are managed by the Windows OS, so ensure that you update the OS as well.
If you need development support beyond the above suggestions, please post your questions to the Product Advertising API forum under the Advisory: Product Advertising API to switch to SHA256 Hash Algorithm thread. Many experienced members of the Amazon Associates program regularly participate in the forums.
- Do I need to update the endpoint for accessing Product Advertising API to the above listed endpoints?
No, the listed endpoints are only for testing purposes and will be discontinued post migration.
- By when do I need to make the change/ update?
You can do this change at any time on or before October 09, 2015. Any changes you make will be compatible with our existing URL(s).
Thank you for your understanding and cooperation.
The Amazon Product Advertising API team.
When trying to access the various browse nodes, it appears mash is assigning the BrowseNode values on the same key (BrowseNode)
I'm having an exceptionally difficult time handling calls that result in errors. There has to be an easy way to do this.
Could anyone please help enlighten me?
Using code like the following, I'm pulling down a list of books.
t = tags.collect {|x| x.name}
client = ASIN::Client.instance
books = (client.search_keywords t)
Works great, except that sometimes it grabs a book like this one: http://www.amazon.com/Lasers-Lynn-Myring/dp/0613769902%3FSubscriptionId%3DAKIAINAJKLF3WOPY77OA%26tag%3Dwha07-20%26linkCode%3Dxm2%26camp%3D2025%26creative%3D165953%26creativeASIN%3D0613769902
which doesn't have an image, so it displays poorly on my page. I could set a 'default' image, but overall, I'd just rather not retrieve ones without an image. Is this possible, or does the Amazon API (or the gem) not allow that?
Hi!
Is it possible to change the language dynamically for the amazon results? I only get US-results at the moment and I also like to receive german results.
How could I change your gem to provide this feature also? Any suggestions?
Best regards.
Matthias
Hey, thanks for making this gem. newbie here.
I was able to get up and running with the gem and able to fetch the Item details. But "item_attributes" does not seem to have images to it. Is there a way I can pull images ?
Thanks again.
require 'asin'
ASIN::Configuration.configure do |config|
config.secret = 'SG7Z6LG8SxLk4vTC*********+s/hqOThFhOb'

end
client = ASIN::Client.instance
book = client.search(:Keywords => 'William W. Purkey', :SearchIndex => :Books).first
result call back is book "From Conflict to Conciliation: How to Defuse Difficult Situations by William W. Purkey, John J. Schmidt and John M. Novak".
I can get title, details_url, but image_url is nil. IN result I see "LargeImage=#Hashie::Mash>>", BUT in website search I see it have image

I just migrated from Thin to Unicorn, everything's working except ASIN. I'm getting the following error, do I need to configure an "after_fork" method or something in order for ASIN to work with Unicorn?

By default, httpi uses excon, but there can be version-related issues between these two libraries, causing Amazon to report that the Signature does not match. By changing to curb, this problem disappears. It may be the case that the correct combination of versions works, but I was not able to determine the correct combination. This can be done by adding 'require "curb"' prior to the 'require "asin"' command.
Adding SearchBins Response Group return only ASINS and PARENT_ASINS but not Search Bins.
For example
request:
@search = @client.search SearchIndex: :Baby, Keywords: 'pants', ResponseGroup: :SearchBins
Response:
[{"asin":"B016YZGI5K","parent_asin":"B00UZRKZTE"},{"asin":"B00XZ19MS2","parent_asin":"B00YFD0SGE"},{"asin":"B0133JD07Y","parent_asin":"B0133JAE8W"},{"asin":"B017NT1UFY","parent_asin":"B017NT1F4A"},{"asin":"B00PZVDFDI","parent_asin":"B00PZVCI8Q"},{"asin":"B012TV6920","parent_asin":"B00JABR8KA"},{"asin":"B017NT234G","parent_asin":"B017NT1HH0"},{"asin":"B017NT1U6S","parent_asin":"B017NT1FCC"},{"asin":"B0133JEGO0","parent_asin":"B00LAYTVJQ"},{"asin":"B012U6XCV0","parent_asin":"B00JABR8LO"}]
As asin uses httpi, I presumed one could disable the default stdout logging using:
HTTPI.log = false
However this does not suppress the lookup response output. Is there some other setting one could use to suppress this output? It is of course useful for debugging but otherwise unnecessary.

Ruby 1.9.3p392, Rails 3.2.13, I get the following error on some products:

The line that causes it is this:
@Items = client.lookup @item.asin
client is client = ASIN::Client.instance
I'm using the asin gem (https://github.com/phoet/asin) to make requests to Amazon Product API.
It has been working well for a whole year but a few days ago without making any changes I started noticing the same product API requests now return the following error:

The original request still works, so I'm assuming that some changes on Amazon product API made the asin gem incompatible:

Hey, many thanks for this gem. I've been able to use it to query the Amazon API by manually loading it into IRB. When I tried to load it into my rails application I ran into some problems though.
Not sure if I'm doing it wrong or not. Here is what I have:
config/initializers/asin.rb:
require 'asin'
include ASIN
configure :secret => '', :key => ''
and when I start the rails app (rails s or rails c) I get a stackdump starting with:
/opt/ruby-enterprise-1.8.7-2010.02/lib/ruby/gems/1.8/gems/asin-0.0.8/lib/asin.rb:91:in `merge!': can't convert Class into Hash (TypeError)
I'm done working for the night, but tomorrow I'll probably crack open the gem and see what I can find.
I was checking this out and I see that the example is incorrect.
access the internal data representation (Hashie::Mash)
item.raw.ItemAttributes.ListPrice.FormattedPrice
=> $39.99
If you are following along with the previous examples (VERY helpful for noobs), the proper syntax is:
items.first.raw.ItemAttributes.ListPrice.FormattedPrice
when i look some asins like B00X4WSLS4 it does not return me price anywhere how i can lookup its price and all colors?
Currently I can get the list price or the lowest new price but the lowest new price doesn't include shipping. Does anyone have any idea as to how I can get the lowest new price including shipping?
Edit: Apparently, due to a recent change, Amazon no longer offers the ability to grab the lowest price via their API. I just wanted to update this comment in case anyone is running into the same problem as I was. I solved it by using Nokogiri to scrape the product details page for the price.
This code:
https://gist.github.com/880611

Hi,
I've been using the asin gem for months without any problems but now all of a sudden I get these errors on all my api calls:
SignatureDoesNotMatchThe request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.eb0458ea-0d4c-42ea-bd0b-4ba3b8eddc79'
These are the params I'm sending:
D, [2017-08-01T13:34:02.116024 #9058] DEBUG -- : calling with params={:Keywords=>"pampers baby dry 2 22", :SearchIndex=>"Baby", :Operation=>:ItemSearch}
I, [2017-08-01T13:34:02.116742 #9058] INFO -- : performing rest call to url='http://webservices.amazon.de/onca/xml?AWSAccessKeyId=AKIAJMVM7ENHSE65I23Q&AssociateTag=i0616-21&Keywords=pampers%20baby%20dry%202%2022&Operation=ItemSearch&SearchIndex=Baby&Service=AWSECommerceService&Timestamp=2017-08-01T11%3A34%3A02Z&Version=2011-08-01&Signature=9zSE%2BHIFFqYR5PUnOHf%2Fpwmb3NtShIB5y8zevGhtccw%3D'
I didn't change anything (I think) and I've made several new access key id's and they all give the same error.
I think it has to do with the %2B (+) and %3D (=) in the signature which must be some kind of character encoding thingy going wrong...
Thnx!

I found that the search function for some queries frequently returns REXML::ParseException error. The issue is especially severe on Heroku Cedar stack (for unknown reason). And it only happens for some queries. I'm suspecting that there are some issues with parsing the XML response.
The following is my code:
client = ASIN::Client.instance
client.search(:Keywords => "Shark Tale", :SearchIndex => :UnboxVideo, :ResponseGroup => :ItemAttributes)
And the following is the error I'm seeing. It rarely fails on my local machine, but it shows up frequently on heroku:
REXML::ParseException: #<NoMethodError: undefined method `[]' for nil:NilClass>

An example where this issue doesn't occur is with a slightly different query
client.search(:Keywords => "Shark Tales", :SearchIndex => :UnboxVideo, :ResponseGroup => :ItemAttributes)
The amazon product API appears to support similar products but I don't see support for it in ASIN. Is this something you are intending to add support for?
Could be just the same as paperclip: http://www.icyte.com/saved/rdoc.info/457604
ASIN's read me talks about:
config.secret = 'your-secret'
config.key = 'your-key'
config.associate_tag = 'your-tag'
Amazon's Product API website talks about:
Secret Key
Access Key ID
Associate ID
Are these the same thing? (I can't test this myself due to the other issue I just reported via your GitHub page.)
If they are the same, I'll fork the gem, edit the 'read me' to what follows, then submit a pull request:
config.secret = 'your Secret Key'
config.key = 'your Access Key ID'
config.associate_tag = 'your Associate ID'
How do I turn off the debug info?
get rid of the pluggable backends and just use Hashie::Rash
/cc @kurtfunai
Hi.
In the current version of Hashie, Rash is used for a regular expression-based hash, and the Rash gem's definitions of Rash gets overridden by the Hashie Gem's own. wzcolon has forked the gem to use a new namespace for the class. (Hashie::Hash::Rash, see https://github.com/wzcolon/rash.)
Would you accept a pull request to point at the new version of Rash? The tests currently pass but moving forward to the current version of Hashie is required for some other products.
