Amazon Product Advertising API - Get all OfferListingID's for ASIN
<p>As you know, it is possible that to find multiple offers for one ASIN on Amazon (different sellers), which byside compete to finally get the buy box. </p>

<p>Every offer for these ASIN has its unique OfferListingID, which makes it possible to address. But how can I get all the OfferListingID's for one ASIN?</p>

<p>Example Request:</p>

<pre><code>http://webservices.amazon.de/onca/xml?
    AWSAccessKeyId=[AccessKey]&amp;
    AssociateTag=[AssociateTag]&amp;
    IdType=ASIN&amp;
    ItemId=B00A6N2TKK&amp;
    Operation=ItemLookup&amp;
    ResponseGroup=Offers&amp;
    Service=AWSECommerceService&amp;
    Timestamp=2016-07-24T20%3A27%3A50Z&amp;
    Signature=[Signature]
</code></pre>

<p>The Response contains only one offer with its OfferListingID:<br>
The current buy box winner.</p>

<p>What I want to have is the OfferListingID for another seller, which supports Amazon Prime but is a bit more expensive. With the OfferListingID I will be able to address these specific seller for example a remote cart on my website.</p>

<p>If I work with parameter conditions=All <br>I get the right number of TotalNew (6) but TotalOffers is still 1 and should be 6 too:</p>

<pre><code>&lt;Item&gt;
  &lt;ASIN&gt;B00A6N2TKK&lt;/ASIN&gt;
  &lt;ParentASIN&gt;B00A6N2P4K&lt;/ParentASIN&gt;
  &lt;OfferSummary&gt;
    &lt;LowestNewPrice&gt;
      &lt;Amount&gt;###&lt;/Amount&gt;
      &lt;CurrencyCode&gt;EUR&lt;/CurrencyCode&gt;
      &lt;FormattedPrice&gt;EUR #,##&lt;/FormattedPrice&gt;
    &lt;/LowestNewPrice&gt;
    &lt;TotalNew&gt;**6**&lt;/TotalNew&gt;
    &lt;TotalUsed&gt;0&lt;/TotalUsed&gt;
    &lt;TotalCollectible&gt;0&lt;/TotalCollectible&gt;
    &lt;TotalRefurbished&gt;0&lt;/TotalRefurbished&gt;
  &lt;/OfferSummary&gt;
&lt;Offers&gt;
  &lt;TotalOffers&gt;**1**&lt;/TotalOffers&gt;
  &lt;TotalOfferPages&gt;1&lt;/TotalOfferPages&gt;
  &lt;MoreOffersUrl&gt;
</code></pre>

<p>Where is the problem in my logic? Is there another way to get a OfferListingID for an specific offer for an ASIN?</p>

<p>Thanks for your help!!!</p>
