This method lets you download a TSV_GZIP (tab separated value gzip) Item Group feed file. An item group is an item that has various aspect differences, such as color, size, storage capacity, etc. There are two types of item group feed files generated: <ul> <li>A daily Item Group feed file containing the item group variation information associated with items returned in the <a href="/api-docs/buy/feed/resources/item/methods/getItemFeed">Item</a> feed file for a specific day, category, and marketplace. (feed_scope = <code>NEWLY_LISTED</code>)</li> <li>A weekly Item Group Bootstrap feed file containing all the item group variation information associated with items returned in the <a href="/api-docs/buy/feed/resources/item/methods/getItemFeed">Item Bootstrap</a> feed file for all the items in a specific category. (feed_scope = <code>ALL_ACTIVE</code>)</li> </ul> Note: Filters are applied to the feed files. For details, see <a href="/api-docs/buy/static/api-feed.html#feed-filters">Feed File Filters</a>. When curating the items returned, be sure to code as if these filters are not applied as they can be changed or removed in the future. The contents of these feed files are based on the contents of the corresponding daily Item or Item Bootstrap feed file. When a new Item or Item Bootstrap feed file is generated, the service reads the file and if an item in the file has a primaryItemGroupId value, which indicates the item is part of an item group, it uses that value to return the item group (parent item) information for that item in the corresponding Item Group or Item Group Bootstrap feed file. This information includes the name/value pair of the aspects of the items in this group returned in the variesByLocalizedAspects column. For example, if the item was a shirt some of the variation names could be Size, Color, etc. Also the images for the various aspects are returned in the additionalImageUrls column. The first line in any feed file is the header, which labels the columns and indicates the order of the values on each line. Each header is described in the <a href="/api-docs/buy/feed/resources/item_group/methods/getItemGroupFeed#h3-response-fields">Response fields</a> section. <h3>Combining the Item Group and Item feed files</h3> The Item Group or Item Group Bootstrap feed file contains details about the item group (parent item), including the item group ID itemGroupId. You match the value of itemGroupId from the Item Group feed file with the value of primaryItemGroupId from the corresponding daily Item or Item Bootstrap feed file.<h3>Downloading feed files </h3> Item Group feed files are binary gzip files. If the file is larger than 100 MB, the download must be streamed in chunks. You specify the size of the chunks in bytes using the <a href="#range-header">Range</a> request header. The <a href="#content-range">content-range</a> response header indicates where in the full resource this partial chunk of data belongs and the total number of bytes in the file. For more information about using these headers, see <a href="/api-docs/{swift-folder}/buy/static/api-feed_beta.html#retrv-gzip">Retrieving a gzip feed file</a>. Note: A successful call will always return a TSV.GZIP file; however, unsuccessful calls generate errors that are returned in JSON format. For documentation purposes, the successful call response is shown below as JSON fields so that the value returned in each column can be explained. The order of the response fields shows the order of the columns in the feed file. <h3>Restrictions </h3> For a list of supported sites and other restrictions, see <a href="/api-docs/{swift-folder}/buy/feed/overview.html#API">API Restrictions</a>.

category_idstringrequired

An eBay top-level category ID of the items to be returned in the feed file. The list of eBay category IDs changes over time and category IDs are not the same across all the eBay marketplaces. To get a list of the top-level categories for a marketplaces, you can use the Taxonomy API <a href="/api-docs/commerce/taxonomy/resources/category_tree/methods/getCategoryTree">getCategoryTree</a> method. This method retrieves the complete category tree for the marketplace. The top-level categories are identified by the categoryTreeNodeLevel field. For example:   <code>"categoryTreeNodeLevel": 1</code> For details see <a href="/api-docs/buy/buy-categories.html">Get Categories for Buy APIs</a>. </li> </ul> Restriction: Must be a top-level category other than Real Estate. Items listed under Real Estate L1 categories are excluded from all feeds in all marketplaces.

datestring

The date of the daily Item Group feed file (feed_scope=<code>NEWLY_LISTED</code>) you want. The date is required only for the daily Item Group feed file. If you specify a date for the Item Group Bootstrap file (feed_scope=<code>ALL_ACTIVE</code>), the date is ignored and the latest file is returned. The date the Item Group Bootstrap feed file was generated is returned in the Last-Modified response header.</code> The Item Group feed files are generated every day and there are 14 daily files available. There is a 48 hour latency when generating the files. This means on July 10, the latest feed file you can download is July 8. Note: The generated files are stored using MST (US Mountain Standard Time), which is -7 hours UTC time. Format: <code>yyyyMMdd</code> Requirements: <ul> <li>Required only when feed_scope=<code>NEWLY_LISTED</code> </li> <li>Must be within 3-14 days in the past</li> </ul>
