listCatalogItems always return only 10 items #1253

Closed ouroboros25 closed 3 years ago

ouroboros25 commented 3 years ago

Hello! Using listCatalogItems method, I always get only 10 items in the payload array. Do you know how to change this limit, or how to get all others products?

Hello @ouroboros25. The v0 listCatalogItems operation was ported from the MWS Products API ListMatchingProducts operation. That operation has a max results size of 10.

From http://docs.developer.amazonservices.com/en_US/products/Products_ListMatchingProducts.html:

This operation returns a maximum of ten products and does not return non-buyable products.

@ouroboros25 The 2020-12-01 version of the searchCatalogItems operation now returns more results than the previous listCatalogItems v0 operation did: https://github.com/amzn/selling-partner-api-docs/blob/main/guides/en-US/use-case-guides/catalog-items-api-use-case-guide/catalog-items-use-case-guide_2020-12-01.md.

@chapmanjw is this actually true? I am still only seeing 10 results even after specifying page size to be 20

@ak5 The parameter is there, but as you have noted, it's not applying correctly. My team is working on fixing that bug. :-(

Hi @chapmanjw Is this bug fixed?

chapmanjw commented 2 years ago

@robinchen123 @ak5 The fix that was applied here is only applicable to the 2020-12-01 version of the Catalog Items API. The v0 API has a fixed limit of 10, whereas the 2020-12-01 version accepts the pageSize parameter. This fix was applied in August.

@chapmanjw I always get 40 different asins from 2020-12-01 version searchItem API though the result told me there are thousands of asins. Many asins are duplicate from the result of all pages and only 40 asins are different.

request url is /catalog/2020-12-01/items?keywords=tablet&marketplaceIds=ATVPDKIKX0DER&pageSize=20

@robinchen123 There is a known behavior "bug" (or feature, depends who you ask) where variation children in search results are rolling up to the variation parent. This gets weird in search results as you only see the parent, not knowing that the child is what actually matched the query and not knowing which child matched. We will be addressing this behavior in ~Q1 2022, but I don't have firm timelines on that yet.

The counts in the APIs are estimates of the total number of possible ASIN matches. For very broad queries, the API will only page through the first 1000 results.
