I have a fully functional application that is working with the Ebay Browse API. It retrieves the response for a given SKU, (almost) perfectly matching the results returned in a standard ebay search.
However, it often misses items. It is not my filtering that is missing the items, it is missing from the API response. That is, they are missing even after paginating through all the existing results. I don't believe there is an error with my pagination, but maybe?
The listings that are missing seem random. They are often auction items, but also items where there are multiple selection options. However, not all auction items or items with selection options are missing.
Examples for missing items when searching industrial electronics for 6FC5203-0AF05-1AB1:
Both these items are missing in the browse API, along with many others. However when you search for them in Ebay, they are there.
I have tried every combination of things like location setting, shipping location options, etc. None of these changes the result.
A few missing items might be okay, but these items are often the ones with the best prices. If the browse API does not let me browse all existing listings, then it is useless.
relevant code:
api_url = "https://api.ebay.com/buy/browse/v1/item_summary/search?"
country_code = country.replace("EBAY-", "")
zip_code_us = f"19064"

print(country)

"Content-Type": "application/json",
"Accept": "application/json",
}
# Include selected countries in the API call

query_string = f"q={query}&limit=200&sort=newlyListed"
api_url += query_string
headers["X-EBAY-C-MARKETPLACE-ID"] = f"{country}"

if response.status_code == 200:

total_results = data.get("total", 0)
if total_results > 200:
print("Total results exceed 200. Paginating...")
all_items = []
for offset in range(0, total_results, 200):

api_url_with_offset = f"{api_url}&offset={offset}"
response = requests.get(api_url_with_offset, headers=headers)
if response.status_code == 200:

all_items.append(items_data)
else:
print(f"Failed to fetch items with offset {offset}")
return all_items, country
else:
return [data], country
else:
print(f"Failed to make API call for {country}")
return None
Any assistance would be appreciated.
