You need to log into the Walmart Developer Portal with your credentials to see the Analytics Dashboard. It provides a custom view for each seller to see their own API success rates and errors per object group.
You can view the success rates as a percentage of successful API calls for each API group (e.g. Items, Promotions, Orders) with the Analytics Dashboard.
The graph displays success rate for each API group you selected as a function of the time period you selected.
For each API object group, you can filter the percentage of errors by error type.
Use the Error drop-down to specify which error type you want to view percent errors.
In the object group, (e.g. Items), look at the API Errors column. This shows you the percentage of errors that this API group has for the error type selected, (e.g. 400 errors).
If Items shows 19.59%, this means that for all Item errors, 19.59% are due to 400 error type.
Walmart stores the feed information for a limited period of time, depending upon the feed type. If you call the feed status API outside of the retention time, you will get a 404 feed status error.
These are the retention days per FeedType:
Item 22 days
Price 25 days
Lag Time 25 days
Item Overrides 25 days
Promotions 25 days
Item Retire 25 days
Most common lag time feed errors are due to category-based lag time exceptions that are not approved for the particular category. To avoid these errors, you can revert asking to grant the approval, enable longer ship times or remove the lag time option for your SKUs.
Due to the current Covid-19 situation, some sellers add a few days as a buffer for their lag times. This causes some of their items to go over the allowed lag time, resulting in errors.
If a service provider has a different SKU for an item than the one that a seller has added, they will get 404 errors.
Two possible reasons for an Item 404 error:
Seller has a different SKU integrated for that item than the SKU that the service provider has.
Seller did not add that Item SKU to their Walmart catalog.
