GetSellerList response does not contain the variations for my multi-variation items. All other API calls return the variation nodes.
For GetSellerList to return the variations node in the response, you will need to send in the IncludeVariations to true when making the request.
Using this flag may degrade the call's performance, if your items contain many variations.. In such cases, when you use this flag, you may need to reduce the total number of items you're requesting at once. For example, you may need to use shorter time ranges in the EndTime or StartTime filters, fewer entries per page in Pagination, and/or SKUArray.
