[EDIT] Instead of using ReviseItem I switched to ReviseInventoryStatus which is the correct method. Not sure why I have been using ReviseItem calls for the last few years. I am either dumb or some part of the api or docs changed and I never caught on. https://ebaydts.com/eBayKBDetails?KBid=1641 [/EDIT]
I need to update the stock count on variation listings and I am not 100% clear what is required. I am using the C# .Net ebay sdk. I am able to ReviseItem for single items just fine.
ItemType item = new ItemType();
item.ItemID = itemId;
item.Quantity = qty;
StringCollection deletedFields = new StringCollection();
ReviseItemCall apicall = new ReviseItemCall(apiContext);
apicall.ReviseItem(item, deletedFields, false);
I provide the ebay item id and the new qty. Easy peasy. From what I understand from the developer docs the requirements for a variation listing ReviseItem is the ebay item id AND the SKU/Custom Label.
ItemType item = new ItemType();
item.ItemID = itemId;
item.Quantity = qty;
item.SKU = sku;
StringCollection deletedFields = new StringCollection();
ReviseItemCall apicall = new ReviseItemCall(apiContext);
apicall.ReviseItem(item, deletedFields, false);
However when I call this I get the following error.
eBay.Service.Core.Sdk.ApiException: 'Item level quantity will be ignored. The sum of the quantities for all the variations will be used for the listing quantity. Duplicate custom variation label.'
The customer label is not duplicated on this variation listing or in the entire store itself (which doesn't matter as far as I can see). What am I missing here? What else is required? I am 100% sure I am passing the correct ebay item id and customer labels to the sdk for updating.
