Hello,
I've tried to use https://developer.ebay.com/api-docs/sell/marketing/resources/item_price_markdown/methods/createItemP... endpoint to create a markdown promotion for multiple listings in an automated way, but when I send a valid request, eBay API always responds with a meaningless error:
'{"errors":[{"errorId":2003,"domain":"ACCESS","category":"APPLICATION","message":"Internal error","longMessage":"There was a problem with an eBay internal system or process. Contact eBay developer support for assistance"}]}'
I sent the following simple JSON:
'{"name": "80% off anything listed 42 months ago", "description": "80% off anything listed 42 months ago", "startDate": "2023-02-09T14:07:41.790Z", "endDate": "2023-02-10T13:07:41.790Z", "marketplaceId": "EBAY_MOTORS_US", "promotionStatus": "SCHEDULED", "promotionImageUrl": "https://via.placeholder.com/500", "selectedInventoryDiscounts": [{"inventoryCriterion": {"inventoryCriterionType": "INVENTORY_BY_VALUE", "listingIds": ["281658853283", "252194522766", "282321630671", "252728817103", "262918201691", "262937408596", "253346494083", "253355223901", "253510061649", "283405642715", "264325183487", "283487928421", "254246727456", "264343282712", "283509398006", "264417885788"]}, "discountBenefit": {"percentageOffItem": 70}}]}'
Is this API expected to work and can be used?
Also, where can I contact "eBay developer support"? I only found this: https://developer.ebay.com/support/developer-technical-support where it requires me to purchase a paid plan.
Do I really have to pay to report eBay APIs do not work like advertised?
Thanks,
Yurii
