Because I couldn't find any other article in the whole world wide web that had a working solution. My use-case here is that I have built an eBay integration between Zoho Inventory and... eBay. Out-of-the-box, and at-time-of-print, Zoho Inventory only syncs eBay one way, in other words, listings on eBay get downloaded to Zoho Inventory but not vice-versa. Then there's an added delay of 4 hours. Then item specifics in eBay's listings don't get parsed into custom fields in Zoho Inventory... and the list goes on. So in my job, we tend to create a few custom functions which will download any item from eBay to Zoho Inventory and vice-versa. Easy to make the function to push an item to an eBay listing (see my other articles for this). But we also want to push an image from Zoho Inventory to eBay.
