Yeah – you’ve got the idea.
So like, after an item is submitted to an online marketplace (ie: eBay/Amazon/Shopify/Etsy), either manually (using right click select Post To) or automatically post to social media the title, main picture, maybe super short (< 200 characters) description, and link to the marketplace listing.
The authorization requirement is totally expected and fine (at least for us, and not a big deal) – we have similar setups with BigCommerce, WordPress, etc for doing cross-submission of content.
If you would like some examples we’ve done in the past, I can dig some up and screen shot.
Thanks!
