We are selling on shopify, amazon and eBay, using CODISTO it is synchronizes great and they are also great!
We are selling underwear so there are a lot of variations for each model/style.
So I have a question if there is a way to push only the active variations form Shopify to eBay without pushing the whole listing with 70 variations?
as also if there is a possibility to make for the individual variation a best offer option?
eBay doesn't offer a simple way to achieve this via API due to their 'restricted revise' protection.
Therefore the only way we can suggest to achieve currently is to set the inventory level for those variants on eBay to 0 (i.e. the 0 value is specific for eBay and 'unlinked' from your Shopify inventory level).
If that will work, you can do that by going to single edit mode, clicking on the product and "Edit Variation Quantities". Note this isn't achieable via multi edit currently.
