Error code : 83
When synchronizing products, sometimes you encounter this error “The term ‘GTC’duration is not available for this type of listing” or “The term ‘GTC’duration is not available for xxxxx category”.
eBay API refused this listing because context did not allow to use the GTC duration. This may be linked to your eBay account, targeted category, or any other reason link to your eBay account. For more information on GTC, please read here.
You must configure in the first “Settings” tab under “Listing duration” to 10 days.
