Hello @mike Jolley,
I have found this top through google as I am a TradeGecko user on woocommerce.
We are having issues with TG updating stock levels for 50 items, TG has informed me this is an issue with our woocommerce API giving errors.
I am also running wordfence security but cannot figure out why these 50 items will not receive stock level updates from TG?
Any advice is appreciated. We do have hooks setup for TG as you mentioned above?
