after reading step by step the tutorials on how to integrate a new channel within the woocommerce API and linnworks,
trying it over and over again, read and look on the internet for answers, everytime i get the same error "Error: Aucune donnée product spécifiée pour modifier product"
i cannot go to step 2 of channel integration woocommerce API, so that's why i ask some help because there is no related errors on the forums and the web which could help me.
Apologies for delayed response!
As i can see, your website is under construction. The error message might indicate, that Linnworks can not reach WooCommerce plugin because of the construction mode.
If turning construction mode off doesn't help, could you please create a new user for Linnworks support (you can use firstname.lastname@example.org email)? We can then try integrating WooCommerce from our end.
