Thanks for your reply. Nothing changed unfortunately. I’m not 100% clear on how to use the exclude functions but I tried with “Items” as the Gettext String and “woocommerce” as the Domain. I also tried having the domain blank. But it didn’t work.
I think that key values in the json object should never be translated anyway. Also the fact that wordpress creates the authentication key with a “wrong” json (with the gettext string) but sends to my server the “correct” json (just saying Items for the key) is also a bit strange.
