Hi @Huptech-Web
Your answer is quite good (and I will accept is as the chosen answer).
However, it would have been better if I had been able to access this information within the useApi of the ui-extensions-react/checkout that I’m using in my extension. Ok, yes, I can access to metafields instead, but my app has been already installed by hundreds of clients (and I can’t ask them to reinstall it), so I can’t have that info from them.
