Hey @Luca_Pinasco
Thanks for your patience while I looked in to this. For context on the field, this is a field in the admin where a customers’ tax details can be added, however it’s not currently available through the API.
Can you share more details on how you were planning to use this field? I would like to pass that on to the product teams so they have a better understanding on how this would be used if they do make it available in the future.
