How to obtain tax number information in orders from Mexico

[Foxfur]

Ok I managed to fix the bad request issue I had and indeed if you query

localizedFields(first: 100) {
    nodes {
          title
          value
     }
}

on the order object, you will indeed get the RFC number on Mexican orders, but you need to switch to the 2025-01 version of the API, since it’s a change that has only just been introduced at the beginning of this year.

Hope it works for you!
