An **E-Invoice Field Mapping** controls how a Fenerum invoice is translated into the field schema your e-invoicing operator/intermediator expects (for example, OIOUBL in Denmark or Finvoice in Finland). Use these endpoints to inspect the configured mapping, fetch the list of fields available on your operator's schema, and save updates.
