The Xero API returned a contact with tax_number_type set to "TAXNUMBERTYPE/SSN", but the Python SDK only accepts these exact values: 'SSN' 'EIN' 'ITIN' 'ATIN' 'None' #205

I have been forced to monkey patch the SDK. Xero team can contact me to get the Tenant ID that generates this error.

original_setter = contact.Contact.tax_number_type.fset
def patched_setter(self, tax_number_type):
"""Setter that handles malformed tax_number_type from Xero API."""
if tax_number_type and isinstance(tax_number_type, str) and "TAXNUMBERTYPE/" in tax_number_type:
tax_number_type = tax_number_type.replace("TAXNUMBERTYPE/", "")
original_setter(self, tax_number_type)
