Changelog

Loan application number: The loan object on an order now accepts an application_number (the POS file number) as an alternative to loan_number. A loan must supply at least one of the two identifiers; loan_number is no longer required on its own. The new field is returned in the loan object on order create, retrieve, and list responses, so if you validate responses against a strict schema, update it to allow application_number.

This supports POS-first workflows where the file exists before the LOS has assigned a loan number. If you currently send a placeholder in loan_number, we recommend moving that value to application_number and populating loan_number only once the real one is assigned. In the near future, loan_number will no longer be editable once set, and attempts to change it will be rejected. That change will be announced separately.

See the Loan object reference for the full loan schema.
