Loan notes: we’re introducing a 10,000-byte limit on the
notesvalue accepted bysubmitUnderwritingNotesandattachLoanNote, taking effect no earlier than September 22, 2026. The limit is measured as UTF-8 encoded length. Plain ASCII text fits 10,000 characters; accented characters use 2 bytes each and most emoji use 4. Once enabled for your account, a longernotesvalue will return the error codeLOAN_NOTE_TOO_LONG, and the request will be rejected. Today, notes of any length are accepted via API request. We recommend truncating or splitting note content that exceeds the limit, and handlingLOAN_NOTE_TOO_LONGif you surface API errors to your users.
Fixed
- Loan notes: notes that exceed the underlying storage limit now return
LOAN_OPERATION_ERRORrather thanLOAN_INVALID_STATE, which more accurately describes the failure. This applies to all customers and is not gated by the rollout above.
