Update credit note
PATCH
https://api.light.inc/v1/credit-notes/{creditNoteId}
Updates a credit note in draft status. Fields sent as null clear the value; omitted fields remain unchanged.
Only in DRAFT (CREDIT_NOTE_CANNOT_BE_MODIFIED). The null rule in the description holds for description, currency, amount, documentNumber and the FX overrides only; companyEntityId, businessPartnerId, documentDate, areLinesWithTax and customProperties cannot be cleared — null leaves them unchanged. Changing businessPartnerId silently clears companyEntityId when the entity isn't one the new vendor is enabled for. documentDate also rewrites the posting date.
