The business partner the document is issued to. Re-pointing it to a different partner re-derives every partner-dependent value from the new partner: documentAddress, project, language, taxation, tax rates, payment method and terms, VAT ID, delivery terms, shipping method, preferred warehouse, sales representative, editor, and the line item discounts. Line item prices and the document currency are deliberately kept unchanged, so negotiated prices survive the change. Fields sent in the same request take precedence over the derived values; a project sent alongside also replaces the one the new partner would bring, and the project-dependent values derive from it. Passing the id the document already has has no effect. Write-protected documents are rejected.

Editor information

List of tags associated with the document. The passed list replaces the currently associated tags.

Custom field values for the document. Only custom fields configured for this document in your Xentral instance are accepted here; the customField1 to customField40 keys exist on line items only. Listed keys are written, keys that are not listed are left untouched. Pass value: null to clear a single field.

Sales information

Line items to write together with the credit note. An entry with an id updates that product line item of this credit note (only the provided fields), an entry without an id creates a new line item appended at the end, and an entry with deleted: true deletes the referenced line item. Line items not included in the list are left unchanged - only an explicit deleted entry removes one. Intermediate line items (ids prefixed with il-) can be updated inline as well, limited to their name and description; creating or deleting them requires the dedicated line-item endpoints.
