Summary

Updates an existing Fakturownia invoice by ID, applying the fields supplied as a JSON object.

Inputs

  • Invoice ID (required) — The numeric ID of the invoice to update.
  • Update Fields (JSON) (required) — A JSON object of fields to send with the update. The node parses this value and combines its properties with the invoice ID; invalid JSON causes an operation error.

Output shape

One or more n8n items containing the parsed MCP tool result.

The node calls the update_invoice tool once per input item. If the result is an array, each element becomes an output item; otherwise it emits one item. Non-JSON text is returned as { "rawText": "…" }. With Continue On Fail enabled, errors are emitted as { "error": "…" } items.

Examples

Example 1: Update an invoice's notes

Set Invoice ID to the target invoice and Update Fields (JSON) to an object such as {"description":"Updated notes"}. The JSON properties are sent alongside the invoice ID.
