# invoices.actionReview

Review an exact invoice action before confirming it. Pass action and its input fields, including the current expectedRevision. Returns complete invoice lines, taxes and currency totals, exact delivery recipients and message, dates, masked receiving methods, proposed payment or tax changes, effects and blockers. Show these records and consequences to the person. For issue, send, remind, approve, schedule, void, write-off, payment recording/removal and tax correction, MCP and Ask AI must pass the returned reviewHash with the same action/input after explicit human approval. A changed invoice, company, customer or payment source requires a fresh review. This read does not issue, send, schedule or record anything.
