# accountant.changes.request

Accountants with corrections access only: ask the company to attach an existing receipt to a bank record (attach_receipt with entryId and receiptEntryId), match a receipt to a same-currency bank payment (settle_match with entryId and transactionId), or check which contractor a payment belongs to (contractor_attribution with contractorId and transactionId), with a reason and idempotency key. Nothing changes until a company administrator approves it; payouts, agreements and settings are never offered.

`POST /api/v1/accounting/accountant.changes.request`

Permissions: `accounting:read`, `accounting:write` · Roles:  · Idempotency key required

Not available over MCP: Accountants' corrections grant isn't offered over MCP yet: phase 1 is read and comment only.
