OAuth scope: supplier_invoice.write
Reverts a supplier invoice from paid. Precondition: current status must be paid. On success, status is to_review and payment_date is cleared (null). Otherwise 400 Bad Request (invalid transition).
Idempotency and retries: There is no separate idempotency key; the outcome depends on the invoice’s current status. Only paid invoices accept this action. After a successful unmark, status is to_review, so a second call returns 400 (invalid transition), not 200.
Bearer authorization header: Bearer <token>, where <token> is the access token received from the authorization server at the end of the OAuth 2.0 flow.
Required only for Sandbox API requests; to get one, please sign up to the Developer Portal.
