CT-e

Service disagreement

Registers event 610110 (service disagreement) on a CT-e issued by another company.

POST/openapi/v2/empresas/{empresaId}/cte/{chaveAcesso}/desacordo

Requires the token, timestamp and sign signature headers, see Authentication.

This company acts as receiver / taker of a CT-e issued by someone else: the path carries the 44-digit access key of the other party document and the event is routed to the SEFAZ of that document state. Sent synchronously; on success the event object is returned. Keep the protocolo: it is the protocoloEvento used by Cancel service disagreement.
