This specification provides the definition of the Authorization message (AUTHOR) to be used in Electronic Data Interchange (EDI) between trading partners, involved in administration, commerce and transport.

An Authorisation Message is sent by the Ordering Customer (or Payor or Agent on behalf of the Ordering Customer) or by a third party having authority on the Ordering Customer's payments to the Ordered Bank, to authorize the Ordered Bank to execute a given financial transaction.

This financial transaction might relate to both: multiple messages like PAYMUL and DIRDEB and single instruction messages like PAYORD and PAYEXT.

An Authorisation Message could also be sent from the Ordered Bank to the Ordering Customer or its Authorisation Authority to request authorisation for a given financial transaction.

Throughout this document the term 'Original Message' refers to the message to be authorised.

This message may be applied to both national and international settlements. It is based on universal practice and is not dependent on the type of business or industry.

• The authorisation carried by the message applies to the whole original message (i.e. to all instructions within the message.)
• A 'BANSTA' message could be sent in response to an Authorisation Message if the authorization cannot be given to the message. (e.g. 'Original Message Not Found')

See UNTDID, Part 4, Chapter 2.6 UN/ECE UNSM - General Introduction, Section 1.
