/abort

Request body:

Field	Type	Required	Format / constraints
documentExtID	string	Yes	Mandatory
docTime	string	No	yyyy-MM-dd HH:mm:ss
docNumber	string	No	External document number
amount	integer (int64)	No	Minor units

Only documentExtID is used to locate the document in the current implementation. docTime, docNumber and amount are retained for contract compatibility but do not affect the operation.

Success response:

Field	Type	Required	Notes
documentID	integer (int64)	No	Internal document id
documentExtID	string	No	External document id

/abort releases every terminal operation of the document: pending operations are aborted, hanging cancels are finished, and every already charged payment is reversed. If any of them cannot be undone, /abort answers with an error and keeps the document — retry it, and do not treat the receipt as cancelled.
