Response to a prior request to pay or status request

Request

Communicates the status of a prior request to pay initiated by a customer of the partner.

An outboundRequestToPayResponse may indicate that a request to pay, sent to Electrum by the partner on behalf of a partner's customer, will be presented to the debtor, has already been paid or has failed for some reason. A new unsolicited outboundRequestToPayResponse may be received for each status update of the request to pay.

If the partner is unsure of the status of an outboundRequestToPay, an outboundRequestToPayStatusRequest may be used to solicit an up-to-date outboundRequestToPayResponse.

Headers

traceparentstring(traceparent)^[A-Fa-f0-9]{2}\-[A-Fa-f0-9]{32}\-[A-Fa-f0-9]...

A value used to trace an HTTP message within an Electrum Regulated Payments implementation. This field must be set as per the traceparent element defined in the W3C Trace Context Level 2 specification.

tracestatestring(tracestate)^[A-Za-z0-9=, _\*/@]{0,1024}$

A value used to provide context to an HTTP message as it is traced within an Electrum Regulated Payments implementation. This field must be set as per the traceparent element defined in the W3C Trace Context Level 2 specification.

Bodyapplication/jsonrequired

messageIdentifiersobject(MessageIdentifiers)required

Holds a point-to-point unique message identification string as well as a message's creation date time.

messageIdentifiers.creationDateTimestring(date-time)required

The date and time at which the message was created, in senders local timezone or UTC. The date must be formatted as defined by date-time in RFC3339

messageIdentifiers.messageIdentificationstring<= 35 charactersrequired

A reference used to unambiguously identify the message between the sending and receiving party. Take note that this uniquely identifies a single message in a potentially multi-message exchange to complete a payment.

supplementaryDataobject(SupplementaryData)

A list of key-value pairs to support adding any supplementary/additional data to an Electrum Regulated Payments API message.

originalMessageIdentifiersobject(MessageIdentifiers)required

Holds a point-to-point unique message identification string as well as a message's creation date time.

originalMessageIdentifiers.creationDateTimestring(date-time)required

The date and time at which the message was created, in senders local timezone or UTC. The date must be formatted as defined by date-time in RFC3339

originalMessageIdentifiers.messageIdentificationstring<= 35 charactersrequired

transactionIdentifiersobject(TransactionIdentifiers)required

Holds a series of identifiers to identify the transaction or an individual message that is part of a transaction.

transactionIdentifiers.endToEndIdentificationstring<= 35 charactersrequired

Unique identification, as assigned by the initiating party, to unambiguously identify the transaction. This identification is passed on, unchanged, throughout the entire end-to-end chain. Note: this is distinct from the UETR.

transactionIdentifiers.instructionIdentificationstring<= 35 characters

Unique identification, as assigned by an instructing party for an instructed party, to unambiguously identify the instruction. The instruction identification is a point to point reference that can be used between the instructing party and the instructed party to refer to the individual instruction. It can be included in several messages related to the instruction.

transactionIdentifiers.transactionIdentificationstring<= 35 characters

Unique identification, as assigned by the first instructing agent, to unambiguously identify the transaction that is passed on, unchanged, throughout the entire interbank chain. Usage: The transaction identification can be used for reconciliation, tracking or to link tasks relating to the transaction on the interbank level. Usage: The instructing agent has to make sure that the transaction identification is unique for a pre-agreed period.

transactionIdentifiers.uetrstring(UUID)required

Universally unique identifier to provide an end-to-end reference of a payment transaction. This identifier remains the same for all messages related to the same transaction.

The outcome of a prior outboundRequestToPayCancellationRequest operation

Request

Communicates the outcome of a prior outboundRequestToPayCancellationRequest operation.

An outboundRequestToPayCancellationRequest operation is not guaranteed to be successful. For example, if the associated outboundRequestToPay has already been paid then it cannot be cancelled.

Note too that if the associated outboundRequestToPay was rejected or has already expired then the outboundRequestToPayCancellationRequest operation will be deemed to have failed despite the net result of no subsequent payment. This is because the final status of the outboundRequestToPay will be something other than a cancellation.
