RELATED CONCEPT
UETR
UETR (Unique End-to-end Transaction Reference) is a UUID-based tracking reference that identifies a payment instruction across agents for investigation and status correlation.
FINANCIAL INFRASTRUCTURE CONCEPT
End-to-End ID
An end-to-end identification is a business reference assigned to identify a payment end-to-end across parties, distinct from clearing system references generated per hop.
Architectural context & analysis
ISO 20022 messages carry EndToEndId to help originators and beneficiaries reconcile statements and investigations.
It should remain stable for the business instruction even when technical message IDs change on retries.
Worked operational scenario
An ERP posts invoice 88421 as EndToEndId so camt.053 lines can match the original accounts-payable instruction.
Implementation considerations & controls
Do not overwrite EndToEndId on retry; use the idempotency key for technical deduplication instead.
