ISO 20022 Financial Message Parser & Validator API

Q: Which ISO 20022 message types are supported?

The engine natively supports pacs.008 (Financial Institutional Customer Credit Transfer), pacs.002 (Payment Status Report), pain.001 (Customer Credit Transfer Initiation), pain.002 (Customer Payment Status), camt.053 (Bank-to-Customer Statement), and camt.054 (Debit/Credit Notification).

Q: Does this handle FedNow and SEPA ISO 20022 implementations?

Yes. The parser adheres to SWIFT MX ISO 20022, EPC SEPA Rulebooks, and US Federal Reserve FedNow Service XML schemas.

Q: How is the Unique End-to-End Transaction Reference (UETR) extracted?

The parser automatically locates and extracts RFC 4122 UUID v4 UETR tags from PmtId/UETR elements across payment messages for global SWIFT gpi tracking.

Transform complex SWIFT MX, SEPA, and FedNow ISO 20022 XML payloads into validated, hierarchical JSON in sub-5ms pure compute.
