sg.fast.single — ISO 20022 pain.001 example for SG (instant-payment)

Singapore FAST credit in SGD, bank and branch codes, addresses on both parties.

A payment initiation file for SG on the instant-payment rail, shipped in pain.001.001.03, pain.001.001.09, generated and checked by pain001 0.0.70. It is a synthetic example built from the public scheme rulebooks: no real party, account or bank guideline behind it.

Files#

The twin is the same payment in the ISO 20022 Registration Authority's JSON convention, lossless in both directions; its JSON Schema (2020-12) is published per edition: pain.001.001.03, pain.001.001.09. An agent can produce a twin that validates against the schema and hand it to the library to render the XML.

Run it in your browser#

Open this scenario in the demo: the pain001 library loads in a Python runtime in your browser, rebuilds the file from the 1 record(s) below, checks it against the sg-fast rulebook and the official XSD, and shows the JSON twin. Nothing leaves your machine.

The flat records the library rebuilds it from (the CSV pipeline's own column names):
