caaa.016.001.10

Q: What business area does caaa.016.001.10 belong to?

Card Payments - Acceptor to Acquirer ( caaa ).

Q: How do I validate a caaa.016 message?

Run askiso validate message.xml . The schema is found from the document's own namespace, so you do not name it. Validation needs that schema installed. To check the business rules without one, run askiso lint instead.

What caaa.016.001.10 is

caaa.016.001.10 is an ISO 20022 message definition. Its business area is Card Payments - Acceptor to Acquirer (caaa), and caaa.016 is the definition it versions.

AskISO does not copy the specification. The Registration Authority publishes the message definition report and the schema, free of charge. The links below go straight there.

This is one of 12 published versions of caaa.016, and it is not the newest. The current version is caaa.016.001.12. That does not make this page obsolete: a counterparty running an older integration may still send you exactly this version, and you will need to read it.

Versions of caaa.016
