Changes to the Paytrim API, newest first. Additive changes — a new endpoint or a new
field in a response — are made without notice, so build your integration to ignore
fields it does not recognise. Anything that would break an existing integration is
communicated to you in advance.

Card transactions now return paymentAccountReference.
The PAR identifies the underlying account behind a card, so transactions made with
different tokens of the same card can be tied together. It is nullable — not
every transaction carries one.
Merchant onboarding is documented end to end, and the sandbox now mirrors
it. The reference walks the full sequence from company lookup to an
active merchant. The sandbox answers from a fixed set of companies per market that
behave like the real thing — including the failure cases — so you can
build the whole flow before touching production. The new
GET Sandbox/Merchant/sandbox-cases lists every company available to
you and what each endpoint answers for it.
The mTouch endpoints have been removed. They were never taken
into use, so no live integration is affected.

The full reference lists every endpoint, its parameters and its responses.
