HI Nat

Sorry, slight confusion - this information is not from myself but from one
of the members of the ERPB PIS group - but I still think this is positive
movement as it provides a way for the industry to move beyond screen
scraping.
The conversations are not yet in the public domain, so I don't think I can
provide any more details at this point.

Ths issue that concerns me is the line that is being taken about redirect
based APIs.
CIBA is good as it allows "decoupled" flows and doesn't count as
redirection, BUT even with decoupled flows many are arguing for
"pass-through" or "embedded" flows as well - where the banking credentials
are entered into a third party site and then "passed through" to the bank
via API.

Unfortunately, the text of PSD2 supports their argument:

The payment initiation service provider shall:
> (a) not hold at any time the payer’s funds in connection with the
> provision of the payment initiation service;
> (b) ensure that the personalised security credentials of the payment
> service user are not, with the exception of the user and the issuer of the
> personalised security credentials, accessible to other parties and that *they
> are transmitted by the payment initiation service provider through safe and
> efficient channels*;


PSD2 Article 66.3

I think we can make an argument that any method that involves banking
credentials being entered on a third party site will severely reduce the
"Strong Customer Authentication" methods available for that bank to use.
