To weigh in here wearing my Worldpay hat, not my chairperson's hat, I would say that an non-browser API is important. 

It seems to me that the consensus was reached, from my chair perspective, simply as a reflection of work prioritisation and an indication of the mountain we have to climb. There is a lot of energy around the browser API and lots of people to do work. There are (it seems to me) fewer participants who are prepared to push ahead on the non-interactive API. I suppose that also reflects the observation (which is reflected in the original justification of the WG) that there is a lot of opportunity in improving the consistency of the user experience of payments in the web and so the obvious  place to fix that first is in interactive browser-based interactions.

Something that I would really like to see is more representation in the working group from the "creditor/payee/merchant" side of the equation. Hopefully the outreach activities in San Franscisco's F2F will help that.

> The charter doesn't call for a Note or an "understanding;"  it calls for a
> Recommendation.
> If there is disagreement that "Messages Recommendation" implies an HTTP
> API, then NOW is the time to call that out.  To me it's obvious, but I'm willing
> to be corrected.
> Second point, the Messages Recommendation comes before any other
> deliverables in the charter.
> I'm fine with the WG ordering it's work for efficient execution.  Order may

> out.
> Third point, what you designate as "non-interactive" scenarios includes
> almost all applications in "brick-and-mortar" or (the increasingly visible)
> hybrid use cases.
> Finally, web browser API are very helpful.  For functions (like GPS) that
> mainly talk to lower levels of a local system, relying on the browser from the
> API down is OK.  But for situations that are designed to connect stakeholders

> that make those messages easy to use.  But while NACS understands that
> browser APIs may be essential to make the HTTP API successful, not having
> the HTTP API leaves the most of the use cases we care about unaddressed.
> Summary, I think the charter is correct.  If I've messed up something, please
> let me know.
