Who calls this public method? I couldn't find it in the current code base.

Can we use mojo instead? Then we don't need to add a bunch of payment structs to
public/ APIs.

I'm now mojofying IPCs related to dispatching events (but it's in
content/renderer): 
https://codereview.chromium.org/2490623005/diff/40001/content/common/service_...
I think this is fine for now though we need to move the codes from
content/renderer to blink later as a part of the onion soup.
