Apple Pay on the web

Other than IndieGogo does any other web sites support it, like Amazon?

I'm not sure. I've yet to use Pay outside of an actual retail establishment. Hopefully, others who have will reply soon to answer your question.

It's amazing what information is available via a Google search.
Apple Pay - Where to Use - Apple
Scroll down to where is reads "Use Apple Pay on these apps and on these websites."
