I refer this page.
I had succeeded to get subscription list.
I fill 2 field "part", "channel Id(my channel Id)" and Authorize requests using Aouth 20.
Now, I want to get subscriptions feed.
I had tried to request, but it's error.
I fill follow field:
"part(snippet)", "channel Id" and set "mine" & "mySubscribers" to true
why can't success, error reason is "incompatibleParameters"
BTW, I try to fill "Id" field, but I really don't know what should I fill
it's annotation say "subscribe Id". What should I fill?
Update(06/19/2015):
I find solution,
in activity section, it response YouTube home page feed, but that's not sorted.
