Not sure why the Chrome Web Store dashboard fails to provide the oauth
secret- could it be that oauth 2.0 does not need one? I signed up
with another account and got the same result- secret was blank.
Regardless, the posted tutorials did not work as described,
(
https://developers.google.com/chrome/web-store/docs/get_started )
(
https://developers.google.com/chrome/web-store/docs/samples#php )
and kept giving us a 401 invalid credentials...
but it did mention other ways to generate the needed oauth token
including the oauth playground from google.
I used auth playground and put in the token info and secret from
there, along with the app id generated by chrome web store.
I then simply needed to open the link which was only available to test
publishers, and buy our own app!
