问题
We have a public market place app which we can install from the Chrome webstore . The "Integrate With Google" button is visible in the webstore.
However when we try to put the same button in our website using
<g:additnow applicationid="APP-ID"></g:additnow>
We get a 403 Forbidden error from apis.google.com/additnow/additnow.html.
I have verified that our app is public, app id is correct, even listed out website url in the clien id javascript origins.

As noted in the documentation, after you publish your app to the store it may take a few days for the button to become active:
Note: After your app is published on Google App Marketplace, it may take a number of days before the Integrate with Google button can successfully install your app. Make sure to try it on a local page and make sure that it is working before placing the button on a live website.
The 403 error message indicates that it isn't active yet. Please try again in a couple of days.
