I am working on sending notification from gmail to webserver through pub/sub,

I have gone through documentation in that they have mentioned to enable the scopes 

https://cloud.google.com/pubsub/configure

I am specifying the following scopes through code

https://www.googleapis.com/auth/cloud-platform,
https://www.googleapis.com/auth/pubsub

Even though after specifying these scopes after calling watch() for the particular user its giving me 

Google::Apis::ClientError: forbidden: Error sending test message to Cloud PubSub projects/project-id/topics/topic-name : User not authorized to perform this action.

So do I need to enable these scopes from google console ? If yes then can you please tell us the directions for doing it.

  • @GaganGami thanks for the link however it doesn't mention anything related to scope, which I am looking for. – Rahul Feb 19 '16 at 12:33

Scope is not relevant here. Gmail system always uses this service account "gmail-api-push@system.gserviceaccount.com". What you need to do is to give this service account a permission for publishing messages on your topic.
