I have a Google App Engine app which was created in early January 2013. I now want to use the Google Calendar API to post calendar entries from my GAE app and - after reading about the various options - I decided that Service Accounts with OAuth 2.0 authentication would be the best option. This approach requires the use of a private key to sign a JSON data structure with various credentials.
Now the Google documentation states:
During the creation of a service account, you will be prompted
to download a private key.
I checked my GAE dashboard and can see that there's a service account associated with it but I cannot remember ever being prompted to download a private key. I checked the Google Cloud Dashboard but could not find any links to obtaining such a key either.
Is it possible to obtain the required key at this moment and if so, how?
