Verify/change application region at Google App Engine

Question

I\'m creating a GAE application.

When I set my GAE PHP application as an authorized application to access my Cloud SQL instance, I get the following warning:

Answer 1

You can get the AppId from the runtime environment:

Java:

ApiProxy.getCurrentEnvironment().getAppId()

or Python:

os.environ['APPLICATION_ID']

where the prefixes as mentioned by @Ilya and @Nikita still apply:

prefixed with e~ means EU and s~ means US.

P.S. It looks like both the dev consoles have been updated to get the App ID from elsewhere, so they don't have this prefix.
