How do enable access to Google Analytics API for an Installed Application?

Question

I am writing a small program to retrieve and display Google Analytics information. I keep getting a 403 Forbidden error because of insufficient permissions.

I read on other posts that you have to add the email address associated with the client id you are using to access analytics in User Management.

The client id I am using however is associated with an installed application and doesn't have an email address, it only lists a client id, client secret, and redirect Urls as credentials in the developer's console.

How can I allow access for this client id when there is no associated email address listed in the developer's console to grant permissions to on the User Management page in Google Analytics?

Simply follow Google's OAuth 2.0 guide for installed applications.

1. Create a URL for authorization like you would for a web app. Only set redirect_uri to urn:ietf:wg:oauth:2.0:oob.
2. Point your user to this URL and let him authorize your app. Then the user will receive a code.
3. Prompt the user to enter this code in your app and use it to retrieve a refresh token from Google.
4. Store the refresh token and use it to get a fresh access token whenever you need one.
