How to get a Adwords API token without interaction with a user and browser

Question

My question is: How to get the token Adwords without needing to interact with the browser, but only via code

Now I run this code:

token = adwords.authorize () do | auth_url | 
  puts "Hit Auth error, please navigate to URL: \ n \ t% s"% auth_url 
  print 'log in and type the verification code:' 
  VERIFICATION_CODE = gets.chomp 
  VERIFICATION_CODE 
end 

And lap the token that is returned in browser url to liberate access.

Is to do all this using only Ruby code?

Thank you.

Answer 1

In order to get offline access to a user's AdWords data,

1. They must grant your app offline permissions
2. You must store and use a refresh token in order to get new access tokens after the initial one expires.

Asking for Offline Permissions

To ask for offline permissions, simply add the following query parameter to your OAuth2 URL:

&access_type=offline

Here is an example of a full URL requesting offline permission to the user's AdWords data:

https://accounts.google.com/o/oauth2/auth?access_type=offline&approval_prompt=auto&client_id=YOUR_CLIENT_ID&redirect_uri=YOUR_CALLBACK_URL&response_type=code&scope=https%3A%2F%2Fadwords.google.com%2Fapi%2Fadwords%2F

Your client ID will be something like this: 111122223333.apps.googleusercontent.com

Make sure to properly escape your callback URL before substituting it in.

Using a Refresh Token

This way, when you get an access_token for the account, you will also get a refresh_token from Google in the same response. Store this in your database with the rest of the account's data (including the access_token).

Later, when your original access token has expired, you can request a new one by making the following request:

https://accounts.google.com/o/oauth2/token?refresh_token=THE_REFRESH_TOKEN&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET&grant_type=refresh_token
