You can connect without setting any connection properties for your user credentials. After setting the following, you are ready to connect:

InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.

DeveloperToken: Set this to the developer token of the AdWords account. You can get a developer token by signing up for the AdWords API. To do this, log in to the AdWords site with your MMC account and navigate to Settings -> Account Settings -> AdWords API Center. Apply for API access and wait for Google to contact you via email with more instructions. You should receive a token with a pending status. This token is only for testing and does not allow you to connect to live data. Google should contact you to fill out a questionnaire and once this has been received and approved by Google, you will receive your active developer token.

ClientCustomerId: Set this to the client customer Id of the AdWords account. You can find this value in your AdWords account. This value is not the same as the Id of the MCC account. You need to provide the lowest-level Ids to retrieve data.

When you connect the adapter opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The adapter then completes the OAuth process.
