See more guidelines on setting up the Google tag.
If you installed the Google tag on your website from another Google product (example: Google Analytics) or from another Google Ads account, copy the 'config' command below and add it to every instance of the Google tag, right above the end tag.
gtag('config', 'AW-17770767687');
If you or a manager account already installed the Google tag on your website while setting up the tag for another conversion action, make sure that the tag is on every page of your website and check that the 'config' command has this Google Ads account's conversion ID: AW-17770767687
