The Google AMP Client ID API provides you the ability to receive from Google an AMP Client ID for use in associating end user activities on your AMP and non-AMP pages with Google Analytics.

When you elect to integrate the Google AMP Client ID API with Google Analytics, you must provide clear notice (e.g., via a website Privacy Policy or via another common disclosure approach) about the use of the AMP Client ID in connection with Google Analytics. You must also comply with the EU User Consent Policy as applicable, including obtaining legally-valid rights for the transfer and use of the AMP Client ID in connection with your Google Analytics account.
