Once the Production Review of your integration review succeeds, fill out the Launch readiness questionnaire and submit it to Google. When Google receive the questionnaire response it will tell Google that you're ready to launch.

Additionally, fill out all required fields in the Contact Information tab in the Actions Center. These fields are mandatory before launch.

Once Google receives this information, Google will enable all of your entities in Production. This completes the integration and allows any external user to navigate to your entities' action_link through Google
