Acquia currently supports two different Personalization modules. The instructions on this page are intended for subscriptions based in APJ and Europe regions.

For instructions intended for subscriptions based in the US region, see Acquia Personalization module (Limited Availability). If you are unsure of your subscription’s region, contact your account manager.


As you prepare to use Personalization with your website, ensure you plan for the following requirements:

Component Requirement

PHP Dependency manager** Composer (installation instructions)
Keys After purchasing Personalization, Acquia will email you a group of keys required to connect to the Personalization service.

Installing the Personalization modules

Use the following steps to install the Personalization client on your website:

  1. Open a command prompt window, and then navigate to the directory containing your main composer.json file.

    Note for Cloud Platform users

    The main composer.json file is located in your website’s docroot directory.

  2. Run the following commands:

    composer config repositories.drupal composer
    composer update
    composer require drupal/acquia_lift:~4.0
    cd .. && git add --all && git commit -a -m 'Adding Personalization modules' && git push origin master
  3. Deploy the updated master to your website on Cloud Platform.

  4. Sign in to your website as an administrator, and then click Extend in the administrative menu.

  5. Select the check boxes for the Personalization module.

  6. Click Install.

  7. In the administrative menu, click Configuration, and then click the Personalization link.

  8. Use the following steps to retrieve, and enter the information you need for the Personalization Credential section.

    1. Sign in to Personalization in a new browser tab, and then click the Configure tab.

    2. From the left menu, click the Customer Sites link.

    3. Click Add New Customer Site, specify the details for a new site, and save.


      Ensure that External ID is a machine-readable value.

    4. Go to the Personalize tab.

    5. From the left menu, click the Sites link and select the site that you just created.

    6. Retrieve the following values from the webpage:

      • Account ID
      • Site ID
      • Assets URL: For Personalization 4 users, use
      • Decision API URL
      • Authentication URL


      Each website must have a unique Site ID including development and testing environments. For more information, see per-environment configuration settings.

  9. Return to your website, and then update the values based on those from the Personalization interface.

  10. Click Save configuration.

Next, you must configure your per-environment configuration settings in your website’s settings.php file.

Per-environment configuration settings

Unless you specifically act, data collected by testing environments can contaminate data collected on your production environment.

To avoid data contamination, download this sample code, and install the code in your website’s settings.php file. Change the provided code to configure the variables associated with Personalization, and its components (including $config['acquia_lift.settings'], and $config['acquia_contenthub.admin_settings']) for different values depending on the environment in which they exist.

After you install all required modules, and ensure the modules are available for use, your production website can connect to the Personalization service. Your non-production website will not interfere with data collection for your production website.
