Prerequisites

Before starting this integration, you need:

Your MomentScience JS SDK snippet (found in the dashboard under Integration)

Access to your Google Ad Manager account with creative creation permissions

Knowledge of where you want to display MomentScience units on your website

Integration Steps

Step 1: Create a new creative in Google Ad Manager

Navigate to Delivery > Creatives

Under Display Creatives, click New Creative

Select your advertiser from the dropdown menu

Choose Third party as the creative type

Step 2: Configure the creative settings

Enter a descriptive name for your creative

Example: MomentScience - Banner - 1x1 - Homepage

Set the Target ad unit size to 1x1

This size provides universal compatibility across placements

Select Standard for the Code type

Uncheck serving into a SafeFrame

For additional details on setting up third-party creatives in Google Ad Manager, refer to the official Google Ad Manager support documentation.

Step 3: Test your implementation

Use Google Ad Manager's Preview tool to test your creative

Navigate to the page where the creative should display

Verify that MomentScience content appears correctly

Check the MomentScience dashboard to confirm impressions are being recorded

Advanced: Passing payload data

Enhance targeting by passing user data to MomentScience through the payload object. There are two methods to pass payload data when using Google Ad Manager:

Method 1: Set payload values before loading MomentScience

Add this code to your page before the GAM ad tag loads:

// Set a single payload value
window.AdpxUser = Object.assign(window.AdpxUser || {}, { 
  "email": "[email protected]" 
});

// Or set multiple values at once
window.AdpxUser = Object.assign(window.AdpxUser || {}, {
  "email": "[email protected]",
  "firstname": "John",
  "lastname": "Doe",
  "amount": "99.95",
  "currency": "USD"
});

Method 2: Set payload values after MomentScience loads

Modify your creative code in GAM to prevent auto-loading by setting autoLoad: false

Add this code to your page where you want to set the payload and display the content:

// Set payload values
window.AdpxUser = {
  "email": "[email protected]",
  "firstname": "John",
  "lastname": "Doe"
};

// Refresh the MomentScience unit to display with new payload
window.Adpx.refresh();

When you set a payload attribute, it overwrites any existing value for that attribute. For example, if customAttribute is set to 'someValue' and later set to 'newValue', the final value will be 'newValue'.

Verification and troubleshooting
