Source IDs, sub-IDs and platform parameters

What you need to know

Optional VAST URL parameters can label where a commercial is being used so reported events can be attributed to a source or placement.

Step by step

1. Open Developer Tools and use the Advanced Tag Builder.
2. Choose a commercial or Ad Pod.
3. Enter a Source ID and optional Sub ID.
4. Select a platform and placement description.
5. Copy the generated URL and install it in your player.
6. Test the generated XML and verify reporting before relying on attribution.

Tips and common mistakes

• Parameters describe the request; they do not automatically schedule mid-roll ads.
• Use non-sensitive IDs; do not place personal data in ordinary tag parameters.
