Integrating Macros in Your VAST

Incorporating macros into your VAST setup is straightforward:

Access your Viously platform settings here.
Add the desired macros directly to the VAST URL, for example:

https://pubads.g.doubleclick.net/gampad/ads?iu=/1234567890/external/single_ad_samples&sz=640x480&output=vast&unviewed_position_start=1&env=vp&gdpr=%%GDPR_APPLIES%%&gdpr_consent=%%GDPR_CONSENT%%&description_url=%%URL%%&correlator=%%CACHEBUSTER%%

For Google VAST, pass values using the cust_params feature for targeted Google Ad Manager integrations:

https://pubads.g.doubleclick.net/gampad/ads?iu=/1234567890/external/single_ad_samples&sz=640x480&output=vast&unviewed_position_start=1&env=vp&cust_params=player_width%3D%%PLAYER_WIDTH%%%26player_height%3D%%PLAYER_HEIGHT%%

Ensure URL encoding for the key values (= as %3D and & as %26).
