Is there any Event that I can subscribe to that will tell me when the Tealium Site Catalyst Tag is ready? Since Tealium loads gpt.js, I want to subscribe as follows googletag.pubads().addEventListener('slotRenderEnded', handler);

Tealium Event for Tag Ready

[ty_gavin]

Steve, I may need a few more details to understand the use case. One idea is to use "Bundling" so that the SiteCatalyst tag is inside of utag.js. Then you are guaranteed it is ready before all other tags fire. You can enable Bundling in Publish Settings (top-right button after clicking Publish.) This requires that your SiteCatalyst tag is set to load on all pages (which is typical.) Also, don't forget to move the SiteCatalyst tag to the top of the list of tags. -Ty
