How do we add a custom-parameter/tracking-template on the Keyword level?
We're currently creating Final URLs for our Expanded Text Ads using "$expandedTextAd->finalUrls = $finalUrls;"
And an example shows how to add custom parameters on the Ad level:
$expandedTextAd->urlCustomParameters = new CustomParameters();
$expandedTextAd->urlCustomParameters->parameters = array($seasonParameter,
$promoCodeParameter);
But how do we add custom parameters at the Keyword level? There's an example
here, under "Create or edit custom parameters at the ad group or keyword level", which is what we need, but I'm not quite sure how to do it in our API script.
Thanks!
