Upgraded URL, invalid char

[Hudarsono Hu]

Hi There,

We are testing out upgraded url, but it happened that it doesnt allow some characters, in this case an underscore.

We got error saying :  UrlError.INVALID_CHARACTERS_IN_URL_CUSTOM_PARAMETER_KEY

The problem is that, we wanted the click to be identified in google analytics, so in the url custom parameters, we use key such as utm_medium, utm_source, utm_term, which contain underscore. 

How are we supposed to do that with this upgraded url?

Thanks

Cheers

Hello,

Your utm_x parameters should not be specified as CustomerParameters. CustomParameters should only be used for parameters whose values are set by the AdWords user.

Luckily, you can use those parameters as a part of trackingUrlTemplate (if you use a tracking template) or finalUrls (if you don't use a tracking template). AdWords will automatically replace those parameters with the appropriate values.
