[Chris]

Converting several of our tracking templates to use https but not having any luck with the new AdService.mutate().

POST /api/adwords/cm/v201806/AdService

    <mutate xmlns="https://adwords.google.com/api/adwords/cm/v201806">

      <operations>

        <operator>SET</operator>

        <operand xsi:type="TextAd">

          <id>REDACTED</id>

          <trackingUrlTemplate>https://....REDACTED</trackingUrlTemplate>

        </operand>

      </operations>

    </mutate>

Getting this error, please help?  What am I missing?

Hi Chris,

Could you confirm if the Id that you are passing indeed belongs to a TextAd object? So I can further investigate, could you provide to me your clientCustomerId and the ad Id? You may reply to me via the Reply privately to author option.

Thanks and regards,

Peter

Thanks Peter, I sent you a private reply with all the info.

Hi Chris,

Thank you for sending the information I requested. However, after further checking on our end, it appears that TextAds are not included in the supported ad types that can be passed to the AdService.mutate() method. For more information, you can refer here for the supported ad types.

I hope this helps.
