Hi Eray,
Thank you for reaching out to us.
Can you further elaborate what campaign criterion that you're trying to update? You can see this sample code when updating the
Campaign Criterion Bid Modifier.
With regard to updating the ad title, you can first check on this
guide if the ad type that you're currently using is mutable. If yes, you can then check this
sample code for more details.
Regards,
