AdGroupAdService operation limit.

[ADM]

Is there a limit on the number of operations that can be done with the
AdGroupAdService? I trying to change all the landing page URL for all
the ads in all the adGroups in a given campaign (happens to about
350-400 changes). I post the changes, apparently successfully, but
when I go to check the change history of that campaign I find that no
changes to any ads were ever made. Is this because there is a severe
lag in reporting this many changes, or because there is a limit on the
number of operations that can be done synchronously?

Hi,

It isn't possible to update the URLs of an ad, either in the AdWords
API or in the web interface. To change the destination URL you must
create a new ad with the new URL and then delete the old ad.

Does this still hold true?

Hi Shurti,

To clarify further, this is a result of how the product behaves.
