Hi everyone,
We would like to remind you that as previously announced, destination URL fields in AdWords will become read-only on July 1, 2015. Starting on that date, we will also begin upgrading your URLs (if eligible) to the new Upgraded URLs structure. As part of this change, we have marked all methods that set the destination URL of various entities as deprecated. These methods will generate a user error after July 1, 2015.
Before then, be sure to update your scripts code. Use the Upgraded URL fields instead of the destination URL field when creating entities such as ads, keywords, or sitelinks.
If you have any further questions about this change, let us know via our forum.
Cheers,
Anash P. Oommen,
AdWords Scripts Team.
