Reminder: Change to contentBid setting in “Display Network Only” campaigns

As previously announced, we are removing the ability to set contentBid for “Display Network only” campaigns in the AdWords API on February 18th, 2014. Once this change happens, you will start receiving a ReadOnlyError.READ_ONLY error for all versions of the API if you set contentBid for a “Display Network only” campaign. You can use the fieldPath of the ApiError object to identify the operation triggering the error.

To make sure your applications and scripts work properly, you should make the following changes to your application code before February 18th, 2014:
  • modify your code to set the default ad group bid instead of contentBid for “Display Only Campaigns”
  • clear out the contentBid field for “Display Only Campaigns” so that AdWords will start using the default ad group bid when serving your ads
  • if you store campaigns in a local data store, re-sync your data store with AdWords to pick up the updated default bid values
If you have any questions about this change or the AdWords API in general, you can post them on our developer forum. You can also follow our Google+ page for updates about the AdWords API.
