We recently announced that Bing Ads will end support for creating new and editing existing standard text ads (STAs) by July 31st, 2017. This platform change also applies to managing text ads via the Bulk API (Text Ad) and Campaign Management API (TextAd). Attempts to add new STAs or update STAs will return the CampaignServiceAdTypeInvalid error.
Your STAs will continue to serve after this date but, with the exception of the Status field, you will not be able to make any other changes to them.
Note: this announcement applies to both v10 and v11 of the Campaign Management and Bulk APIs.
As recommended in the announcement, you should replace your existing STAs with Expanded Text Ads (EXTAs) before July 31st. After your new EXTAs are created, you will still be able to retrieve and delete the STAs. For EXTA reference content, please see Expanded Text Ad (Bulk API) and ExpandedTextAd (Campaign Management API). More details on best practices around using EXTAs can be found in the previous announcement.
As always, if you have any questions about implementation please feel free to contact support or post in the Bing Ads API developer forum. Please also let us know your feedback at firstname.lastname@example.org.
