Properly get existing GMB location extension feed when DistinctError.DUPLICATE_ELEMENT is thrown?

[Jon Perry]

I'm following this guide to set up GMB location extensions: https://developers.google.com/adwords/api/docs/guides/feed-services-locations#location_extensions_with_google_my_business

I'm unsure of how to obtain the id of the existing feed when the duplicate element exception is thrown.

What is the proper way to do this?

Some additional clarification would be greatly appreciated. Thank you.

More specifically, what are the criteria that determine the conflict? What can there only be one of? A feed with PlacesLocationsFeedData? One feed per GMB account? I can't find this information in the documentation.

Hi Jon, 

You need to use FeedService and FeedItemService to get the locations in your Location extensions feed. Could you send over the SOAP request and response logs for the request which encountered the DistinctError.DUPLICATE_ELEMENT error? You may get this error if you try to sync to a Google My Business account which is already added to your AdWords account. Meanwhile, I'll get in touch with the team to get the documents updated to provide more details on linking your Google My Business and AdWords accounts.

Thank you for your response.

What I'm unclear about is how to select the exact feed that is causing the error. What I'd like to do is attempt to create the feed and return its id and if I encounter the error I can instead find the feed that already exists and return its id. The problem being I'm unsure of the exact selection criteria I'm matching against to find the feed that already exists. Is it safe to assume that there will only be one SystemFeedGenerationData.Type == PlacesLocationFeedData and that is the feed I desire? Or are there other criteria that will throw DistinctError.DUPLICATE_ELEMENT?

Hi Jon, 

Only one GMB location extension feed is allowed per account. If you encounter the DistinctError.DUPLICATE_ELEMENT error when trying to create a location extension feed, you can use FeedService to get the existing Feed where SystemFeedGenerationData.Type is "PlacesLocationFeedData". Please see the updated Location extensions guide for more details.

Excellent. Thank you very much.
