How do I update existing Ad Customizer feed items?

[Tacester]

Hi there,

I am new to the Adwords API and have so far found the examples in the client libraries very useful, however, I am stuck on figuring out how to update existing ad customizer feed items that I have already created.

I am using ad customizers to show product pricing in my ad copy. I am able to successfully create the feed and target the adgroups I want with no issue. Our product prices are subject to change weekly, however, I don't want to delete and recreate the feed every week as only a fraction of the entire product catalog prices may change.

Is there a way that I can get the existing feed items and which adgroup they are targeting, along with the current price string so that I can compare it to the latest product prices and then update the feed items where the product price has changed?

I am using the PHP client library and any help would be greatly appreciated :)

Hi, 

You can use FeedItemService to retrieve feedItems.
