FEED_ALREADY_EXISTS_FOR_PLACEHOLDER_TYPE after new site link for campaign

[Nikola Jordanovski]

Hello,

so i am trying to match site-links with my campaign feed:
1. I created a feed - saved it in database

2. Using that data am creating a new feedmaping

3. Now after that i want to create sitelinks for a campaign, after first using ADD "

$operation = new CampaignFeedOperation();
$operation->operand = $campaignFeed;
$operation->operator = 'ADD';

I have success with creating the site-link and matching it with the campaign.

But after that i get the error :
- FEED_ALREADY_EXISTS_FOR_PLACEHOLDER_TYPE -

I read somewhere about using SET instead of ADD but that deletes my current site-links and sets the new one.

My question is how to create new site links for a campaign even if i have sitelinks attached to the campaign?

Hi,

You can only have one CampaignFeed for a given campaign and placeholder type. If you want to add new sitelinks to your campaign then you should perform a SET operation where you pass the CampaignFeed with an updated matchingFunction that includes the feed item IDs for the existing sitelinks and the new sitelinks.

I would also recommend switching to the new extension setting services to manage your ad extensions. These services are much more straightforward than the feed services. For example, you won't have to work with matching functions -- the extension setting services will handle them for you.

Thank you for the help!
I will try with the new way of assigning ad-extensions!

Hi Josh , one question 

because the new way of adding site-links is not available right now i must keep using the Feed Services.

 1. Is there any example how to update the campaign matching function with the new feedItemId ,

    my logic tells me to retrieve current site feedItemIds associate with the wanted campaign and re-add them [ i know its wrong ] it should be easier like simple 

    retrieving current CampaignFeeds and just adding the new feedItemId to that function.
Anyway i am having huge problems understanding this part , how to retrieve current sitelinks - update - add - set...

Sorry for asking maybe my whole task on this question , but i have not other place to ask.

Thanks

Hi,

The new version (that includes the extension setting services) of each client library will be available within the next few days. I'd recommend waiting for that if you can. Otherwise, you'll have to interpret the matching function in order to add the additional feed item IDs, which will be considerably more difficult than using the new services.

Hi,
 Was thinking to migrated to extension setting services but it doesn't support location extension.
Currently our system are using Feed Service to manage adExtensions.
