Hi community, 

I am trying to work with the LinkedIn API to retrieve details about UGC posts (i.e. engagements, clicks, etc.). This information is not part of the LinkedIn Marketing Solutions CDATA connector, so I am using the CDATA provider for REST 2022. 

I first made a call to the posts API to ‘Find Posts by Account’: Posts API - LinkedIn | Microsoft Learn. After that I need to pass each Post ID into the Organizational Entity Share Statistics API to ‘Retrieve Statistics for Specific UGC Posts’: Organization Share Statistics - LinkedIn | Microsoft Learn. 

The problem I am facing is that the Posts API returns two types of posts (which cannot be filtered in the API): shares and UcgPosts. Each of those types of posts needs a different URL format in the ‘Organizational Share Statistics’ API. So, I need a way to only pass one type of post into the second API. UCG posts are posts where the ID starts with 'urn🇱🇮ugcPost:'

The file RSD 1.txt works, until the first ID from the Posts API is a UcgPost, instead of a share. The first Ucg post that gets passed into the second API returns the following error from the API: 

{"message":"Array parameter 'shares' value 'urn🇱🇮ugcPost:7071823186039828482' is invalid. Reason: Deserializing output 'urn🇱🇮ugcPost:7071823186039828482' failed","status":400}

So I tried to create a case statement in RSD 2.txt , but to no avail. It does not seem to be doing anything different: 

Does anyone have any experience with a filter or case statement between two tables in a nested API call like this? 

Kind regards,

Hi @andrew.gebhard 

You could change the setup of the file to be using a Query Slicer instead. There is a few posts about this and I mention it in the RSD guide.

Essentially you would then be able to create a Where clause that did the case statement or the query could be an or statement to select one or the other option.

SELECT * FROM LinkedInUGCPostStatistics WHERE IsUgc = true and ID IN (SELECT ID FROM Posts) OR IsUgc = false ID IN (Select ID From Posts)

 

Hi Thomas, 

I now have the following RSD files as attached and I have the following query table:

SELECT 
>organizationalEntity]
,  totalShareStatistics.clickCount]
,  totalShareStatistics.commentCount]
,  totalShareStatistics.engagement]
,  totalShareStatistics.impressionCount]
,  totalShareStatistics.likeCount]
,  totalShareStatistics.shareCount]
,  totalShareStatistics.uniqueImpressionsCount]
,  ugcPost] 
FROM  REST]..LinkedInUGCPostStatistics CDATA]

WHERE  ugcPost] IN (SELECT  id] FROM  REST]..PostIdList] where left(  id],15)= 'urn:li:ugcPost:' )

However, I get the error:

2023-06-12T14:44:43.910+02:00    0    The parameter ugcPost is required to be set for this operation.

 

See full error file attached. Am I missing a parameter in my RSD?

 

Kind regards,

Andrew

Hi @andrew.gebhard 

I know this has been a bit dead for a while, but I actually think I know why you get this error.

So if the result of the query after the where clause is not a (1,2,3,4,5) or similar kind of list you will need to set in a = instead. It can’t handle only one value it seems or you will get the error message you see.

SELECT 
 organizationalEntity]
, >totalShareStatistics.clickCount]
, >totalShareStatistics.commentCount]
, >totalShareStatistics.engagement]
, >totalShareStatistics.impressionCount]
, >totalShareStatistics.likeCount]
, >totalShareStatistics.shareCount]
, >totalShareStatistics.uniqueImpressionsCount]
, >ugcPost] 
FROM OREST].TLinkedInUGCPostStatistics CDATA]

WHERE RugcPost] = (SELECT Cid] FROM OREST].TPostIdList] where left( tid],15)= 'urn:li:ugcPost:' )

@andrew.gebhard please let us know if the answer above helps in resolving the issue you are experiencing
