The ugcPosts endpoint can be used to request a list of a posts that an organization has recently created using the following url template
https://api.linkedin.com/v2/ugcPosts?q=authors&authors=List(urn%3Ali%3Aorganization%3A{org_id})&count=100&projection=(paging,elements*,elements(*(id~)))
The results include both shares and ugcPosts, while the shares-endpoint includes just the shares. Every share has an activity-URN, while this is missing for ugcPosts. There seems to be no way to resolve the ugcPost-URN to an activity-URN, which means a permalink can't be generated.
Does anyone have a solution for this issue?
