Overview
The LinkedIn Conversions API establishes a direct connection between advertisers' servers and LinkedIn, enabling them to measure the performance of their LinkedIn marketing campaigns, regardless of where conversions occur. This data can be used to optimize campaign performance. The Conversions API helps improve performance and reduce cost per operation by providing more complete attribution analysis, greater data reliability, and optimized delivery methods.

Conversion events can be traced back up to 180 days. Each conversion event has a 90-day retrospective period, and the conversion event must have occurred within the past 90 days to be attributable.
