A client in the retail space has a mobile app and a website where consumers can purchase goods. The client has been running a campaign for 12 weeks and wants to measure in-app conversions in Pinterest Ads Manager to get a full picture of the campaign. Which measurement solution should the media planner recommend?

The client needs to track in-app conversions, which the Pinterest API and a Mobile Measurement Partner (MMP) are designed to handle. The Pinterest API allows for server-to-server integration, enabling the client to send conversion data directly from their app backend to Pinterest. An MMP specializes in aggregating and attributing mobile app data, providing a comprehensive view of in-app actions across various ad platforms, including Pinterest. Both solutions provide the necessary functionality to measure in-app conversions accurately. The Pinterest tag is primarily for website tracking and cannot directly track in-app conversions. While the Conversions API (CAPI) is a server-to-server solution, Pinterest's specific implementation for app events is typically handled through their dedicated Pinterest API or by integrating with an MMP that then forwards the data.
