 App Name is a mandatory field for many of the Pinterest Conversion API destination's mappings. Segment's mobile libraries automatically collect and map the App Name to the correct field. However, Segment's web or server-based libraries do not automatically collect this field, which can cause mappings to fail. Segment recommends adding the App Name to the Segment event, or hardcoding a static string in the mapping as the App Name.
