How does the Pinterest Conversions API complement the Pinterest Tag?

The Pinterest Conversions API complements the Pinterest Tag by providing a more robust and reliable method for tracking conversions. While the Pinterest Tag relies on browser-side tracking (cookies), the Conversions API allows advertisers to send real-time conversion data directly from their servers to Pinterest. This server-side tracking reduces reliance on cookies, which are increasingly impacted by privacy regulations and browser limitations, thereby mitigating signal loss and improving data accuracy. This ensures a more complete and accurate understanding of campaign performance, especially as cookie-based tracking becomes less effective. The API does not exclusively handle mobile users, require manual uploads, or continuously store cookies from all users; these are incorrect descriptions of its function.
