What Is Pinterest CAPI?

Pinterest is a visual discovery and bookmarking platform where users can find, save, and share ideas and inspirations. It allows users to create and organize collections of images, known as "pins," into thematic boards. These pins can link back to the original source, making Pinterest a powerful tool for discovering new content, planning projects, and finding creative inspiration. The platform is widely used for ideas on fashion, recipes, home decor, and more, catering to both personal interests and professional marketing.

Pinterest Conversion API (CAPI) is a tool that helps businesses track user interactions on their websites more accurately by sending events directly from their servers to Pinterest. This API enables better measurement of conversion actions, such as purchases or sign-ups, without relying solely on browser-based tracking, which can be affected by ad blockers or cookie restrictions. By using CAPI, businesses can gain deeper insights into the performance of their Pinterest campaigns, improve ad targeting, and optimize their marketing strategies for better results.

What are the benefits of integrating MetaRouter with Pinterest CAPI?

Enhanced Data Accuracy: CAPI reduces the impact of ad blockers and cookie restrictions, ensuring more reliable tracking of user interactions and conversions.
Improved Data Security: Direct server-to-server communication provides a more secure way of transmitting data compared to browser-based methods.
Comprehensive Event Tracking: CAPI allows for tracking a wider range of user interactions and conversion events, offering deeper insights into campaign performance.
Better Ad Targeting and Optimization: With more accurate and complete data, businesses can refine their ad targeting and optimization strategies, leading to more effective marketing efforts.

Required & Recommended Identifiers

These identifiers must be mapped to Pinterest CAPI in order for successful user matching to occur. Without these IDs, any events sent to Pinterest CAPI may not be reflected within reporting. For your convenience, required and recommended IDs are mapped as Global parameters to ensure they are added to every event.
