Pinterest

Pinterest sits between discovery and intent, and performs for brands in home, apparel, beauty and anything with a strong visual consideration phase.

Its Conversions API accepts server-side events so that purchases completed days after the original save or click still get attributed.

Pinterest sits earlier in the consideration cycle than most paid channels: people save a pin and buy days or weeks later. Its Conversions API accepts server-side events with hashed email and phone plus a click identifier, so a purchase that completes long after the original session can still be attributed. Events sent through the API and events from the tag are deduplicated on a shared event ID.

Pinterest’s long consideration window is exactly where browser identifiers expire. Upstack resolves each conversion against a device graph whose matches persist for months rather than days, so a purchase that happens three weeks after the save is still attributable. Events are sent server-side and deduplicated against the tag.
