Pinterest Conversions API Implementation

Server-side conversion tracking for Pinterest Ads: how it works, dedupe with the browser tag, and how to verify it landed.

Quick answer

Pinterest's Conversions API sends conversion events from your server directly to Pinterest Ads, deduplicated against the browser-side Pinterest tag, recovering conversions a browser-only setup would lose.

What Pinterest Conversions API does

Pinterest's Conversions API sends conversion events from your server directly to Pinterest Ads, the same events your Pinterest tag tracks client-side - checkouts, sign-ups, and other defined actions. It addresses the same browser-side event loss every platform in this category has built a server-side path to solve.

How delivery works

A server-side call to Pinterest's Conversions API endpoint, carrying the event, matched customer parameters, and a shared event identifier with the corresponding browser-tag event for deduplication.

Consent handling and verification

Gate the server-side event on the same consent record the browser-side tag implementation respects, and verify delivery and match rate in Pinterest's own Events Manager, not assumed from your server's response code.

Frequently Asked Questions

What is the Pinterest Conversions API?

Pinterest's Conversions API is a server-to-server connection that sends conversion events from your server directly to Pinterest Ads, complementing the browser-based Pinterest tag - the same server-side conversion pattern standard across every major ad platform.

Does Pinterest CAPI need the browser-side Pinterest tag too?

Yes, run both, deduplicated with a shared event identifier, the same pattern recommended across every platform this practice implements.

How do I verify Pinterest CAPI is working?

In Pinterest Ads Manager, under Conversions -> Events Manager, check event delivery health and match rate for your Conversions API source, and use Pinterest's test event tool before relying on live traffic.
