Pinterest Conversions API,
delivered server-side.
Pinterest is the visual discovery platform — shopping pins, catalog ads, and a high-intent audience browsing for products they want to buy. But Pinterest's user base skews heavily toward Safari and iOS, where Intelligent Tracking Prevention and ad blockers are most aggressive. The Pinterest Tag loses pin-click conversions in exactly the moments that matter most for e-commerce.
Ingest Labs sends your events to the Pinterest Conversions API server-side — enriched with first-party identity for better audience matching, deduplicated against your Tag, and filtered by user consent. Your attribution stays complete, your audiences build on real data, and Pinterest's algorithm optimizes on every conversion.
Why Pinterest + Ingest Labs
Pinterest has an outsized Safari problem. The platform's audience — predominantly female, predominantly mobile, predominantly iOS — browses on the browser that is most hostile to ad tracking. Safari's ITP caps first-party cookies at 7 days and blocks third-party cookies entirely. Add ad blockers to the mix, and the Pinterest Tag can miss 20–40% of conversion events on a typical e-commerce site.
The Conversions API solves this by sending events server-side, where browser restrictions don't apply. It accepts hashed email, external IDs, and click IDs — identifiers that let Pinterest match conversions to users with far more confidence than cookie-based tracking. The result is more accurate attribution, better custom and lookalike audiences, and a smarter optimization algorithm that sees the full picture.
Ingest Labs makes the integration seamless. One install captures purchase, add-to-cart, and checkout events from your site, enriches them with first-party identity, hashes PII to Pinterest's spec, deduplicates against your browser Tag via event_id — and delivers everything to Pinterest's CAPI in real time. Your campaigns optimize on complete data, and your audiences reflect real customer behavior.

Frequently Asked Questions
What is Pinterest Conversions API?
Pinterest Conversions API is a server-to-server integration that sends conversion events directly from your server to Pinterest — bypassing ad blockers, Safari ITP, and browser cookie limitations. Ingest Labs manages the full CAPI pipeline, including event deduplication with your existing Pinterest Tag.
Will running CAPI double-count my conversions?
No. Ingest Labs attaches a unique event_id to every browser and server event. Pinterest deduplicates them on ingestion, so you see one conversion per action in Pinterest Ads Manager — never two.
Do I still need the Pinterest Tag if I'm using CAPI?
Pinterest recommends running both in parallel. The Tag captures in-browser signals and supports features like automatic enhanced matching. CAPI fills the gaps where browsers fail. Together they deliver a complete, deduplicated view of your campaign performance.
How does this improve audience building on Pinterest?
Server-side events include richer first-party data — hashed email, external ID, and click ID — that the Pinterest Tag often can't capture due to browser restrictions. This enriched data helps Pinterest build more accurate custom and lookalike audiences, improving both targeting precision and campaign performance.
Is this GDPR and CCPA compliant?
Yes. Ingest Labs integrates with your consent management platform (OneTrust, Cookiebot, Consentmo, or custom) and only forwards events to Pinterest when the user has granted marketing consent. Every consent decision is logged for audit, and PII is hashed before transmission.
How long does setup take?
Most customers are live on Pinterest CAPI in under 24 hours. Shopify stores install the Ingest Labs app and connect their Pinterest ad account in minutes. Custom sites use our SDK plus server-side tag manager for streamlined setup.
