What server-side does for your Pinterest campaigns
Tag + Conversions API in parallel
Pinterest deduplicates by event_id. Send both paths and you get 100 % coverage — the tag catches the fast interaction, server-side fills in the conversions the browser lost.
Enhanced Match + PII hashing
We hash email, phone, and external ID with SHA-256 exactly per Pinterest specs. Higher match rate = better attribution and campaign optimization.
epik click ID restore
Pinterest also attributes by the click ID from _epik. Our Click ID Restorer stores it in a first-party cookie and cache, so the conversion arrives with correct attribution even days later.
No per-pixel fee
Pinterest is one of 18 supported platforms in the plan from CZK 349. No per-pixel fees.

Frequently asked questions
Does this replace the Pinterest Tag? +
No — we recommend both. The tag catches on-site behavior; server-side via CAPI fills in the conversions the browser loses. Pinterest deduplicates by event_id.
What is Enhanced Match? +
Enhanced Match is hashed PII (email, phone) sent with the event. It raises the match rate — Pinterest matches more conversions to users and optimizes better.
Do you send standard and custom events? +
Yes — standard (PageVisit, AddToCart, Checkout, Signup…) and custom events with their own parameters and value.
Do you support Pinterest deduplication? +
Yes — we send the same event_id via the tag and the Conversions API; Pinterest matches them and doesn't double-count.
Pinterest attribution without pixel loss
The pixel loses conversions to ad-blockers and ITP. Server-side via DataNostro sends each one through the Conversions API with the right match rate. Five-minute setup, 14-day free trial.
