One server-side Conversions API for every ad platform.
Browser pixels miss conversions, double-count the ones they catch, and starve the ad platforms of the revenue signal they need. Signal Sparrow sends accurate, deduplicated, revenue-backed conversions server-side to Meta, Google, TikTok and more — so match quality goes up and CPA comes down.
Send conversions from your server, not the browser.
A Conversions API (CAPI) sends conversion events to an ad platform directly from your server, instead of relying on a pixel that fires in the visitor's browser. Because the event originates server-side, it isn't lost to ad blockers, iOS restrictions or dropped tabs — and you control exactly what data is sent and how it's matched.
Signal Sparrow builds on your first-party tracking to generate one clean, deduplicated conversion stream, then forwards it to every platform's API with hashed identity — no separate pixel setup per channel, no duplicate events, no guesswork.
Server-side delivery
Sent from our servers, not the browser — unaffected by blockers or iOS.
Deduplicated
One event, matched by event_id. Pixel and server fire together without inflation.
Revenue-backed
Real Stripe MRR, not a $0 pixel fire. Platforms bid toward paying customers.
PII hashed
SHA-256 before it leaves your workspace. You stay the data controller.
Your ad platforms are optimizing on half the data.
Pixel-only conversion tracking loses signal, sends noisy events, and can't see revenue. That means the algorithm bids on the wrong outcomes — and you pay for it in CPA.
Signal loss
iOS ATT, Safari/Firefox ITP, consent banners and ad blockers drop an estimated 10–30% of conversions before the pixel fires. The platform never learns which clicks converted.
Duplicate & noisy events
Running a pixel and an API without deduplication double-counts conversions, inflating reported ROAS and corrupting the optimization signal.
No revenue context
A browser pixel sees a $0 trial start, not the $149/mo subscription that lands in Stripe a week later — so platforms optimize for cheap signups, not paying customers.
Capture once, deduplicate, forward everywhere.
- 01
Capture first-party events
A cookieless, first-party snippet records every click and conversion from your own domain — the accurate signal browser pixels lose.
- 02
Deduplicate and enrich
We assign a stable event_id, join the event to its Stripe revenue and hashed identity, and reconcile it to your MRR so the payload is clean and complete.
- 03
Forward server-side
The enriched conversion is sent to each platform's Conversions API with retries and delivery monitoring — so nothing is silently dropped.
The same conversion, two very different signals.
A browser pixel and a server-side Conversions API can report the same purchase — but only one survives blockers, dedupes cleanly, and carries the revenue that teaches the algorithm to find more paying customers.
Higher event match quality, lower cost per acquisition.
Illustrative figures based on typical results when server-side CAPI replaces pixel-only conversion tracking.
Only send conversions you can prove.
More events are only better if they're real. Every conversion Signal Sparrow forwards is reconciled to Stripe first: attributed revenue plus direct/unknown equals your net MRR for the period, to the cent. We never inflate the signal to look good in a dashboard — the numbers you send to Meta and Google are the numbers in your bank account.
Forward revenue-backed conversions anywhere.
Set up your conversion pipeline once and send to every major ad platform's API — per-event mapping, automatic retries and health monitoring included. No separate integration project per channel.

A server-side Conversions API (CAPI) sends conversion events to an ad platform directly from your server rather than from a pixel in the visitor's browser. Because the event doesn't depend on the browser, it isn't lost to ad blockers or iOS restrictions, and you control the data and matching — which raises event match quality and lowers CPA.
A pixel fires client-side and is subject to blockers, ITP cookie limits and consent gating. A Conversions API call is made server-side, so it delivers reliably. Used together with proper deduplication, CAPI fills the gaps the pixel misses without double-counting.
No. Signal Sparrow assigns a stable event_id to every event so platforms like Meta deduplicate the pixel and server events automatically. You get the coverage of both without inflating your conversion counts.
Meta Conversions API, Google Ads, Google Analytics 4, TikTok Events API, and LinkedIn Conversions API — all from one pipeline, with per-event mapping, retries and delivery monitoring.
We send hashed first-party identifiers and real Stripe revenue with each conversion, giving platforms stronger matching signals and a revenue-based optimization target. Better match quality plus a paying-customer target means the algorithm bids toward revenue, not cheap trials.
Yes. You remain the data controller, all PII is SHA-256 hashed before it's forwarded, consent state is respected, and data can be stored with EU residency under a GDPR-ready DPA.
