The Problem & Solution
The Blind Spot in Digital Marketing
Without OCAPI
Consumers discover online, but buy in-store. Without a connection, digital ads get zero credit for offline sales.
- Algorithm learns only from web purchases.
- In-store sales driven by ads are invisible.
- True Return on Ad Spend (ROAS) is unknown.

Acts like a tracking pixel for your physical stores. It securely sends in-store purchase signals from your POS directly to Meta.
Accurate ROAS

The Architecture
How Data Flows Securely
Ad Interaction

In-Store Sale
Customer makes a physical purchase at your POS.
Secure API Sync
POS automatically sends data to Meta via OCAPI.
Attribution
Meta matches the sale and optimizes future delivery for both online & offline revenue.
Your Customer Events are
100% End-to-End Hashed.
We understand your absolute obligation to protect customer PII. With OCAPI, privacy isn’t an afterthought—it’s mathematically guaranteed.
Local SHA-256 Hashing
Customer details are irreversibly scrambled using the industry-standard SHA-256 algorithm locally on your server before any data is transmitted.
Meta Never Sees Raw Data
Meta only receives the hashed string. They compare it to their own hashed user database. If there’s no match, the hash is immediately discarded. They never learn the customer’s identity.
Global Privacy Compliance
This zero-knowledge architecture ensures you remain fully compliant with GDPR, CCPA, and DPDP laws while still unlocking advanced measurement.
