The brand
Eyewa is the Middle East’s largest online eyewear retailer, selling glasses, sunglasses, and contact lenses through a fast growing mobile app alongside its web store.
The problem
App conversions were the hardest signal to get into Snap reliably. SDK-only measurement after iOS privacy changes left gaps in purchase reporting, so Snap campaigns driving app revenue looked weaker than they were and optimization had less to learn from.
What Datahash did
Datahash implemented Snap App Conversions API on Signals, routing in-app purchase and funnel events server-side with hashed identifiers and deduplication against SDK-reported events. The Eyewa team went live without an app release and without pulling engineers off the product roadmap.
Results
Within two weeks of going live on Snap App CAPI, Eyewa measured a 68% increase in return on investment. Complete app purchase signal gave Snap’s models what they needed to find high-value buyers, and gave the marketing team numbers they could plan against.
