Questions your team will ask.
What data does Snap need?
Event data plus hashed identifiers such as email, phone, and IP with user agent. The more matching parameters each event carries, the higher the match rate; Datahash hashes everything client-side or server-side before it reaches Snap. We start with a Pixel and event map audit, then close any gaps in match parameter coverage before configuring server-side delivery.
How is CAPI deduped against the Snap Pixel?
Both the Pixel and the server event carry the same event identifier, so Snap keeps one copy when the two arrive together. We verify dedupe in Snap Events Manager before turning campaigns over to the new setup, checking that Pixel coverage and the event map line up first. That prevents double counting on key events like purchase and checkout start.
Which events matter most?
Purchase, checkout start, add to cart, and sign-up carry the most optimization weight. We prioritize full-fidelity delivery of your lower-funnel events first, then extend coverage upstream. Each of these events is deduped against the Pixel and carries hashed first-party identifiers, giving Snap's optimization a clean signal on the events that drive your ROAS.
