Klaviyo Source Signals That Marketers Can Actually Use

Receive Klaviyo email, SMS, consent, and review events as signed inbound source signals for attribution and routing.

Klaviyo becomes an inbound source for campaign, customer, consent, and lifecycle activity. EVENTS Gateway verifies the webhook, normalizes the payload, and connects those signals to the same event layer used for attribution and destinations.

Marketer Gain

What marketers gain from Klaviyo

Marketers can connect Klaviyo lifecycle movement to acquisition, retargeting, and Shopify revenue signals without keeping Klaviyo isolated.

Technical Model

How the Klaviyo source integration works technically

Klaviyo sends webhook payloads into EVENTS Gateway. The request is protected with Klaviyo HMAC headers and an optional webhook ID check, converted into canonical event names, attached to identity and campaign context when available, and stored as a source event that can inform routing and reporting.

Provider Webhook

Klaviyo posts events such as event:klaviyo.clicked_email, event:klaviyo.opened_email, event:klaviyo.clicked_sms to a dedicated EVENTS Gateway URL.

Verification Layer

EVENTS Gateway validates the request using Klaviyo HMAC headers and an optional webhook ID check, then rejects malformed or untrusted payloads before they reach the shared event model.

Canonical Source Event

The raw provider payload is normalized into a reusable source event with contact, campaign, message, and click context where the provider sends it.

Marketing Context

Marketers can connect email, SMS, consent, and automation activity to site behavior instead of reading provider dashboards in isolation.

Why It Matters

Why Klaviyo belongs in the same event layer as your destinations

Lifecycle tools create valuable customer signals, but marketers lose value when those signals stay trapped inside one provider. EVENTS Gateway makes them usable across attribution, identity, routing, and reporting.
