What it does
Klaviyo upserts profiles, tracks events, and subscribes profiles to lists via the JSON:API endpoints.
Setup
- In Klaviyo → Account → Settings → API Keys, create a Private API Key (
pk_...) with Profiles / Events / Lists scopes. - In FlowFn, go to Platform Tools → Klaviyo → Connect and paste it as api_key.
Actions
- Upsert Profile, Track Event, Subscribe Profile to List
Notes
Klaviyo's JSON:API requires a revision header (pinned to 2024-10-15). Subscribe-to-list is async (returns 202).
