About Knock data sources

Knock data sources enable you to ingest event data from any tool to trigger messaging in a few clicks—no code required. Connect pre-built sources like Stripe, Clerk, Supabase, PostHog, and WorkOS, or map any custom webhook to workflows, audiences, and user updates in a few clicks. Knock handles verification, transformation, and action mapping so you can launch lifecycle and transactional messaging faster.
