Use case

Webhooks for auth and lifecycle events

AscendKit emits configurable webhooks for auth and lifecycle events with event filtering, signature verification, and test delivery. Both the JS and Python SDKs verify signatures, so your backend can react to sign-ups, journey transitions, and survey responses securely.

How it works

  1. 1. Configure an endpoint
    Register a webhook endpoint in the portal and filter it to the events you care about.
  2. 2. Verify signatures
    Use the SDK signature verification in JS or Python to confirm each delivery is authentic.
  3. 3. Test delivery
    Send a test event from the portal to confirm your endpoint handles the payload before going live.

FAQ

Are webhook payloads signed?

Yes. Deliveries are signed and both SDKs include signature verification helpers so you can reject forged requests.

Can I filter which events I receive?

Yes. Endpoints support event filtering, so you only receive the auth and lifecycle events relevant to your integration.

Start with one API key

Auth, email, surveys, and journeys share one user record, so you ship this without stitching vendors together.
