# Handshake ## Handshake - [POST /v2/hooks/handshake](https://panorays-papi-v2-documentation.redocly.app/swagger/handshake/hookhandshakev2.md): Before being able to register and receive events, a server should be registered and verified. A “Verification Handshake” will happen which will verify SSL certificate and send a POST with a body of { challenge: } to the server given. The response to the POST message should contain the given challenge hash and status 200. The verification handshake process should only happen once and will be done during the onboarding of the API by Panorays.
