- User is deleted
- Repository is activated
- Repository is de-activated
- Build is created
- Build is updated or completed
Create a shared secret used to sign the http request. This shared secret is to be provided to both the Drone server and your webhook receiver.
$ openssl rand -hex 16 bea26a2221fd8090ea38720fc445eca6
