+### Hashicorp Vault secret(s)

+You can pull one or more Hashicorp Vault secrets into the trigger by defining the autentication metadata such as Vault `address` and the `authentication` method (token | kubernetes). If you choose kubernetes auth method you should provide `role` and `mount` as well.
+`credential` defines the Hashicorp Vault credentials depending on the authentication method, for kubernetes you should provide path to service account token (/var/run/secrets/kubernetes.io/serviceaccount/token) and for token auth method provide the token.

 ### Pod Authentication Providers
 
 Several service providers allow you to assign an identity to a pod. By using that identity, you can defer authentication to the pod & the service provider, rather than configuring secrets.
