To make an authenticated request via the Vault HTTP API, which header would you use?

To make an authenticated request via the Vault HTTP API, you need to use the X-Vault-Token HTTP Header or the Authorization HTTP Header using the Bearer scheme. The token is a string that represents your identity and permissions in Vault. You can obtain a token by using an authentication method, such as userpass, approle, aws, etc. The token can also be a root token, which has unlimited access to Vault, or a wrapped token, which is a response-wrapping token that can be used to unwrap the actual token. The token must be sent with every request to Vault that requires authentication, except for the unauthenticated endpoints, such as sys/init, sys/seal-status, sys/unseal, etc. The token is used by Vault to verify your identity and enforce the policies that grant or deny access to various paths and operations. References: https://developer.hashicorp.com/vault/api-docs 3, https://developer.hashicorp.com/vault/docs/concepts/tokens 4, https://developer.hashicorp.com/vault/docs/concepts/auth 5
