This assumes you have installed the Hashicorp vault and that the vault is up and running, the vault has been unsealed, and that you have logged into the vault.

A GET request can be submitted to the /v1/auth/token/lookup-self endpoint to display the details of your token. For example, using cURL.

curl --header "X-Vault-Token: hvs.Qnh8giVRh2QP5eNsrGCrpLeT" --request GET --url http://vault.example.com:8200/v1/auth/token/lookup-self

Something like this should be returned.
