If I call `/v2/Authenticate/Tokens` with valid credentials but pass in an invalid value for `Tenant` or `Environment` or `Lifecycle`, how does the platform respond to those invalid inputs?

I assume you are talking purely about `/v2/Authenticate/Tokens`, not with the additional query params `?login` or `?refresh`as the behavior is different.  
If you have an invalid Tenant, Environment or Lifecycle you will get the following responses respectively with a 401 code:

```auto
{
    "ErrorMessages": [
        {
            "ErrorType": "Error",
            "ErrorSubType": "nwsysauthenticationexception",
            "ErrorCode": "TOKEN_REFRESH_FAILED",
            "ErrorDescription": "Token refresh failed. Caused by: Invalid tenant for user: <tenant name>",
            "ErrorStyle": null,
            "ErrorPayload": [],
            "ErrorTechnicalDetails": null,
            "ErrorDetails": {

            },
            "ErrorFields": [
                {}
            ]
        }
    ]
}

```

```auto
{
    "ErrorMessages": [
        {
            "ErrorType": "Error",
            "ErrorSubType": "nwsysauthenticationexception",
            "ErrorCode": "TOKEN_REFRESH_FAILED",
            "ErrorDescription": "Token refresh failed. Caused by: The environment <environment name> is invalid for the tenant <user tenant>.",

            "ErrorFields": [
                {}
            ]
        }
    ]
}

```

```auto

    "ErrorMessages": [
        {
            "ErrorType": "Error",

            ]
        }
    ]
}
