How do I use Hashicorp Vault in Cloud Foundry

Question

So I have a nodejs webservice which I push into Cloud Foundry (PCF), then I am storing some credentials in Vault so when a user hits my web service endpoint with some credentials I extract the credentials from the Vault, compare them against the credentials from the request and if the match I allow the request to be processed else I reject the request.

So to install Vault in PCF I use the next command:

cf create-service hashicorp-vault shared foo-vault

Then I create a key using this command:

create-service-key foo-vault foo-vault-key

Then I bind the service to the app like this:

cf bind-service foo-ws foo-vault

I restage the web service and when I print the environmental variables using this command:

cf restage foo-ws

I get this values:

{
    "hashicorp-vault": [{
        "credentials": {
            "address": "http://somehost:433/",
            "auth": {
                "accessor": "kMr3iCSlekSN2d1vpPjbjzUk",
                "token": "some token"
            },
            "backends": {
                "generic": [
                    "cf/7f1a12a9-4a52-4151-bc96-874380d30182/secret",
                    "cf/c4073566-baee-48ae-88e9-7c7c7e0118eb/secret"
                ],
                "transit": [
                    "cf/7f1a12a9-4a52-4151-bc96-874380d30182/transit",
                    "cf/c4073566-baee-48ae-88e9-7c7c7e0118eb/transit"
                ]
            },
            "backends_shared": {
                "organization": "cf/8d4b992f-cca3-4876-94e0-e49170eafb67/secret",
                "space": "cf/bdace353-e813-4efb-8122-58b9bd98e3ab/secret"
            }
        },
        "label": "hashicorp-vault",
        "name": "my-vault",
        "plan": "shared",
        "provider": null,
        "syslog_drain_url": null,
        "tags": [],
        "volume_mounts": []
    }]
}

So my question is if there is a way to define the backends, token and address?

Thanks in advance for your help.
