This assumes you have already obtained a Bearer Token using the Venafi REST API. 

AVOID TROUBLE

In order to list credentials, you will need to have the security:manage scope when obtaining a Bearer Token using the Venafi REST API.

The following curl command can be used to return the credentials that have been created. In this example, the credentials created at \\VED\\Policy\\Credentials will be returned.

curl
--insecure
--request POST
--header "Authorization: Bearer abc123"
--header "Content-Type: application/json"
--data '{ "CredentialPath": "\\VED\\Policy\\Credentials" }'
--url https://tpp.example.com/vedsdk/Credentials/enumerate

Something like this should be returned. The details of a credential can be returned.

{
    "CredentialInfos": [
        {
            "ClassName": "Certificate Credential",
            "FullName": "foo"
        },
        {
            "ClassName": "CyberArk Password Credential",
            "FullName": "bar"
        },
        {
            "ClassName": "Password Credential",
            "FullName": "foobar"
        }
    ],
    "Result": 1
}
