Vault api kv get : field parameter not working

we are trying to get the specific field from the secret via a vault API call.

curl -v -k --header "X-Vault-Token: " --request GET https:///v1/<secretengine_name>/?field=

The above API call is not working. It’s working with CLI.

Thanks,
Niranjan

Is this the k/v secret engine and if so, is it the versioned on?

If this is the case there should be an additional data between secret-engine and your-key.

Even with K/V2 how to retrieve the specific key from the secret. If the secret has multiple key/vaule pairs.
