Get the device's associated credential name via API

Hi,

In the Rest API documentation it's mentioned to use GetCredentialsForDevice endpoint to get associated credentials of a device, but in the response, I get all the credentials from different types exist in OPManager, and it's not possible to recognize the credential related to the device actually. here is a response example of http://localhost:8060/api/json/device/GetCredentialsForDevice :

{
"snmp": [
{
"credentialName": "Public",
"type": "SNMP v1/v2",
"checked": ""
},
{
"credentialName": "MyCredential",
"type": "SNMP v1/v2",
"checked": ""
},
{
"credentialName": "SNMP V3 Cred",
"type": "SNMP v3",
"checked": ""
}
],
"todisplayCitrix": "FALSE",
"toDisplay": "all",
"todisplayVMWare": "FALSE",
"todisplayUCS": "FALSE",
"cliCredentials": [
{
"credentialName": "Centos linux SSH",
"type": "Linux",
"checked": ""
}
],
"wmiCredentials": [
{
"credentialName": "testCred",
"type": "Windows",
"checked": ""
}
]
}

The same is for getAssociatedCredentials, Which lists all available credentials of snmp or WMI types and makes it impossible to detect the actual associated credentials with the device, ( http://localhost:8060/api/json/device/getAssociatedCredentials )
