Endpoint Central (The token can be obtained in different ways see the API Manual)

Request post https://SERVER_EndpointCentral/api/1.4/desktop/authentication

        {
             "username":"USERNAME",
             "password":"PASSWORD IN BASE64",
             "auth_type":"ad_authentication" ,
             "domainName": "domain.local",
        }

Answer

{
    "message_type": "authentication",
    "message_response": {
        "authentication": {
            "two_factor_data": {
                "unique_userID": "USERNAME",
                "google_authenticator_key": "LELSY21KE3UREO",
                "is_TwoFactor_Enabled": true,
                "remember_token_days": 120,
                "OTP_Validation_Required": true
            }
        }
    },
    "message_version": "1.4",
    "status": "success"
}

We are interested in the parameter unique_user ID

Request post https://SERVER_EndpointCentral/api/1.4/desktop/authentication/otpValidate

{
 "uid":"HERE UID",
 "otp":"CODE OTP",
 "rememberme_enabled":"true"
}

In the answer we find device_token example '"device_token": "$2a$12$0j5b5.nhkiopiaa.tzlzlzesnov0omzr4oz7dotzhp5fos"

Post request with added device token https://SERVER_EndpointCentral/api/1.4/desktop/authentication

        {
             "username":"USER NAME",
             "password":"PASSWORD IN BASE64",
             "auth_type":"ad_authentication" ,
             "domainName": "domain.local",
             "device_token":"$2a$12$0J5W5Kovi.nhQuIOpIaa.tZlzLzEsnOv0OmzR4OZ7DoqjP5FoS"
        }

In the response, we find the auth_token parameter, this is our authorization token, the validity period is set to 120 days, following from "remember_token_days": 120

            "auth_data": {
                "auth_token": "E19A3E0-7F0C-4EEB-8E92-7C62D2FC2"
            }

osTicket

Opening include/staff/ticket-view.inc.php ~ 264 line after it we add

                <tr>
                    <th><?php echo __('PC'); ?>:</th>
                    <td><?php

                            }

                        }
                        //var_dump($result);
