是的，票证可以通过 GUI 链接到 configItem，并且可以通过 Web 服务完成。
首先，您应该编写一个新的通用接口连接器操作，它将处理方法LinkAdd from 链接对象班级 （APIdoc https://github.com/OTRS/otrs/blob/1e908159a5dbdcfb94cc35d13bf15b04ac3e6a24/Kernel/System/LinkObject.pm )
然后通过新的 XML 文件创建并注册新操作，如下所示：
文件名：GenericInterfaceLinkObjectConnector.xml
<?xml version="1.0" encoding="utf-8"?>
<otrs_config version="1.0" init="Application">
<ConfigItem Name="GenericInterface::Operation::Module###LinkObject::LinkAdd" Required="0" Valid="1">
<Description Translatable="1">GenericInterface module registration for the operation layer.</Description>
<Group>GenericInterface</Group>
<SubGroup>GenericInterface::Operation::ModuleRegistration</SubGroup>
<Setting>
<Hash>
<Item Key="Name">LinkAdd</Item>
<Item Key="Controller">LinkObject</Item>
<Item Key="ConfigDialog">AdminGenericInterfaceOperationDefault</Item>
</Hash>
</Setting>
</ConfigItem>
</otrs_config>
之后，您可以从 OTRS GUI 发布新的提供程序 WebService，其中使用新创建的连接器。
确保传递该方法所需的所有参数！
$True = $LinkObject->LinkAdd(
SourceObject => 'Ticket',
SourceKey => '321',
TargetObject => 'FAQ',
TargetKey => '5',
Type => 'ParentChild',
State => 'Valid',
UserID => 1,
);
UPDATE:
请阅读这个Document https://otrs.github.io/doc/manual/admin/3.2/en/html/genericinterface.html要了解通用接口是如何构建的，然后请添加一个新的连接器（ LinkObject ）
要注册连接器及其操作 - 将 XML 文件放入 /Kernel/Config/Files/...
然后转到 Sysconfig -> GenericInterface -> GenericInterface::Operation::ModuleRegistration 并在 GenericInterface::Operation::Module###LinkObject::LinkAdd 旁边设置一个勾号并保存更改
然后将此连接器文件添加到 /Custom/Kernel/GenericInterface/Operation/LinkObject/LinkAdd.pm

然后它应该出现并可以从管理 -> Web 服务 -> 可用操作下拉列表中使用，当然也可以用作 Web 服务。
PHP 使用示例如下：
#### Initialize new client session ####
$client = new SoapClient(
null,
array(
'location' => $url,
'uri' => "Core",
'trace' => 1,
'login' => $username,
'password' => $password,
'style' => SOAP_RPC,
'use' => SOAP_ENCODED
)
);
#### Create and send the SOAP Function Call ####
$success = $client->__soapCall("Dispatch",
array($username, $password,
"LinkObject", "LinkAdd",
"SourceObject", 'Ticket',
"SourceKey", $ticket_id1,
"TargetObject", 'Ticket',
"TargetKey", $ticket_id2,
"Type", 'ParentChild',
"State", 'Valid',
"UserID", '1'
));
如果出现错误 - 启用调试、查看系统日志并检查 OTRS 的所有初始设置
祝你好运！
更新#2
要注册 Web 服务 - 按添加新 Web 服务按钮，根据需要命名并设置以下设置（选择 LinkAdd 操作）并保存
更新#3
这是 OTRS 5 的更新模块文件
