Dynamics crm Dynamics 365 Web API-如何使用Web API注册webhook的步骤？

我正在探索Dynamics CRM web API，并尝试注册一个webhook，当实体（如联系人/帐户）更新/创建时将触发该webhook。我可以使用PluginRegistration工具创建此设置，但我想从我的工作流中排除此工具。如果可能的话，我想注册webhook和step-through web API。我能够成功注册webhook-使用对以下端点的POST请求：

/api/data/v9.0/serviceendpoints

与以下机构合作：

{
    "name":"Test Webhook",
    "url":"http://somewebhookendpoint.somedomain.com",
    "contract":8,
    "authtype":4,
    "authvalue":"args"
}

但是，当尝试创建

sdkmessageprocessingstep

（我假设这是我在这个webhook下尝试创建的步骤）时，我收到了

400个错误请求。这是我正在传递给sdkmessageprocessingstep创建端点的请求正文
（api/data/v9.0/sdkmessageprocessingsteps）

但是在传递这个请求时，我得到了以下错误（这似乎表明我没有以正确的格式发送
sdkmessageid
）

但是没有用（删除@也不起作用）。响应似乎指定我传递了一些不正确的参数：

{
    "error": {
        "code": "0x0",
        "message": "An error occurred while validating input parameters: Microsoft.OData.ODataException: Does not support untyped value in non-open type.\r\n   at System.Web.OData.Formatter.Deserialization.DeserializationHelpers.ApplyProperty(ODataProperty property, IEdmStructuredTypeReference resourceType, Object resource, ODataDeserializerProvider deserializerProvider, ODataDeserializerContext readContext)\r\n   at System.Web.OData.Formatter.Deserialization.ODataResourceDeserializer.ApplyStructuralProperties(Object resource, ODataResourceWrapper resourceWrapper, IEdmStructuredTypeReference structuredType, ODataDeserializerContext readContext)\r\n   at Microsoft.Crm.Extensibility.CrmODataEntityDeserializer.ApplyStructuralProperties(Object resource, ODataResourceWrapper resourceWrapper, IEdmStructuredTypeReference structuredType, ODataDeserializerContext readContext)\r\n   at System.Web.OData.Formatter.Deserialization.ODataResourceDeserializer.ReadResource(ODataResourceWrapper resourceWrapper, IEdmStructuredTypeReference structuredType, ODataDeserializerContext readContext)\r\n   at System.Web.OData.Formatter.ODataMediaTypeFormatter.ReadFromStream(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)"
    }
}

有人能帮我指定如何使用Dynamics Web API在
serviceendpoint
下注册
sdkmessageprocessingstep
吗？
可能是单值导航属性（查找）分配问题的问题，但错误消息有点不同

我还没有测试这个负载，所以请测试一下。顺便说一句，CRM REST builder在这些场景中有助于构建web api片段
