TI通知回调接口失败

请求https://transact.ti.com/v2/store/subscriptions/inventory/test  接口返回

{
    "errors": [
        {
            "errorCode": "ERR-TICOM-INV-API-1002",
            "type": "ResourceNotFound",
            "section": "Path",
            "field": "tiPartNumber",
            "reason": "Resource could not be found",
            "message": "No active subscriptions found for tiPartNumber ('test'). Possible reasons: subscription was never created, subscription expired or was deleted, or part number is invalid or does not exist. Please verify the subscription details and resubmit your request."
        }
    ]
}
请问是什么原因?建议这个接口的文档完善下,请求此接口的参数需要传什么?ti通知推送时,推送的参数格式是什么?
