需要有关SSG WSG API的Grant Calculator API的帮助

Question

我正在尝试使用证书API的Grant Calculator API

URL为：https://api.ssg-wsg.sg/grantCalculators/individual 正文是：

{
  "courses": [
    {
      "trainingProviderUen": "2012017XXX",
      "courseReferenceNumber": "TGS-2015502710"
    }
  ]
}

但是，每次我得到

{
    "status": 400,
    "errors": {
        "details": [
            {
                "courseReferenceNumber": "TGS-2015502710",
                "message": "Course funding eligibility cannot be determined based on parameters submitted"
            }
        ],
        "message": "Unsuccessful request"
    }
}

我们非常感谢您的帮助。
