Not able to upload file on Autodesk forge server

Question

I want to convert rvt file into ifc file. For that I am using autodesk forge API.

Firstly I have created app on autodesk and after that creating token with below code:-

 const response = await 
   
  fetch('https://developer.api.autodesk.com/authentication/v2/token', 
   {
     method: 'POST',
     headers: {
         'Content-Type': 'application/x-www-form-urlencoded',
     },
     body: new URLSearchParams({
         "client_id": "myclientid",
         "client_secret": "myclientscert",
         "grant_type": 'client_credentials',
         "scope": 'bucket:create bucket:read data:write data:read'
       }),
   });

After that I have created a bucket with below code:-

  fetch('https://developer.api.autodesk.com/oss/v2/buckets', {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${data.access_token}`,
      'Content-Type': 'application/json'
  },
   body: JSON.stringify({
      bucketKey: bucketKey,
      policyKey: 'persistent'
   })
});
const bucket = await bucketresponse.json();

bucket is also created but When I am going to upload my rvt file then I am getting error like:

Status: 403 Forbidden ReasonPhrase: Forbidden "reason":"Legacy endpoint is deprecated

I am using below code to uplaod file.

 using (FileStream stream = new FileStream("D:\\Tech.rvt", FileMode.Open, FileAccess.Read))
 {

     var content = new StreamContent(stream);
     content.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream");

     var request = new HttpRequestMessage(HttpMethod.Put,
         $"https://developer.api.autodesk.com/oss/v2/buckets/{bucket}/objects/{Uri.EscapeDataString(fileName)}");
     request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token);
     request.Content = content;

     var response = await httpClient.PutAsync(request);
     var result = await response.Content.ReadAsStringAsync();
  
 }

Getting same error on Postman as well.

Please let me know What I am missing?

You need to generate a signed URL to upload your file in the bucket.

You can follow the instructions from https://aps.autodesk.com/en/docs/data/v2/tutorials/upload-file/#step-4-generate-a-signed-s3-url

You can also find a .NET example using our SDK at https://github.com/autodesk-platform-services/aps-sdk-net/blob/main/samples/oss.cs#L41-L53

For the Model Derivative part (conversion to IFC), you can use the Model Derivative SDK, as done at https://github.com/autodesk-platform-services/aps-sdk-net/blob/main/samples/modelderivative.cs#L31-L93

You just need to change the payload according to the RVT->IFC options
