400 Errors in /transientDocuments POSTS

[dadkind]

Hello All,

I'm working on my first Adobe Sign integration and I'm running into a sumbling block right off the bat.

I'm calling the /transientDocuments API and I keep getting a 400 Error or 415 error.

I'm coding in C# and using a WebClient to try to upload a document (the ultimate goal is to send an agreement to an end user).

Here is a snippet of code that throws a 400 error exception:

using(WebClient wc = new WebClient())
{

wc.Headers[HttpRequestHeader.Authorization] = string.Format("{0} {1}", accessToken.token_type, accessToken.access_token);
wc.Headers.Add("Content-Disposition", "form-data; name=\";File\";filename=\"" + model.EvalData.FileName + "\")");
wc.Headers.Add("Mime-Type", "application/pdf");
byte[] bResults = wc.UploadFile(endPoint, tempFileName);

}

I get this response:

Metadata
x-request-id : 53e8adb9-705f-441c-b2f5-8b6d0f651dd0
content-type : application/json
status : 400

Body
{
     "code": "NO_FILE_CONTENT",
     "message": "Must provide file body"
}

I've tried other variations of this code but keep getting the 400 or 415 errors.

Can someone please point out what I'm doing wrong here?

Thanks in advance,

Hey,
You must upload a file/ provide a file that's what you are missing.

Hey,

If you look at my code snippet, you will notice this line:

byte[] bResults = wc.UploadFile(endPoint, tempFileName);

This is the line at which my file is uploaded to the other endpoint.

I am sending a file. I have also uploaded it as a byte stream and I receive a 415 error (media type not supported).

Any other ideas?

Thanks,

Solved this by using the RestSharp library.

But beware, the field name for uploaded document must be "File" and is CASE SENSITIVE.

This is not mentioned in the Docs and wasted 2 days of time for me. So you are WARNED.

You are the man.  I can't believe calling it "file" vs "File" was the issue for me.  I've spent two days trying to get this working.

Can you provide a code snippet of the request. I have been trying to get this to work for 3 days. Thank you.

I hope you figured this out - it is indeed quite a very finnicky API. I am not OP, but here was my solution using RestSharp:

var client = new RestClient(_api_endpoint);
var request = new RestRequest("transientDocuments", RestSharp.Method.Post);

//Add auth token to header
request.AddHeader("Authorization", $"Bearer {auth_token}");

request.AddFile("File", "Form.pdf");  //Naming the file 'File' is VITAL for the API... for some reason
request.AlwaysMultipartFormData = true;

RestResponse response = await client.ExecuteAsync(request);

dynamic content = JsonConvert.DeserializeObject(response.Content);

String transientDocumentId = content.transientDocumentId;
