Hi,

Here is snippet code to send fax.

var attachment = new Attachment { fileName = "test.jpg", contentType = "image/jpeg", bytes = System.IO.File.ReadAllBytes("test.jpg") };
var attachments = new Attachment[] { attachment };
var body = new {
                 
               to = new CallerInfo[] { new CallerInfo { phoneNumber = RECIPIENT } },
               faxResolution = "High",
               coverPageText = "This is a demo Fax page from C Sharp"
               };
var resp = await rc.Restapi().Account().Extension().Fax().Post(body, attachments);

Hope this helps!

this is the exact code we're using. Kindly help me where things are going wrong

@RequestMapping(value = "sendFax", method = RequestMethod.POST)

@ResponseBody

public Response updateShoppingCart()

throws InvalidRequestException, ResourceMissingException, IOException, RestException, FileUploadException {

RestClient restClient = new RestClient(String clientId, String clientSecret, String server); //

restClient.authorize("", "101", "");

String endpoint = restClient.restApi("v1.0").account("~").extension("~").fax().endpoint();

QueryParameter[] qParam = new QueryParameter[3];

QueryParameter p0 = new QueryParameter("attachment", "");

QueryParameter p1 = new QueryParameter("faxResolution", "High");

// We can use any fax number we want here, BUT we need to use the "+1" + 10-digit format

QueryParameter p2 = new QueryParameter("to", "");

qParam[0] = p0;

qParam[1] = p1;

qParam[2] = p2;

ResponseBody responseBody = (ResponseBody) restClient.post(

restClient.restApi("v1.0").account("~").extension("~").fax().endpoint(),

qParam);

return new Response(Status.Success);

}

Sorry for misunderstood. I just quick looked at your code and thought that it was C#.

Here is the example to send a Fax message using the Java SDK.
