I have the following curl request which is working nicely and as supposed:

curl --user 'api:MY_API_KEY'
https://api.mailgun.net/v3/mydomain/messages --form from='My Name
' --form to=validaddress@domain.com --form
subject='Hello 3!' --form text='Testing sending email!'

However I need to craft this request as a valid https request using the standard https module form nodejs, and I tried the following code, however I keep getting 400 (bad request) as response:

helpers.sendRequestFormData = function(protocol, port, hostname, method, path, contentType, auth, timeoutSeconds, postData, callback)
 var from = 'My Name <info@mydomain>';
 var to = 'validaddress@domain.com';
 var subject = 'Email test';
 var text = 'Testing sending email';

 var stringPayload = `--$config.mailgun.boundary
 nContent-Disposition: form-data; name="from";
 nContent-type: multipart/form-data;
 nfrom="$from";
 n--$config.mailgun.boundary
 nContent-Disposition: form-data; name="to";
 nContent-type: multipart/form-data;
 nto="$to";
 n--$config.mailgun.boundary
 nContent-Disposition: form-data; name="subject";
 nContent-type: multipart/form-data;
 nsubject="$subject";
 n--$config.mailgun.boundary
 nContent-Disposition: form-data; name="text";
 nContent-type: multipart/form-data;
 ntext="$text";
 n--$config.mailgun.boundaryn`;

 // Construct the request
 var requestDetails = 
 'hostname' : hostname,
 'port': port,
 'method' : method,
 'timeout' : timeoutSeconds * 1000,
 'path' : path,
 'headers' : 
 'Authorization': auth,
 'Content-Type': contentType,
 'Content-Length': Buffer.byteLength(stringPayload)
 
 ;

 // Instantiate the request object (using either the http or https module)
 var _moduleToUse = protocol == 'http' ? http : https;
 var req = _moduleToUse.request(requestDetails, function(res)

 var responseStatus = res.statusCode;
 console.log(responseStatus);

 res.setEncoding('utf8');
 res.on('data', function(data)

 if(requestStatus == 200)
 callback(false, parsedData);
 

 );
 );

 // Bind to the error event so it doesn't get thrown
 req.on('error',function(e)
 console.log(e);
 callback(true, 'Error': e);
 );

 // Bind to the timeout event
 req.on('timeout',function()
 console.log('timeout');
 callback(true, 'Error': 'The request took much time and got timeout.')
 );

 // Add the payload
 req.write(stringPayload);

 // End the request
 req.end();
 ;

Can someone please give me some hints, guidance, or tips? I am getting a bit overwhelmed about this, I am sure it might be something simple, been doing trial and error with semi-colons and dashes on the boundary but still didn't got a 200 status response code.

Thank you so much in advance!

I made it working, the current code is the following:

helpers.sendRequest = function(protocol, port, hostname, method, path, 

contentType, auth, timeoutSeconds, postData, callback)
 var stringPayload = querystring.stringify(postData);

 // Construct the request
 var requestDetails = 
 'hostname' : hostname,
 'port': port,
 'method' : method,
 'timeout' : timeoutSeconds * 1000,
 'path' : path
 ;

 // Instantiate the request object (using either the http or https module)
 var _moduleToUse = protocol == 'http' ? http : https;
 var req = _moduleToUse.request(requestDetails, function(res)
 res.on('data', (d) => 
 if(res.statusCode == 200)
 callback(false);
 else
 console.log(res.statusCode);
 callback(true);
 
 );
 );

 req.setHeader('Authorization', auth);
 req.setHeader('Content-Type', contentType);
 req.setHeader('Content-Length', Buffer.byteLength(stringPayload));

 // Add the payload
 req.write(stringPayload);

 // Bind to the error event so it doesn't get thrown
 req.on('error',function(e)
 console.log(e);
 callback(true, 'Error': e);
 );

 // Bind to the timeout event
 req.on('timeout',function()
 console.log('timeout');
 callback(true, 'Error': 'The request took much time and got timeout.')
 );

 // End the request
 req.end();
 ;

And I call the method like this:

genericHelper.sendRequest('https', '443', 'api.mailgun.net', 'POST', '/v3/sandbox0630029a67f24517a9c3e383d2c6098e.mailgun.org/messages',
 'application/x-www-form-urlencoded', ('Basic ' + Buffer.from(('api:'+ config.mailgun.ApiKeyTest)).toString('base64')), 5, emailRequestObject, function(err, data)

// Here I do what I need after sending the http request with success

);

I hope it helps someone out, so the problem was the content-type, I had to change it to 'application/x-www-form-urlencoded' and then also the authorization I had to convert to Base64 and include Basic before the pair in base64.
