twilio receive sms without responding back

问题

Good Day,

How do I properly receive an SMS on my web app using twilio without responding back to the sender.

I read about this.. https://support.twilio.com/hc/en-us/articles/223134127-Receive-SMS-messages-without-Responding but I need to use the webhook to send the sms to my webapplication too, if I do receive it without setting a response, It will generate an Error - 11200 (HTTP retrieval failure) how do I prevent this? also by setting up respones.

my code is

var resp = new twilio.twiml.MessagingResponse();
resp.message('<Response></Response>');
                      res.writeHead(200, {
                        'Content-Type':'text/xml'
                      });
                      res.end(resp.toString());

sadly this one sends <Response></Response> to the sender instead.. im using nodejs by the way.. Thanks!

I have not tried yet but I think if you comment out this line:

// resp.message("<Response></Response>");

no message will be sent.

Update after reading Phil's comment:

This: resp.message('<Response></Response>');

is equivalent with sending the folowing XML to Twilio:

<Response>
  <Response></Response>
</Response>

in which case the sender will receive a message like: <Response></Response>

If you comment out the line

// resp.message("<Response></Response>");

or if you do resp.message("");

is equivalent with sending the folowing XML to Twilio:

<Response />

in which case no message will be sent to the sender.
