<Message>

The <Message> verb sends an SMS or MMS message to a phone number. To send a message in combination with Voice XML verbs, use the <Sms> Voice verb.

An example message that responds to the sender:

XML

<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Message>Hello from SignalWire!</Message>
</Response>

JavaScript

const { RestClient } = require("@signalwire/compatibility-api");
const response = new RestClient.LaML.MessagingResponse();

response.message("Hello from SignalWire!");
console.log(response.toString());

PHP

<?php
  use SignalWire\LaML;
  $response = new LaML;

  $response->message('Hello from SignalWire!');
  echo $response;
?>

C#

using Twilio.TwiML;

class Example
{
    static void Main()
    {
        var response = new MessagingResponse();
        response.Message("Hello from SignalWire!");

        Console.WriteLine(response.ToString());;
    }
}

Verb Attributes

Attribute
to optional	The to attribute takes a valid phone number in E.164 format as an argument. The message is sent to this phone number. If no to is specified, the message is sent as a reply to the incoming message sender.
from optional	The from attribute takes a valid phone number in E.164 format or short code. If no from is specified, it defaults to the number that received the message. You can only specify from phone numbers or short codes that you have purchased from SignalWire and which are capable of messaging.
action optional	The action attribute takes a URL endpoint that is expected to return a LaML document to override control flow. The endpoint receives a callback with the Standard Messaging Request Parameters as well as MessageStatus and ErrorCode and expect a valid LaML document in return. The next instructions to be executed are the verbs returned in response to the action endpoint request. For example, any verbs following a <Message> verb with its action attribute set are unreachable, as flow control will be passed onto the response from the action request.
method optional	The method attribute specifies whether the request to action is a GET or a POST. Valid values are GET or POST. Default value is POST.

Message Status

The MessageStatus parameter is sent with requests to the action endpoint or to statusCallback URLs. It determines whether the message was successfully sent or if there were problem with delivery.

Valid message statuses are: queued, sending, sent, failed, delivered

Nouns

puts response.to_s

The noun of a LaML verb is nested within the verb upon which the verb acts. <Message> has the following nouns:

Noun
plain text	The text of the message you want to send.
<Body>	The text of the message you want to send. If more than one <Body> noun is present, the text will be concatenated together into a single string. The maximum body size allowed is 1600 characters.
<Media>	The URL of media to include in the message. If you wish to send multiple media in a single message, use multiple <Media> nouns. You can have a maximum of 10 media URLs per message.

Nesting

No other verbs can be nested within <Message> and you cannot nest <Message> within any other verbs.

Add a picture to the message by specifying a URL with a nested <Media> noun. The <Body> noun is optional if you are sending media and you do not want to send text with your media in the message.

Send a Message and Respond Based on Status

XML

<?xml version="1.0" encoding="UTF-8"?>
<Response>
    <Message action="https://your-application.com/followup"
             method="GET">
        Hello from SignalWire!
    </Message>
    <Message>I am unreachable!</Message>
</Response>

JavaScript

const { RestClient } = require("@signalwire/compatibility-api");
const response = new RestClient.LaML.MessagingResponse();

response.message(
  { action: "https://your-application.com/followup", method: "GET" },
  "Hello from SignalWire!"
);
response.message("I am unreachable!");
console.log(response.toString());

PHP

<?php
  use SignalWire\LaML;
  $response = new LaML;

  $response->message('Hello from SignalWire!', array(
    'action' => 'https://your-application.com/followup',
    'method' => 'GET'
  ));
  $response->message('I am unreachable!');
  echo $response;
?>

C#

using Twilio.TwiML;
using Twilio.Http;
using System;


class Example
{
    static void Main()
    {
        var response = new MessagingResponse();
        response.Message("Hello from SignalWire!",
            action: new Uri("https://your-application.com/followup"), method: HttpMethod.Get);
        response.Message("I am unreachable!");

        Console.WriteLine(response.ToString());;
    }
}

Python

from twilio.twiml.messaging_response import Message, MessagingResponse

response = MessagingResponse()
response.message('Hello from SignalWire!', action='https://your-application.com/followup', method="GET")
response.message('I am unreachable!')

print(response)

Ruby

require 'signalwire/sdk'

response = Signalwire::Sdk::MessagingResponse.new do |response|
  response.message(action: 'https://your-application.com/followup', method: 'GET', message: 'Hello from SignalWire!')
  response.message(body: 'I am unreachable!')
end

puts response.to_s

This example allows us to follow up with further actions based on whether the message is sent or not. The URL https://your-application.com/followup receives a GET request with the message's parameters and includes the MessageStatus, either invalid, sending or failed.

The LaML document returned from your application determines what to do next. You could do nothing, or if the MessageStatus was failed, you could alert the user with a different <Message>.

With the action attribute is present, the remaining verbs in the document are unreachable because control is passed off to the response rather than continuing on in the document.
