<Message> verb sends a message to a phone number or a

<Message> verb supports the following attributes that modify its behavior:
|Attribute Name||Allowed Values||Default Value|
|to||phone number, Wireless SIM Sid||see below|
|from||phone number, 1-11 character string (A-Z, a-z, 0-9), Wireless SIM Sid||see below|
|action||relative or absolute URL||none|
The 'to' attribute takes a valid phone number as an argument. Twilio will send the message to the number provided. If no 'to' attribute is provided, Twilio will send the message as a reply to the current sender.
Phone numbers should be formatted with a '+' and country code e.g.,
+16175551212 (E.164 format). For 'to' numbers without a '+',
Twilio will use the same country code as the 'from' number. Twilio will
also attempt to handle locally formatted numbers for that country code
(e.g. (415) 555-1212 for US, 07400123456 for GB). If you are sending to
a different country than the 'from' number, you must include a '+'
and the country code to ensure proper delivery.
If you have a trial account, the
to phone number must be verified with Twilio. But you don't need to specify the
to attribute to just send a message reply to the current sender.
For details on sending to a Wireless SIM, see "Messages to the Device" in the Wireless Programmable SMS documentation.
The 'from' attribute takes a valid phone number or alphanumeric sender ID as an argument. If a phone number is used, it must be a number that you've purchased from or ported to Twilio.
Alphanumeric sender IDs can only be used when sending messages to countries where the feature is supported. Alphanumeric sender IDs are limited to 11 characters. Accepted characters include both upper- and lower-case ASCII letters, the digits 0 through 9, and space: [A-Za-z0-9 ]. The sender ID must represent or be associated with your company brand.
When sending a message in response to an incoming message, 'from' defaults to the
Twilio number that received the message. If you specify a 'from' value, it must
be a message-capable local phone number assigned to your account. If the phone
number isn't message-capable, then
<Message> will not send a message.
The 'action' attribute takes a URL as an argument. Like the
StatusCallback parameter when sending an outbound message via the REST API, this URL will receive an HTTP request with the status of a message sent in response to an inbound message.
The possible statuses for a message are
undelivered. Twilio will send the
MessageSid along with the other standard request parameters as well as
ErrorCode. Non-relative URLs must contain a valid hostname (underscores are not permitted).
The HTTP method used to make the request is configured in the method property.
The 'method' attribute takes the value 'GET' or 'POST'. This tells Twilio
whether to request the
action URL via HTTP GET or POST. This attribute
is modeled after the HTML form 'method' attribute. 'POST' is the default value.
MessageStatus parameter is sent with requests to the
action URL or to the
statusCallback URL. The parameter contains more information about the status
of the message - whether it was successfully sent, or whether delivery
failed (the number was invalid, or there was no message body, etc.)
|MessageStatus||The current status of the message. Either
The "noun" of a TwiML verb is the stuff nested within the verb that's not a verb itself; it's the stuff the verb acts upon. These are the nouns for
|plain text||The text of the message you want to send. Must be less than 1600 characters.|
|<Body>||The text of the message you want to send. Must be less than 1600 characters. If more than one <Body> element is used in a single <Message> the contents of the two will be concatenated together into a single Body value.|
|<Media>||A nested XML element that indicates the URL of a image to be sent in the message. If you wish to send more than one image please include more than one <Media> element. The maximum number of <Media> that can be included in a given message is 10.|
Want to send a message without waiting for an inbound message? See our outbound message documentation.
To add a picture to the message, you can specify a URL with the Media noun. You can also enclose the body in the Body noun. If you specify one or more Media nouns, the Body is optional.
In this use case, we have provided 'action' URL and 'method' attributes. Now when the message is queued for delivery, Twilio will request the 'action' URL passing the parameter 'MessageStatus'. If the messages are queued and waiting to be sent, 'MessageStatus' will have the value 'sending'. If an invalid attribute was provided, then 'MessageStatus' will be 'invalid'.
Your web application can look at the 'MessageStatus' parameter and decide what TwiML to return.
If an 'action' URL is provided for
<Message>, the flow of your application will continue with the TwiML received in response to the 'action' request.
All verbs remaining in the document will be unreachable and ignored.
You can't nest any verbs within
<Message> and you can't nest
<Message> in any other verbs. The only elements that can be nested within a
