Message (SMS) Attributes
To: The 'to' attribute takes a valid E.164 phone number as a value. Callapi will send an SMS message to this number. When sending an SMS during an incoming call, 'to' defaults to the caller. When sending an SMS during an outgoing call, 'to' defaults to the called party. The value of 'to' must be a valid phone number.
From: The 'from' attribute takes a valid E.164 phone number as an argument. When sending an SMS during an incoming call, 'from' defaults to the calling party. When sending an SMS during an outgoing call, 'from' defaults to the called party.
Action: The action attribute takes a URL address as an argument. After processing the verb, CPaaS will make a POST request to this URL with the form parameters 'SmsStatus' and 'SmsSid'. Using an 'action' URL, your application can receive synchronous notification that the message was successfully enqueued or not.
None of these are required, or you can send only one or the other. If they are blank, the system will determine if you called them or they called you, and send the message appropriately. This allows you to change the from if required.
