SENDING SMS VIA TWILIO USING PHP
Twilio’s Programmable SMS API helps you add robust messaging capabilities to your applications.
Using this REST API, you can send and receive SMS messages, track the delivery of sent messages, Schedule SMS mesages to send at a later time, and retrieve and modify message history.
The API is served over HTTPS. To ensure data privacy, unencrypted HTTP is not supported.
Send messages with the SMS API
Twilio will now monitor messages to prevent content violating our Acceptable Use Policy (AUP).
This helps to ensure and support Twilio Messaging as a trustworthy, high engagement channel and will not slow down the delivery of messages.
If a message you send has violated the AUP, it will be returned and you will receive an error code which identifies the necessary changes you need to make sending it again.
