What languages does Twilio use?
Any stack of web software works, as long as it can receive an HTTP request and respond with valid XML. We have helper libraries that make common tasks easy in PHP, Python, Ruby, . NET, Java, Apex, and C#.
What protocol does Twilio use?
That message will then get routed to Twilio via a protocol called SMPP, the protocol for text messaging. Twilio receives the message from the carrier over a dedicated connection between Twilio and that carrier.
Why is Twilio so good?
Twilio offers a CPaaS and CCaaS solution, with the combination of its programmable Voice, Video, and Messaging APIs, as well as the Twilio Flex cloud contact center. Additional capabilities include Twilio's Elastic SIP Trunking, as well as API for WhatsApp.
