Send an SMS Message with Kotlin in 30 Seconds

You’re building a Kotlin app, and you need to send SMS messages. What if I said you can get it done in 30 seconds with the Twilio API? Here’s a video showing you how quick it is to send an SMS message with Kotlin and the Twilio API.

Video: How To Send SMS with Kotlin in 30 Seconds

But you can’t copy and paste from a video, so here’s all the code you will need. Or you can just get it from this repository.

Add the Twilio helper library for Java to your Gradle or Maven file.

compile group: "com.twilio.sdk", name: "twilio", version: "7.17.+"

Initialise the Twilio REST Client passing your Account SID and Auth Token, which are available on the Twilio Console.

import com.twilio.Twilio

fun main(args:Array<String>){
    Twilio.init(
            System.getenv("TWILIO_ACCOUNT_SID"),
            System.getenv("TWILIO_AUTH_TOKEN")
    )
}

You will need three things now:

The phone number you are sending the message to
The Twilio number you are sending the message from
The body of the message

Add those into the Message.creator method and it will send a text message:

val message = Message.creator(
            PhoneNumber("** YOUR PHONE NUMBER **"),
            PhoneNumber("** YOUR TWILIO PHONE NUMBER **"),
            "Ahoy from Twilio"
    ).create()

Now run it by pressing the green arrow next to your function definition.
