Building a Twilio SMS Sender in Go: A Practical Guide

This code package contains a simple HTTP server that can receive POST requests and send SMS messages using Twilio API.

Setup

To use this code package, you need to set your Twilio Account SID and Auth Token as environment variables. You can do this by running the following commands in your terminal:

export TWILIO_ACCOUNT_SID=your_account_sid
export TWILIO_AUTH_TOKEN=your_auth_token

Replace your_account_sid and your_auth_token with your actual Twilio credentials.

Usage

Once you have set your Twilio credentials, you can start the server by running the following command:

go run main.go

This will start the server on port 8080. You can then send a POST request to http://localhost:8080/sms with the following JSON payload:

{
"to": "+1234567890",
"body": "Hello from Twilio!"
}

Replace +1234567890 with the phone number you want to send the SMS to, and replace Hello from Twilio! with the message you want to send.

Alternatively, you can use the following curl command to send the POST request:

curl -X POST -H "Content-Type: application/json" -d '{"to": "+1234567890", "body": "Hello, Golang!"}' http://localhost:8080/sms

The server will then use the Twilio API to send the SMS, and return a JSON response with the message ID:

{
"message_id": "SMXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
}
