# Send SMS Message with Twilio This example demonstrates how to send SMS messages with the Twilio SDK and AWS lambda. [Live the live demo](http://twilio-serverless-example.surge.sh) ## Use Cases: * Sending users confirmation text messages ## Setup 1. Sign up for a [Twilio account](http://www.twilio.com) 2. Create a [new phone number](https://www.twilio.com/console/phone-numbers/) in your Twilio trial account 3. Grab your ACCOUNT SID and AUTH TOKEN from the [Twilio console](https://www.twilio.com/console) and plug those into the `serverless.yml` file in the next step 4. Set your `env` variables in `serverless.yml` with your Twilio account values ```yml environment: # replace these env variables with your twilio account values TWILIO_ACCOUNT_SID: YOUR-TWILIO-ACCOUNT-SID-HERE TWILIO_AUTH_TOKEN: YOUR-TWILIO-AUTH-TOKEN-HERE TWILIO_PHONE_NUMBER: YOUR-TWILIO-PHONE-NUMBER-HERE ``` If you want to use encrypted API keys, see our [encrypted environment variables example](https://github.com/serverless/examples/tree/master/aws-node-env-variables-encrypted-in-a-file) 5. Invoke the function and send an SMS message Update the `to` phone number the `event.json` file and `message` to send in the SMS Then invoke the function with the serverless CLI. Set the `--path event.json` so the function knows where to send the SMS. ```bash serverless invoke -f sendText --path event.json ``` 6. (Optional) Deploy the front-end application Update the `API_ENDPOINT` variable in the `/frontend/index.html` file and deploy the `/frontend` folder to a static host of your choice. We recommend S3, [netlify](https://www.netlify.com/), or [surge.sh](http://surge.sh/) for quick and easy static site hosting.
