 This example uses [Twilio](https://www.twilio.com/) to save an image from your mobile phone to the AWS cloud. A user sends an image using MMS to a Twilio phone number which sends a request to an Amazon API Gateway endpoint that triggers a Lambda function. The app then returns a publicly accessible link to the image in AWS S3. This app uses AWS Lambda, API Gateway, DynamoDB & S3. It is also 100% serverless!
 
 NOTE: The project has been updated to use AWS Serverless Application Model (AWS SAM)

 Click Test. At the bottom of the page you view Execution result and the log output in Cloudwatch logs. This is very helpful for debugging.  
     5. Testing API Gateway requires a client that sends requests to the endpoint. I personally like the Chrome Extension [Advanced Rest Client](https://chrome.google.com/webstore/detail/advanced-rest-client/hgmloofddffdnphfgcellkdfbfbjeloo?hl=en-US) Send the endpoint a GET request and view its response. Ensure the S3 link works. You can also test by sending an MMS to phone number and checking the Twilio logs.

 1. Ensure your Lambda function is using the correct IAM role. The role must have the ability to write/read to DynamoDB and S3. 
 2. All Lambda interactions are logged in Cloudwatch logs. View the logs for debugging.
