I've created a small AWS Lambda that sends an email using SES. I'm looking to hookup a contact us form from a static website to this lambda.

Is it possible to have the contact us form post directly to a url of the lambda? I'm not using a server side framework and would really like to avoid it, what are my options? Is there client side Javascript way to invoke the lambda?

Wrote a blog post about this.

This is totally doable. It's a matter of using AWS Cognito to call that function.

1. You have your lambda function in place. Grand.
2. Create a new Cognito group.
3. Give the unauth'ed Cognito group permissions to execute the lambda function.
4. Wire it all up in the browser. I have some example code here… https://github./chadbaudoin/lambda-twilio/blob/master/index.html

The “hard” part is making sure that the IAM settings for the Cognito group and the Lambda function are all set up correctly. I used this tutorial pretty heavily, but used cognito to execute so I wasn't exposing keys.
