# Get a visitor's IP address and email it with Mandrill in Go on Heroku

I developed a simple web application in Go that when visited would find the visitor's IP address and email it via Mandrill. This application is a proof of concept, simply to try my hand at building an application in Go:

-   utilizing dependency management (i.e. GoDeps)
-   performing practical tasks like obtaining IP address information from behind a firewall (as with Nginx or Heroku)
-   interacting with an API, i.e. Mandrill
-   deploying a Go application to Heroku

This tool is ready to go out-of-the box—all that's required is setting some environment variables as per the documentation to customize it to work with your email address, redirect URL, and Mandrill account. [Check it out on Github](https://github.com/tinacious/go-get-ip).
