 # Introduction
 
-This is an example project for using a Docker container as a [SendGrid](https://sendgrid.com) [inbound parse email](https://sendgrid.com/docs/for-developers/parsing-email/setting-up-the-inbound-parse-webhook/) webhooks.
+This is an example project for using a Docker container as a [SendGrid](https://sendgrid.com) [inbound parse email](https://sendgrid.com/docs/for-developers/parsing-email/setting-up-the-inbound-parse-webhook/) webhooks and [event webhooks](https://sendgrid.com/docs/for-developers/tracking-events/getting-started-event-webhook/)
 
 # Prerequisites
 
 * [Docker CE 18](https://www.docker.com/get-started)
 * (Optional for development) A local Kubernetes installation
 * SendGrid Account with inbound parse enabled to send form data (default)
     * [Setup Inbound Parse Webhook](https://sendgrid.com/docs/for-developers/parsing-email/setting-up-the-inbound-parse-webhook/)
+* SendGrid Account with event webhooks enabled
+    * [Getting Started with Event Webhook](https://sendgrid.com/docs/for-developers/tracking-events/getting-started-event-webhook/)
 * [Ngrok](https://ngrok.com/) or Internet accessible URL

 NOTE: ngrok has a "replay" feature so you don't have to keep sending emails to yourself.  You can access that when ngrok is running at [http://127.0.0.1:4040/inspect/http](http://127.0.0.1:4040/inspect/http)
 
 # Modifying the application
 
-At the moment, the `app.js` only prints data to the console.  You can extend this project by adding more business logic to the `/parse_webhook` route.
+At the moment, the `app.js` only prints data to the console.  You can extend this project by adding more business logic to the `/parse_webhook` or `/event_webhook` routes, contained in the [routes/inbound-parse.js](routes/inbound-parse.js) and [routes/events.js](routes/events.js).
 
 ## A note on processing events
-
-This project uses the [express-formidable](https://github.com/utatti/express-formidable) middleware to process the form data sent by SendGrid's Inbound Parse Webhook.  
+
+### Inbound Parse Webhook
+
+The [routes/inbound-parse.js](routes/inbound-parse.js) route uses the [express-formidable](https://github.com/utatti/express-formidable) middleware to process the form data sent by SendGrid's Inbound Parse Webhook.  
 
 The events are available in the `/parse_webhook` route in the `req.fields` object.  The [app.js](app.js) contains logging statements for the elements that are available to you.  It may be useful to review the [example-webhook-payload.txt](example-webhook-payload.txt) for what the form data looks like when extending this application.

+### Events Webhook
+
+The [routes/events.js](routes/events.js) route receives data in JSON format.

 Additionally, the [docker-compose](docker-compose.yml) has a volume mapping commented out if you'd prefer to store them in persistent storage outside of the container.
