Example Event Grid Application

This is an example application that will leverage a custom message to retrieve an image, copy it to blob storage and invoke the vision API to caption it.

To work, you must take a few steps:

1. Create a custom Event topic you use to publish the message to
2. Create a cognitive services Vision API endpoint
3. Build a logic app to receive events and update the captions

The logic app looks like this:

You also need to update the console app to point to your Event topic end point, and set environment variable EVENT_GRID_KEY to the key for the topic.
