Click the "Deploy to Azure" button above. You can create new resources or reference existing ones (resource group, gateway, service plan, etc.) Site Name and Gateway must be unique URL hostnames. The deployment script will deploy the following:
- Resource Group (optional)
- Service Plan (if you don't reference exisiting one)
- Gateway (if you don't reference existing one)
- API App (EventHubAPI)
- API App Host (this is the site behind the api app that this github code deploys to)
The app has one webhook trigger (Receive Message) and one action (Send Message)
The trigger has the following inputs
| Input | Description |
|---|---|
| Connection String | The connection string to access the event hub. |
| Event Hub Name | Name of the event hub (e.g. myeventhub ) |
| Consumer Group | Name of the consumer group the API App will subscribe to for messages (uses default consumer group if left blank) |
| Partition List (optional) | A comma separated list of the partitions to subscribe to (e.g. 1,2,3,4,6,7,8). Leaving blank will subscribe to all available partitions for the Event Hub. |
The trigger will return the message as @{triggerBody()}. It is returned as a JToken, so you can parse through the JSON like @{triggerBody()[0].eventtoken}.

"subscribe": {
"body": {
"callbackUrl": "@{listCallbackUrl()}",
"eventHubConnectionString": "Endpoint=sb://[namespace].servicebus.windows.net/;SharedAccessKeyName=[keyname];SharedAccessKey=[key]",
"eventHubName": "[hubname]"
},
"headers": {
"content-type": "application/json"
