• Add a service bus connection string in your local.settings.json file

{
  "IsEncrypted": false,
  "Values": {
	... // other environment variables
	"ServiceBus__ConnectionString": "Endpoint=sb://my-service-bus.servicebus.windows.net/;SharedAccessKeyName=RootManageSharedAccessKey;SharedAccessKey=MY_SECRET_KEY"
    "ServiceBus__Queue__Normal": "normal.queue.name",
    "ServiceBus__Queue__Rejected": "rejected.queue.name"
  }
}

Create a message

Send a post message to CreateServiceBusMessage function

[POST] http://localhost:7240/api/CreateServiceBusMessage

{
    "message": "test",
    "value": 5
}

or using curl

curl -X POST http://localhost:7240/api/CreateServiceBusMessage -H "Content-Type: application/json" -d "{ 'message': 'Hello World!', 'value': 5 }"
