  ## Collect data through Channel
  
  The Event API support optional `channel` query parameter. This allows you to import and query events of this specific channel. When the `channel` parameter is specified, the data is collected through the default channel.
  
  URL: `http://localhost:7070/events.json?accessKey=yourAccessKeyString&channel=yourChannelName`
  
  
negative.code: title: Channel
  ---
  
  Each App has a default channel (without name) which stores all incoming events. This "default" one is used when channel is not specified.
  
  You may create additional Channels for the App. Creating multiple Channels is advanced usage. You don't need to create any in order to use PredictionIO. The Channel is associated with one App only and must have unique name within the same App.
  
  Creating multiple Channels allows you more easily to identify, manage and use specific event data if you may collect events from different multiple sources (eg. mobile, website, or third-party webhooks service) for the your application.
  
  (More usage details coming soon...)
  
  ## Create a new Channel
  
  For example, to create a new channel "myChannel" for app "myApp", run following `pio` command:
  
  ```
  pio app channel-new myApp myChannel
