positive.code: 
  ## 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: Field | Type | Description
  :---- | :----| :-----
  `accessKey` | String | The Access Key for your App
  `channel` | String | The channel name (optional). Specify this to import data to this channel. **NOTE: supported in PIO version >= 0.9.2** only. Channel must be created first.
  
  
  For SDK usage, one EventClient should be responsible for collecting data of one specific channel. The channel name is specified when the EventClient object is instantiated.
  
  For example, the following code import event to "YOUR_CHANNEL" of the corresponding App.
  
  <div class="tabs">
    <div data-tab="Raw HTTP" data-lang="bash">
  ```bash
  $ curl -i -X POST http://localhost:7070/events.json?accessKey=YOUR_ACCESS_KEY&channel=YOUR_CHANNEL \
  -H "Content-Type: application/json" \

    "event" : "my_event",
