# ChannelParameters
<a name="API_ChannelParameters"></a>

The channel-specific parameters used to render and deliver a one-time passcode. Each member configures the parameters for one delivery route. Populate only the channels that a configuration or send request supports. A notify code configuration can carry every channel at once, and a send request resolves to a single route that selects the matching channel at send time.
