What do you mean by channel settings??

A channel might have the need to send notifications for various categories. For instance, Coindesk may wish to send notifications for tech, marketing, DeFi, and more. Similarly, Aave may want to send notifications for specific loan liquidation values.

Configuring settings for your channel empowers users to specify their preferences regarding the types of notifications they wish to receive and the timing of such notifications.

After enabling channel settings, you can retrieve the preferences of each user through the Fetch Subscription API. Additionally, you can initiate notifications targeted at specific settings categories using the Send Notification API.

Channel settings API

// creates channel settings
const createChannelSettingRes = userAlice.channel.settings([

    default: 1, 
    description: 'Receive marketing notifications' 
  },
  {
    type: 2, // Slider type
    default: 10,
    description: 'Notify when loan health breaches',
    data: { upper: 100, lower: 5, ticker: 1 },
  },
])

Types of channel settings

Push currently facilitates the configuration of the following settings for your channel:

• Boolean Setting - Users can express their preference as true or false. For instance, opting to receive marketing notifications.

• Slider Setting - Users can determine their preference within a specified range using a slider. For example, setting an alert for when an ENS domain expires, with a range of 1 to 7 days.
