Create channel overview

This API is useful for creating a channel, which is the first step for sending a notification on Push Protocol.

Create channel API

Any protocol that wants to send a notification to their users needs to create a channel. A wallet can only have one channel.

js

// userAlice.channel.create({options})
const response = await userAlice.channel.create({
  name: "Test Channel",
  description: "Test Description",
  icon: "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAACAAAAAgCAYAAABzenr0AAAAz0lEQVR4AcXBsU0EQQyG0e+saWJ7oACiKYDMEZVs6GgSpC2BIhzRwAS0sgk9HKn3gpFOAv3v3V4/3+4U4Z1q5KTy42Ql940qvFONnFSGmCFmiN2+fj7uCBlihpgh1ngwcvKfwjuVIWaIGWKNB+GdauSk8uNkJfeNKryzYogZYoZY40m5b/wlQ8wQM8TayMlKeKcaOVkJ71QjJyuGmCFmiDUe+HFy4VyEd57hx0mV+0ZliBlihlgL71w4FyMnVXhnZeSkiu93qheuDDFDzBD7BcCyMAOfy204AAAAAElFTkSuQmCC",
