Send notification interface

interface INotification {
  title: string;
  body: string;
}

interface IPayload {
  title?: string;
  body?: string;
  cta?: string;
  embed?: string;
  category?: number;
  meta?: {
    domain?: string;
    type: string;
    data: string;
  };
}

interface IConfig {
  expiry?: number;
  silent?: boolean;
  hidden?: boolean;
}

interface IAdvanced {
  graph?: {
    id: string;
    counter: number;
  };
  ipfs?: string;
  minimal?: string;
  chatid?: string;
  pgpPrivateKey?: string;
}

interface NotificationOptions = {
  notification: INotification;
  payload?: IPayload;
  config?: IConfig;
  advanced?: IAdvance;
  channel?: string;
};

// Usage example:
const apiResponse: ApiResponse = await userAlice.channel.send(recipients, {
  // NotificationOptions - as per your given object structure
});

Encrypted notification example

Push Protocol supports sending encrypted notifications, which can only be decrypted by the intended recipients. You can send encrypted notifications to targeted/subsets of users. Currently, Push Notification supports two encryption standards: PGPV1 and LITV1. Use LITV1 to use Lit Protocol encryption and PGPV1 to use PGP_V1 encryption.

js

// userAlice.channel.send([recipients], {options?})
const sendNotifRes = await userAlice.channel.send(["AliceWalletAddress"], {
  notification: { title: "test", body: "test" },
  secret: "PGPV1", // or "LITV1"
});
