Pushpad is a web push service that supports sending notifications to all major browsers (Chrome, Firefox, Edge, Safari, etc.) via FCM, Mozilla autopush, Windows Push Notification Services and Apple Push Notification service, with just one simple API. To configure the Pushpad integration, you will need an active account and you need to have a Pushpad Auth Token (from the account settings) and the Pushpad Project ID (from the project settings).

​
Setting the Device Token

Once Pushpad has been configured with your credentials and the Pushpad SDK has been set up and installed on your website, you can assign a user ID (uid) to the push subscriptions. This identifier (uid or user ID) allows targeting a specific browser when sending push notifications. In order to target the Pushpad user from Novu, you must register the Pushpad uid as the deviceToken for your Novu subscriber. For example, if you invoked the Pushpad JavaScript SDK with pushpad('uid', 'user123'), then user123 is the user ID for that browser. Once you have the uid value, the deviceToken for your Novu subscriber can be set using this code: 
import {
  Novu,
  ChatProviderIdEnum
} from '@novu/node';

const novu = new Novu("<NOVU_SECRET_KEY>");

await novu.subscribers.setCredentials('subscriberId', PushProviderIdEnum.Pushpad, {
// the user ID (uid) that you used for Pushpad
deviceTokens: ['user123'],
});
Checkout the API reference for more details.

​
SDK Trigger Example

import { Novu } from "@novu/node";

const novu = new Novu("<NOVU_SECRET_KEY>");

novu.trigger("<WORKFLOW_TRIGGER_IDENTIFIER>", {
  to: {
    subscriberId: "<SUBSCRIBER_ID>",
  },
  payload: {},
});
The devices of the subscriber that should receive the notifications can be set by using setCredentials or by using the deviceIdentifiers field in overrides.
