Create subscription

Subscribes a listener application to receive change notifications when new messages are created for the user (that includes sent and received messages).

import { GraphClient } from '../independentsoft/graph/graph.js';
import { Subscription, ChangeType } from '../independentsoft/graph/change-notifications.js';

async function mainFunc() {

    try {
        const client = new GraphClient();
        client.clientId = "xxxxxxxxxx-209e-454e-xxxxxxxxxxxxxxxxxxx";
        client.tenant = "independentsoft.onmicrosoft.com";
        client.clientSecret = "xxxxxxxxx.ONVE[=zYYxxxxxxxxxxxxxxxx";

        const now = new Date();
        const expirationTime = new Date(now.getFullYear(), now.getMonth(),  now.getDate() + 1);

        let subscription1 = new Subscription();
        subscription1.changeTypes.push(ChangeType.CREATED);
        subscription1.resource = "/users/info@independentsoft.onmicrosoft.com/messages";
        subscription1.notificationUrl = "https://webhook.site/#!/6cbb255e-76e4-4f3c-89cd-xxxxxxx";
        subscription1.clientState = "123456789";
        subscription1.expirationTime = expirationTime;

        const createdSubscription = await client.createSubscription(subscription1);

        console.log("Id: " + createdSubscription.id);
        console.log("ExpirationTime: " + createdSubscription.expirationTime);
    }
    catch (e) {
        console.error(e.code)    //error code
        console.error(e.message) //description
        console.error(e.date)    //timestamp
        console.error(e.innerError)   //innerError
    }
}
