Call Actor

This example demonstrates how to start an Apify actor using Apify.call() and how to call Apify API using Apify.client. The script extracts the current Bitcoin prices from Kraken.com and sends them to your email using the apify/send-mail actor.

To make the example work, you'll need an Apify Account. Go to Account - Integrations page to obtain your API token and set it to the APIFY_TOKEN environment variable, or run the script using the CLI. If you deploy this actor to the Apify Cloud then you can set up a scheduler for early morning.

To run this example on the Apify Platform, select the Node.js 8 + Chrome on Debian (apify/actor-node-chrome) base image on the source tab of your actor configuration.

const Apify = require('apify');

Apify.main(async () => {
    // Launch the web browser.
    const browser = await Apify.launchPuppeteer();

    console.log('Obtaining email address...');
    const user = await Apify.client.users.getUser();

    // Load Kraken.com charts and get last traded price of BTC
    console.log('Extracting data from kraken.com...');
    const page = await browser.newPage();
    await page.goto('https://www.kraken.com/charts');
    const tradedPricesHtml = await page.$eval('#ticker-top ul', el => el.outerHTML);

    // Send prices to your email. For that, you can use an actor we already
    // have available on the platform under the name: apify/send-mail.
    // The second parameter to the Apify.call() invocation is the actor's
    // desired input. You can find the required input parameters by checking
    // the actor's documentation page: https://apify.com/apify/send-mail
    console.log(`Sending email to ${user.email}...`);
    await Apify.call('apify/send-mail', {
        to: user.email,
        subject: 'Kraken.com BTC',
        html: `<h1>Kraken.com BTC</h1>${tradedPricesHtml}`,
    });

    console.log('Email sent. Good luck!');
});
