Getting started

Besides Apify you need a SIGNL4 account. The SIGNL4 actor requires the SIGNL4 team or integration secret that you can obtain in SIGNL4.

To run the actor in Apify simply create a new task for the actor by clicking the green button above, modify the actor input configuration, click Run and get your results.

Send alerts

You can trigger an alert using a webhook from another Actor, e.g. when the Actor reaches a certain state. You obtain the webhook URL of the SIGNL4 Actor at API -> API endpoints. The Payload template might look like follows:

1{
2    "userId": {{userId}},
3    "createdAt": {{createdAt}},
4    "eventType": {{eventType}},
5    "eventData": {{eventData}},
6    "resource": {{resource}},
7    "secret": "your-signl4-team-or-integration-secre",
8    "title": "Web Scraper Alert from Apify",
9    "data": {{eventData}}
10}

Alternatively, you can trigger the alert within the code of another Actor like this:

1import { Actor } from 'apify';
2await Actor.init();
3
4// Send SIGNL4 alert
5await Actor.call('roncz/signl4', {
6    secret: 'your-signl4-team-or-integration-secret',
7    title: 'Web Scraper Alert from Apify',
8    message: "Web scraper content available.",
9    data: headingObject
10});
11
12await Actor.exit();

Use cases

Sending automated alerts from Apify has several benefits. Users can react to critical situations quickly and to take according action. Here come some sample use cases:

• Alerts on certain Actor states, e.g. failures
• Web scraping alerts, e.g. if a web page changes or if a certain value or price reaches a threshold
• Use Robotic Process Automation (RPA) to monitor your web workflows and alert admins if a workflow fails (before your customers will recognize)
• Integrate with other tools including AI (ChatGPT, LLMs) to create powerful alerting workflows
