Starts on an incoming request

This workflow automates the process of sending voice calls for verification purposes and combines it with email verification. It uses the ClickSend API for voice calls and integrates with SMTP for email verification. This workflow is a powerful tool for automating phone and email verification, ensuring a seamless and secure user verification process. Below is a breakdown of the workflow: 1. How It Works The workflow is designed to verify a user's phone number and email address through a combination of voice calls and email verification. Here's how it works: Form Submission: The workflow starts with a Form Trigger node, where users submit a form with the following fields: To: The recipient's phone number (including the international prefix, e.g., +1xxxx). Voice: The voice type (male or female). Lang: The language for the voice call (e.g., en-us, it-it, fr-fr, etc.). Email: The recipient's email address. Name: The recipient's name. Set Voice Code: The Set Voice Code node defines the verification code that will be spoken during the voice call.

Track changes of product prices

This workflow automatically tracks changes on specific websites, typically in e-commerce where you want to get information about price changes. Prerequisites Basic knowledge of HTML and JavaScript Nodes Execute Command nodes create a file named kopacky.json in the /data/ folder (Make sure that n8n has the permissions to make changes to the folder in your setup) and clean data. Cron node triggers the workflow at regular intervals (default is 15 minutes), depending on how often you want to crawl URLs of your watchers. Function Item node (Change me) adds the URL watchers. You can put as many URLs (watchers) as you want by changing the JavaScript code in the node. There are four properties for each watcher: |Property|Meaning| |-|-| |slug|Unique identifier for the watcher.| |link|URL of the website where you want to track changes.| |selector|CSS selector of the HTML tag, where your price is placed. You can use browser web tools to get a specific selector.| |currency|Currency code in which your price is set.| Function Item node (Init item) saves all required data from each watcher to the kopacky.json file. HTTP Request node fetches data from the website. HTML Extract node extracts the re
