Step-by-step workflow explanation

Input collection

The workflow starts with a Webhook node that opens a form for users.

Users pick deal categories such as Appliances, Cameras, or Cell Phones and enter their email address.

Scraping offers

The BrightData node accesses MediaMarkt's campaign page while bypassing web restrictions.

The output is the raw HTML page content containing deals.

Parsing HTML content

An HTML Extract node grabs the page title and body text for further analysis.

Classifying and translating deals

The extracted body HTML and user category choices feed into the OpenAI LangChain node.

This node uses the GPT-4o-mini model with a specially crafted prompt to sort deals into categories and translate details into English JSON format.

Breaking down deals

A SplitOut node separates the returned JSON array of deals into individual entries to work with.

Generating email content

A Document Generator node uses a template listing each deal with category, link, name, and price in HTML.

<br>
These are our recommended deals today:<br>
<ul>
{{#each items}}
<li>: <a href="https://www.bestbuy.com"></a> for €</li>
{{/each}}
</ul>
<br>

This creates an easy-to-read email body showing the best offers.

Sending the email

The EmailSend node sends the deals email using SMTP.

It uses the user's email from the form data as the recipient.

Showing confirmation

The final Form Completion node displays a thank-you page, telling users how many deals were emailed.

Edge cases and troubleshooting

• Empty BrightData results: Check correct zone setup and BrightData API usage limits.
  


• Malformed OpenAI JSON: Verify system prompt correctness and make sure the HTML input to OpenAI is well parsed.
  


• Email delivery issues: Confirm SMTP settings and email sender address are valid; test with simple emails first.
  

Customization ideas

• Add more categories like Smart Home or Wearables in the form trigger for more tailored deals.
  


• Change the BrightData scraping URL to other retailer campaign pages with similar HTML.
  


• Edit the Document Generator template to include images or discount percentages in deal emails.
  


• Set up a timer trigger to run this workflow daily for automatic deal alerts.
  


• Integrate Slack node to send notifications when new deal emails go out.
