This code snippet appears to be part of an HTML attribute (likely in a template engine used for dynamic web applications, such as Liquid or a similar syntax). Let me break it down:

Purpose:

The code dynamically generates a hyperlink (href) URL to an endpoint that appears to fetch or redirect to an invoice. This is likely used in an e-commerce context.

Components:

1. Base URL:

   https://ecommerceplugins.toconline.pt/invoice
   

   This is the base URL for the invoice generation or display service.

2. Query Parameters:

   • The URL contains dynamic query parameters that are populated with variables:
     • s={{ shop.url }}:
       • Replaces {{ shop.url }} with the value of the variable shop.url, which likely represents the URL or identifier of the specific online shop.
     • o={{ id }}:
       • Replaces {{ id }} with the value of the variable id, which probably represents an order ID or a unique identifier for the invoice.
     • d={{ created_at | date: '%s' }}:
       • Uses the created_at variable, which likely represents the timestamp at which the order was created, and formats it using the date filter into a Unix timestamp ('%s').

3. Template Engine:

   • The syntax {{ ... }} suggests that this code is written in a template engine (possibly Liquid, Django templates, or Jinja-like template formats). These template engines replace the placeholders with actual data at runtime.

4. Result: The resulting URL after rendering would look something like:

   https://ecommerceplugins.toconline.pt/invoice?s=<shop.url>&o=<id>&d=<unix_timestamp>
   

Final Functionality:

This code provides a dynamically generated link to an invoice page. The specific shop identifier (shop.url), order ID (id), and Unix timestamp representing the order's creation date (created_at) are inserted into the URL for the request to the invoice system.
