Ready solution: Bypassing Safari blocks (ITP) and integration G

Short description of the solution:
This is a ready-made technical complex for cross-analytics that fully addresses the issue of cookie deletion in modern browsers (especially Safari with ITP protocols that erase data within 1-7 days). Due to these limitations, businesses lose information about which specific advertisement the client came from if the purchase did not occur on the first day.

How it works technically:
1. Lossless tag storage: A custom JavaScript script reads all marketing data (utm_source, utm_medium, utm_campaign, utm_content, utm_term, gclid, fbclid, fbp, fbc, user_agent) from the URL and stores it in the browser's secure LocalStorage. There, the data is stored for months, even if the client clears classic cookies.

2. Automation in Google Tag Manager (GTM): The script operates through GTM, automatically monitors the appearance of any forms and embedded GetCourse widgets on the page, and independently injects the saved marketing tags directly before the form is submitted by the client.

3. Server integration (Webhook): On the GetCourse side, an automatic process is set up that, at the moment of a real change in the order status (e.g., "Paid"), instantly sends a clean JSON package to the client's analytics or CRM server, transmitting contacts, amount, currency, and initial advertising tags.

What the client receives:
A fully configured tracking system with zero loss of marketing data. Each payment in GetCourse is guaranteed to be linked to a specific ad click, regardless of which browser the buyer used and how much time has passed from the click to the purchase.
Be cautious when using the code.
