This script is used if Data tag sends a POST request or any additional functions are used (data hashing, data saving, etc.).
The script itself is not blocked by adblockers as far as it is known, but you may want to host it and specify the url to the script in this input. In this case the script will be loaded by the url you specify.
You don’t have to proxy it through sGTM, you can host the file on your web server for example.
uBlock is now blocking stapecdn.com. The file proxy power up is only available on the Business plan. And If we edit the Data Tag to add our domain to the Allowed URL field, we lose the ability to receive tag updates from Stape.
What is the solution?
Some of my clients are on the Pro plan and I do not have access to their domain/website. I was using jsDelivr to load the script, but I do not like that solution.
