Did you try the Shopify provided URL to see if it works? The URL is automatically generated. What is it about the example URL you feel you need?

There is no way i can predetermine or set the URL of the uploaded file on Shopify. And Stripe requires I use that predetermined URL.
As I did not connect my domain yet with my Shopify shop, I uploaded the file on my domain now but once I connect it to Shopify that URL will stop working as all the traffic to my domain will be redirected to Shopify.
