Generate a unique URL that can be presented to the user to complete the purchase.
Caution
This is a server side API. Always call this endpoint from the game server and push the URL to the game client. Never store your API secret on the game client.
Requests require a valid secret to be passed in the Authorization header. You can generate your credentials in Stash Studio.
Ensure you're redirecting to the URL on the client side correctly (new window, new tab or popup window). Rendering the checkout as an iFrame or embedding it in any way is not supported and likely to cause unforeseen issues.
