I'm building an app that integrates with eBay's trading API and I'd like to manual test that my notifications are set up. Fundamentally the app synchronizes listings (AddFixedPriceItem) and subscribes to sales notifications (SetNotificationPreferences using ItemSold). I've read a lot of documentation that states that the Ebay sandbox is at near-parity with the production site, but in my own use I can't see anything functioning in it. sandbox.ebay.com's signin hyperlink redirects to the production login 50% of the time, and the remainder of hyperlinks just redirect to production itself.
What I'd like to do is make my API calls, view my listings, buy those listings with a test user and observe the appropriate notifications being forwarded to my webhook URL, etc. however the sandbox front end seems to be entirely nonfunctional.
What am I missing here? Do I need to perform all these actions through the API? i.e. if I buy an item through the API I'll get a notification and that's as close as I can get to really testing this within the sandbox environment? Any guidance would be greatly appreciated here.
