Here’s an Apple shortcut that I believe will work and be easy for people to use, not sure though because I only have my own BMW account to test with. Could be other identifiers in there that I’d need to extract for it to work using someone else’s account.
I’ll put the link back once I fix it
It sends your MyBMW credential straight to the same API that the My Garage section uses, then returns to you some of the key data. Right now it just shows you status number, short description, VIN, and production date.
Use at your own risk though, since it authenticates each time you mash the button, you don’t want to get too trigger happy.
In the text elements inside the shortcut, just replace the login info with your own email/password, then each time you run it it’ll login as if you were using a web browser.
edit: the first time you run, it’ll ask you for access to both the endpoints it uses. The login api, and the garage api. Shouldn’t need to allow it any time after that.
