how do I get a test user's user ID?
I'm trying to test IAP using this method:
https://developers.meta.com/horizon/documentation/unity/ps-iap-s2s/#verify
I think I'm getting close, but when I use the curl command with "user_id=[test username]" it complains that I'm not using a valid user id.
{"error":{"message":"Parameter user_id: invalid user id: [test user's username]" ...So how can I get the game-specific user id for a test user? I don't see any options to do so on the developer portal, and I haven't had any luck googling it. I would expect that id to be on the test users page on the developer portal for this game, but it's not.
