You can now add a game to Gamosy without sharing any API key. Store page verification generates a one-time proof token - gamosy- plus 16 characters - and you place it on your game's Steam store page: as plain text in the About This Game section, or as ?gamosy=TOKEN on the Website link. Gamosy reads the public page, finds the token, and the game lands in your library with full store data. No key, no login, no access to your Steamworks account.
Two Methods, Side by Side
The Developer → Games screen now shows both paths with a comparison table: the Publisher API Key for whole-catalog import with automatic resync, and store page verification for adding one game with zero credentials. Both unlock the same product - campaigns, encrypted key storage, analytics. Studios with a published gmsy.me bio page get a ready-made verification URL to set as their store page Website, which doubles as a landing page with socials and a live wishlist widget.
Opt-In Wishlist Import
Studios connected with a Publisher API Key that carries the Sales Data permission can enable automatic wishlist import: daily wishlist activity - additions, deletions, purchases - flows into your game's analytics without manual entry. It is strictly opt-in and validated before anything is saved.
