FAQ

Welke games ondersteunt de Inventory API?

Elke Steam-communitygame met openbare inventories — CS2, Dota 2, Rust, TF2, Steam zelf, en meer. Geef de appId van de game door.

Hoe doe ik een batch-fetch?

POST een lijst SteamIDs naar /steam/api/inventory/batch (max 100 per call). De respons is gekeyd op SteamID.

Moet ik de rate limits van Steam beheren?
