ดาวน์โหลด EOS SDK (C#) 1.19.2.1

INTERFACES

Ecom
- Update: Support for Apple’s Core Technology Commission (CTC) tokens in third-party games on the Epic Games Store Mobile. When you call EOS_Ecom_Checkout, the EOS SDK generates the token and passes it to Epic Games servers. You can later retrieve the tokens and their associated checkout information from Epic Games servers through the new Ecom Web API endpoints. This token is also available locally through EOS SDK API callback info, if you need it on a client. You are responsible for reporting CTC tokens to Apple for your app’s in-app purchases. For more information, see the documentation: Report CTC Tokens on iOS.
- New: EOS_Ecom_CheckoutCallbackInfo returns the CTC token to your game in the following new fields:
- CTCToken: the CTC token.
- CTCTokenType: the type of CTC token. This is APPLE_MARKETPLACE_CTC or NULL when CTCToken is NULL.
- CatalogRegion: the eligibility region that Apple reports for the device. This is not the storefront or pricing region of the purchase. This is NULL when CTCToken is NULL.
- New: The EOS SDK now returns EOS_EResult::EOS_Ecom_CheckoutCTCUnavailable when the EOS SDK is configured to block the purchase. This is in case the CTC token is required and cannot be obtained from Apple.

Anti-Cheat
- New: Added EOS_AntiCheatClient_GetSystemRequirementStatus to the Anti-Cheat Client Interface. Use this function to check which security requirements the player and their local machine satisfy, such as Secure Boot and a Trusted Platform Module (TPM). For more information on these requirements, see the Anti-Cheat Interfaces documentation.
- The function returns the status as an EOS_EAntiCheatClientSystemRequirementStatus value: NotMet, MetWithWarning, or FullyMet.
- When the status is NotMet or MetWithWarning, the function also returns an explanation in OutReason that you can display to the player, so they have the information they need to proceed. The anti-cheat client provides these messages and they are localized, so your game does not need to write or translate them.
- Use the new EOS_AntiCheatClient_GetSystemRequirementStatusOptions struct to pass the system configuration to check in ClientSystemConfig, and the size of your OutReason buffer in OutReasonLength.
- These client values are intended for UI and UX purposes only. To enforce them securely, server verification based on remote attestation is available as part of the paid anti-cheat advanced services.
- Bug fix: Hardened the Anti-Cheat server against malformed or modified client network messages.
- Bug fix: Fixed an issue where throttling of EOS_AntiCheatServer_LogPlayerTick calls worked only intermittently. Call throttling now uses a time-window approach.

Authentication
- Breaking change: From 2026-oct-01, Epic Account Services (EAS) access tokens increase in size, up to a limit of 8 KB.
Your game can retrieve an EAS access token from the Auth Web API token endpoint or through the EOS SDK’s Auth Interface.
As per OAuth 2.0 best practices (RFC 6749), your game should never assume a fixed token size. Before 2026-oct-01, check that your game
