Steps

  1. On each platform (Steam, PlayStation, Xbox, Apple, etc.), obtain the platform-specific auth token using the platform's SDK
  2. Call EOS_Connect_Login with an EOS_Connect_Credentials struct containing the token and the appropriate EOS_EExternalCredentialType (e.g. EOS_ECT_STEAM_SESSION_TICKET for Steam)
  3. If EOS_Connect_Login returns EOS_InvalidUser, a ContinuanceToken is provided — this means the external account is not yet linked; call EOS_Connect_CreateUser to create a new EOS Product User ID (PUID) from this token
  4. To link an additional platform to an existing PUID, call EOS_Connect_LinkAccount with the ContinuanceToken from the new platform's EOS_Connect_Login failure, passing the existing authenticated user's EOS_HConnect handle
  5. Store the PUID as your cross-platform player identifier; query it with EOS_Connect_GetProductUserId for all subsequent EOS service calls
