• Implementation:

  await fetch(REWARD_URL, {
      method: "POST",
      headers: {
          apiKey: API_KEY,
          appId: APP_ID,
          "Content-Type": "application/json",
      },
      body: JSON.stringify({
          sessionId: currentGameId,
          userRewardedList: [{ userId: winner, amount }], // `amount`: Total bet amount in the game
      }),
  });

• Example Response:

  {
      "message": "Successfully!",
      "sendSuccessList": [userId],
      "sendFailList": []
  }

Notes

• Ensure that REWARD_URL, API_KEY, and APP_ID are correctly set up in the .env file.
• Always validate eventData before sending it to avoid runtime issues.
• The winner’s userId and the amount must align with the game's session data for successful reward distribution.
