GAPI.LOL API throwing unknown error while opening Game - php

Question

I am integrating gapi.lol API into a website and the examples are in core PHP and so I had to rewrite them to Laravel because it is the framework the website is using. The API has no support team and so there is no one I can ask a question when need be. I did everything as instructed, however, the problem comes when opening a single game, it throws an unknown error!
The following is the guidance on their website on how to integrate the API.
Importand when a player wins EGT jackpot, Our api server sends writeBet api call with game ID 2500 and your api server should answer with success message
Global jackpot will sends the id of the game player playing.
EXAMPLE
return $apiresult = array(
"status" => "success",
"error" => '',
"login" => ExampleAccount,
"balance" => PlayerBalance,
);
#1 Create users table (you can use your existing table)
-- ----------------------------
-- Table structure for users
-- ----------------------------
DROP TABLE IF EXISTS `users`;
CREATE TABLE `users` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`score` bigint(20) DEFAULT '0',
`callback_key` varchar(64) CHARACTER SET utf8 DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `ext` (`callback_key`) USING BTREE
) ENGINE=MyISAM AUTO_INCREMENT=2 DEFAULT CHARSET=latin1;
#2 Create table user_bets (save bet/wins)
-- ----------------------------
-- Table structure for user_bets
-- ----------------------------
DROP TABLE IF EXISTS `user_bets`;
CREATE TABLE `user_bets` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`in` bigint(20) DEFAULT '0',
`out` bigint(20) DEFAULT '0',
`user_id` bigint(20) DEFAULT NULL,
`date` datetime DEFAULT '1970-01-01 00:00:01',
`game_id` bigint(20) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=49 DEFAULT CHARSET=latin1;
#3 Create wallet
This is php example you can use any language you want.
if you use your own table do not forget to change the fields on mysql querys
header('Access-Control-Allow-Headers: *'); // This is only for test your wallet
header('Access-Control-Allow-Origin: *'); // This is only for test your wallet
header('Access-Control-Allow-Methods: POST'); // This is only for test your wallet
header('Access-Control-Max-Age: 1000'); // This is only for test your wallet

I am handling it in a way that I list all the games from the API on the home page when someone clicks on any single game, I generate the game URL in the getURL method in wallets controller, the redirect the user to that page. It works well but when someone opens the game, it throws an error in the process of opening.
