FreeKassa API Integration in Laravel Casino

I'm seeking a seasoned developer to integrate the FreeKassa payment system into my Laravel-based online casino. Key requirements include: - Configuring the reception of payments and payouts via the FreeKassa API. - Implementing webhook handling for automatic payment status updates. - Ensuring API request security (signature, data tampering protection). - Incorporating functionality for user balance top-ups and withdrawals. - Conducting integration testing and troubleshooting any potential errors. The server is Ubuntu/Debian, so familiarity with this OS is a plus. Prior experience with the FreeKassa API and Laravel is mandatory. The ideal candidate should also possess strong problem-solving skills and a keen attention to detail to ensure a seamless user experience.
