During March 2025, Matin Ghafourian migrated the MatinSMS gateway in the wp-sms/wp-sms repository from a SOAP-based client to a RESTful API, focusing on backend development and API integration using PHP. He refactored core SMS operations, such as SendSMS and GetCredit, to utilize HTTP requests with JSON responses, which improved both reliability and performance for transactional messaging. Matin also enhanced error handling and configuration management, ensuring smoother operation and easier maintenance. By updating tariff and trial data to align with the new API, he addressed accurate billing and service consistency, demonstrating a thorough approach to plugin development and system modernization.
