Asad - Estás buscando una solución de pago fiable para NIUBIZ y la tienes entre tus manos. He leído tu requerimiento con detalle y tengo claro cómo implementar una pasarela en PHP y MySQL, sin frameworks, que permita a los usuarios elegir sus deudas para pagar de forma segura y eficiente. Con más de 15 años de experiencia en desarrollo web completo, he integrado API de pagos, gestionado flujo de transacciones y construido arquitecturas escalables. Mi enfoque: 1) desarrollo modular en PHP puro (sin frameworks) para facilitar mantenimiento y seguridad; 2) creación de una interfaz clara para seleccionar deudas y procesar pagos a través de NIUBIZ; 3) gestión de estados de pago y logs para auditoría; 4) pruebas exhaustivas y medidas de seguridad (validaciones, sanitización, manejo de errores, cifrado de datos sensibles) y 5) acceso FTP y entrega con documentación y garantías de soporte. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Propongo un primer presupuesto de 180 USD y un plazo mínimo de 7 días hábiles, sujeto a confirmación tras revisar tus requisitos exactos y entorno. Con tu confirmación, entrego un plan diario de trabajo y milestones claros. ¿Qué esquema de API/endpoint de NIUBIZ se utilizará (página de pagos, notificaciones, y respuestas de estado), y qué métodos de prueba (sandbox vs producción) prefieres para validar la integración? Looking forwar

Hola, tengo experiencia sólida integrando pasarelas de pago, incluyendo NIUBIZ, trabajando directamente con PHP puro y MySQL sin frameworks. Mi enfoque sería implementar la conexión con la API de NIUBIZ manejando tokens de seguridad, sesiones de pago y la verificación de transacciones, mientras desarrollo la interfaz para que los usuarios seleccionen y paguen sus deudas de forma clara y segura. Estructuraré el código con buenas prácticas de seguridad como prepared statements y validación de datos para proteger cada transacción. Puedo comenzar de inmediato, me adapto sin problema al acceso FTP y mantengo comunicación constante para que estés al tanto del avance en cada etapa.

Hi, I can help implement the NIUBIZ payment gateway in your existing PHP and MySQL system without using any framework. The main technical problem is making sure the selected debts, payment request, NIUBIZ response, and database status updates stay fully synchronized and secure. I have experience with custom PHP, MySQL, REST/API integration, payment gateway workflows, transaction validation, callback handling, and server-side security. My solution would be to build a simple interface where users can select one or more debts, confirm the total amount, and proceed through the NIUBIZ payment process. I will also handle the backend logic for creating payment sessions, validating responses, preventing duplicate payments, and updating debt/payment records correctly in MySQL. Since access will be through FTP, I can work carefully within the existing folder structure and avoid unnecessary changes to the current system. The integration will be clean, secure, and compatible with your current PHP setup. Thanks, Hercules

Hola. Entiendo que necesitas integrar la pasarela de pagos de NIUBIZ en PHP y MySQL sin frameworks, con una interfaz simple para que el usuario seleccione sus deudas. He trabajado antes con APIs de pago y sistemas hechos a mano en PHP, así que puedo manejar la lógica y la seguridad que exige NIUBIZ. Puedo avanzar así: - Consumir los endpoints de NIUBIZ y validar tokens. - Crear la interfaz para seleccionar deudas y procesar pagos. - Manejar respuestas, logs y actualización en MySQL. - Probar todo directo en tu FTP. Podría tener una primera versión funcional en pocos días. ¿Tienes ya las credenciales de comercio de NIUBIZ en modo sandbox para empezar las pruebas? Saludos, Slavko
