تطوير نظام دفع مخصص وتكامل API مع Uscreen

@kamran2012

Hello, I'm a backend developer fluent in Arabic with extensive experience in custom payment systems and API integrations. I recently worked on a subscription-based platform that required integration with a regional payment gateway, similar to your needs with Uscreen. For your project, I can integrate a suitable payment gateway for Kuwait that handles recurring subscriptions, Visa, and MasterCard. I recommend using Tap Payments or MyFatoorah due to their regional support and robust subscription management features. I'll ensure security with tokenized payments and PCI compliance, and implement a custom checkout system to manage subscriptions, including renewals and cancellations. For Uscreen API integration, I'll utilize the Publisher API for customer access management, ensuring seamless subscription logic and webhook verification for payment events. I'll prioritize security by not storing card data and using secure hosting with SSL. Questions: 1. Have you decided on a specific payment gateway, or do you need assistance in selecting one? 2. Is there a preferred timeline for project completion? Looking forward to discussing further how I can contribute to your project's success. Thanks and best regards, Kamran

I can handle this end-to-end. I have experience building secure payment flows and API-based integrations and can implement the full custom checkout and subscription logic exactly as outlined. I will cover: Payment gateway integration (cards, recurring subscriptions, tokenized/PCI-compliant flows) Custom checkout screen with clean API-driven logic User access APIs (create, update, revoke access) Webhooks handling for subscription states (active, past due, canceled, etc.) Proper logging, error handling, and production-ready security setup The solution will be built using a clean REST-based architecture (Node.js / Python / PHP as preferred) and delivered with clear documentation so it’s easy to maintain or extend. I’m ready to start immediately. Once we begin, please share: The payment provider credentials (sandbox first) API specs or expected request/response formats Any existing backend or database structure (if available) We can align on timeline and milestones right after kickoff.

Hi I'm from morocco, I’m a Data Scientist / AI Engineer and I can deliver your [Project Name] end-to-end: data ingestion → modeling/LLM layer → API → deployment. I’ve built production ETL pipelines (CSV/PDF/HL7/FHIR), ML/DL scoring, anomaly detection, and LLM solutions including embeddings-based ranking and LangChain RAG bots that answer with citations. What you can expect: • Clear architecture + scalable database design (PostgreSQL + pgvector / Redis / Elasticsearch) • LLM/RAG pipeline (indexing, retrieval, evaluation) + secure APIs (Django/FastAPI) • Frequent Git updates, clean code, and staging + production deployment (Docker/CI/CD) To start quickly, share: data sources (format/volume), target outputs (UI/API), constraints (latency/cost), and success criteria. I’ll reply with a short technical plan + milestones. Best regards, Amine

Hello there, I am an Arabic-speaking backend developer with expertise in building custom payment systems and API integrations. I can develop a tailored checkout system that connects with Uscreen for subscription management, ensuring it works with a payment gateway suitable for Kuwait and the Gulf, supporting Visa & MasterCard, recurring subscriptions, and tokenized payments. I will integrate Uscreen's Publisher API for managing customer access and handle subscription states with precise Webhook management. Security is paramount; I will ensure PCI compliance and prevent card data storage, with robust error handling and logging. Questions: • Could you specify any preferred payment gateways for the Gulf region that support recurring payments? • Is there a specific timeline you envision for going live? Having previously worked with Uscreen API and similar platforms, I am familiar with subscription logic and can provide a secure, scalable solution with complete technical documentation and launch support. Looking forward to discussing how I can contribute to your project in detail. Thanks and best regards, Faizan

مرحبًا، لإنشاء نظام اشتراكات شهري موثوق بدون Stripe، النقطة الأكثر حساسية هي إدارة حالات الاشتراك وربطها بشكل صارم بصلاحيات Uscreen. سأتولى ذلك عبر بناء Checkout مخصص يدعم بوابة دفع متوافقة مع الكويت، مع Webhooks موقعة تتحكم بدقة في تفعيل وإلغاء الوصول عبر Uscreen API. نفذت أنظمة اشتراك متكررة بدون Stripe لأسواق خليجية، حيث كانت أكثر نقاط الفشل شيوعًا هي التجديد الفاشل وسحب الصلاحيات المتأخر، لذلك أتعامل مع هذه الحالات بمنطق فوري وآمن. أسلوبي مباشر. أبدأ باختيار بوابة الدفع المناسبة، ثم أبني منطق الاشتراك و-Webhooks، وأكمل بربط Uscreen وإعداد بيئة Production مع توثيق واضح. جاهز للبدء بتثبيت بوابة الدفع وتعريف حالات الاشتراك كأساس صحيح من اليوم الأول. هل لديكم بوابة دفع مفضلة حاليًا أم تريدون مني اقتراح الخيار الأنسب للكويت؟

@extreamcode

@nicolasalexandro

I already see a clean way to execute this. I specialize in backend development with secure payment integrations, custom checkout flows, and third‑party API connections. Your need for a custom payment system that works smoothly with Uscreen and supports Arabic while keeping performance and security tight align perfectly with my skills. I’m confident I can deliver a robust, well-documented backend that your team can easily maintain and extend. You want a clean and professional checkout experience tailored to your business rules, fully in Arabic if needed, while syncing users, subscriptions, and payments reliably with Uscreen’s API. This means stable webhooks, clear error handling, and a structure that is ready for future gateways or pricing models without rewriting everything. I’d focus on designing a clear payment flow (initiation, confirmation, webhook handling, and subscription activation), then mapping it carefully to Uscreen’s API endpoints. I would implement secure token handling, detailed logging for debugging, and a modular architecture so you can plug in additional payment methods later with minimal changes. Quick question before I suggest an approach: Do you already have a preferred payment gateway for the custom checkout (e.g., local bank, Stripe, Tap, Payfort), or should I propose one that best fits your target region and currency setup? Lets chat more about your project, worst case you walk away with a free strategy session Regards

I NEVER USE AI FOR BIDDING! تبحث عن مطور Backend محترف يجيد العربية لربط نظام دفع مخصص مع Uscreen ودعم اشتراكات متكررة في الخليج. لديّ خبرة عملية واضحة في بناء أنظمة اشتراكات مع بوابات دفع تدعم الخليج، وتكامل APIات REST وWebhooks بنجاح. Looking forward to discussing more details. خبرتي: بوابات الدفع: Tap Payments, MyFatoorah, PayTabs (الخليج – دعم اشتراكات متكررة، Tokenized, PCI) Backend: Node.js, PHP, Python APIs: Webhooks, RESTful integration, Membership/SaaS systems Uscreen: خبرة مباشرة في تكامل Uscreen Publisher API وتحكم صلاحيات الدخول Security: استضافة آمنة، SSL، عدم تخزين البطاقات (اعتماد Vault/payment gateway)، Logging, Error Handling الإجابات: ١. بناء نظام اشتراكات شهرية بدون Stripe يعتمد على ربط Gateway مثل Tap أو MyFatoorah تدعم recurring billing. بوابة الدفع تبعث Webhook عند كل عملية خصم أو فشل، أقوم باستقبال الـWebhook، أتحقق من صحته، وأحدّث حالة الاشتراك وتفعيل/إلغاء الصلاحية فوراً. ٢. شغلت على Tap, MyFatoorah, PayTabs في الكويت والسعودية والإمارات، جميعها تدعم recurring subscriptions وPayment Tokenization. ٣. عملت مع Uscreen API لمنصة عضويات تعليمية (create user/access, revoke on cancellation/renewal) وأيضاً مع Memberful وTeachable APIs. ٤. صلاحية الدخول تسحب فور استقبال Webhook بفشل التجديد، يتم التنفيذ آنياً عن طريق DELETE /customers/{customer_id}/accesses عبر API. ٥. أمان الدفع مضمون بالاعتماد الكامل على Gateway في معالجة البطاقات (Tokenization)، وعدم تخزين بيانات الدفع في السيرفر إطلاقاً. ٦. تحقق صحة Webhook عن طريق توقيعات HMAC/Header verification من البوابة ومطابقتها مع الـsecret في السيرفر. ٧. أنصح بـ Tap Payments: لأنها تدعم الاشتراكات الشهرية، متوفرة في الكويت والخليج، PCI DSS، دعم ممتاز، API وثائقية قوية. ٨. نعم أستطيع الشرح والتواصل الكامل بالعربية.

@MSaadJaved

Hi Fawaz, Let's create a PCI-compliant custom checkout integrated with Uscreen and a GCC-ready recurring payments gateway I see the core constraint: Stripe isn’t available in Kuwait, so you need tokenized recurring billing, reliable webhooks, and immediate Uscreen access control. I’ve implemented subscription platforms for GCC markets using Tap, HyperPay and PayTabs, built webhook-driven retry logic and tokenized checkouts. My strength is fast, clear execution focused on delivering production-ready outcomes. I’m responsive, timezone-flexible, and open to your budget and timeline. My approach is straightforward: PCI-safe tokenization, signed webhook verification, retry schedules, and state sync with Uscreen Publisher API to create/renew/cancel accesses plus secure hosting and logging. I deliver clean, documented code and launch support, and I can explain the design and progress in Arabic. Available to chat and clarify technical details. Best regards, Saad
