I need a robust mobile-recharge reselling API that works seamlessly across all operators. The goal is to let my platform trigger prepaid top-ups for Airtel, Jio, Vi, BSNL and any other carrier without manual intervention, while keeping every transaction traceable in real time. Core requirements • Full coverage of every Indian mobile operator; future addition of DTH or data-card endpoints should remain possible, but the first milestone is prepaid mobile only. • Auto-retry logic that attempts a failed recharge again within a configurable window and stops once the operator confirms success or a hard failure. • Real-time reporting: webhook or polling endpoints that push back status updates, balance changes and failure reasons so I can display them instantly on my dashboard. Deliverables 1. REST or JSON-RPC API specification with authentication flow. 2. Sandbox credentials for integration tests. 3. Sample code (PHP or Node preferred, but any language is fine). 4. Postman collection and a short setup guide. 5. Final hand-over after live recharge demos showing the auto-retry and real-time callbacks working for at least two operators. Acceptance criteria • A test recharge against each major operator completes successfully or fails gracefully and is retried automatically. • The reporting endpoint pushes status within 5 seconds of operator response. • Clear documentation lets a junior developer integrate in under one day. Please clarify which tech stack you will use on your side and how you secure the API keys.

Missing idempotency and race conditions cause duplicate topups or lost failures when an operators response arrives after a timeout. Ill enforce globally unique transaction IDs stored in Redis with atomic lock, combine exponential backoff retries and a webhook verifier that matches the ID before marking success. Last month I delivered a multicarrier recharge engine for five Indian operators, achieving 99.8% successful topups and cutting retryrelated failures by 42%; the system handled 10k transactions per day with subsecond status pushes. First 24hours Ill provision sandbox credentials, map each operators request/response schema and deploy the idempotent wrapper so we can run endtoend tests instantly. Quick question do the operators provide signed status callbacks (HMAC) or plain JSON? That determines the webhook security design. - Abdullah Z. (@redspector) | CEH | OSCP | AWS | Docker

Hello, Problem: Many recharge platforms experience failed transactions, delayed status updates, wallet synchronization issues, and unreliable API integrations, leading to poor user experience and increased support requests. Solution: I can integrate your preferred Mobile Recharge Reseller API into a secure platform with wallet management, recharge processing, transaction history, callback/webhook handling, commission management, user authentication, and an admin panel. My experience includes PHP, Laravel, Node.js, REST APIs, payment gateways, webhook integrations, wallet systems, and scalable backend development. Result: You will receive a stable, secure, and scalable recharge solution with real-time transaction updates, automated status synchronization, comprehensive reporting, and a foundation for future expansion into additional utility services. A few questions: • Which recharge provider or reseller API will be integrated (BBPS, Recharge API, Paysprint, Cyrus, Round Pay, etc.)? • Do you need only API integration, or a complete reseller portal with user, retailer, distributor, and admin panels? • Should the platform support additional services such as DTH, bill payments, AEPS, PAN, or money transfer? • Are webhook callbacks, wallet management, and commission distribution required? Thanks

Hello, I’m glad to have found your project, it aligns well with my experience building transactional backend APIs and event-driven systems. I would use Node.js (NestJS) or FastAPI with a queue-based architecture (Redis/BullMQ) to handle recharge requests, retries, and real-time status tracking. Each operator would be integrated through a provider-agnostic layer so Airtel, Jio, Vi, and BSNL can be supported consistently and extended later for DTH or data cards. Auto-retry would run through idempotent background jobs with configurable retry windows, and real-time updates would be delivered via secure webhooks with signed payloads. API keys and secrets would be protected using environment variables and encrypted storage, with request signing for added security. I’d like to go over a few points: Do you already have operator API providers, or should I integrate aggregators? Do you prefer webhooks only or a webhook + polling fallback? I’m confident I can deliver a reliable, scalable recharge API with retries, real-time reporting, and clean integration docs.

Hi, I hope you're doing well. I've delivered several backend API integrations that trigger telecom recharges and real-time callbacks. I built a recharge gateway that connected to an Indian aggregator, translating their SOAP/XML responses to JSON and handling operator quirks for Airtel and Jio; I used Node.js with Express and a Redis queue to handle retries for intermittent operator timeouts. I'd start by drafting the REST spec, then scaffold an Express service, Postgres for transactions, Redis for retry/backoff, HMAC-SHA256 auth for API keys and webhook signing, plus a simple PHP and Node sample client. Would be good to align on the retry window and the webhook payload shape, could we have a short chat to confirm the "retries within a configurable window" and the fields you need in the callback? Thank you, Valentin M.

Hi — you need a reliable prepaid-recharge reselling API across Airtel/Jio/Vi/BSNL with auto-retry and full transaction traceability. I build backend REST APIs and integrations, and the part that matters most here is exactly what you flagged: robustness. I'd put every operator behind one clean, uniform endpoint, add idempotent retry-on-failure with status reconciliation, and log every transaction with a traceable reference and real-time status so nothing is ever ambiguous — built so DTH/data-cards can be added later without rework. Which recharge aggregator/operator API do you have access to? That decides the integration. Happy to deliver one operator end-to-end as a first paid milestone so you see it working before we scale.
