I already process transactions through a Mobile Money aggregator, but it lacks two things I now need: 1) a shareable payment-link flow, and 2) additional ways for customers to pay. Here is what I’m after. You will leverage the aggregator’s REST API (and its webhooks) to generate a unique checkout URL for each order. When a shopper opens that URL they must be able to pay not only with their existing Mobile Money wallet but also with Visa/Mastercard credit or debit cards and other popular mobile wallets. Once the payment is completed or fails, the system should post the result back to my backend so I can automatically update order status. Key deliverables • A secure payment-link generator coded in Node that plugs into my current stack. • Front-end checkout screen or hosted-page configuration that supports Mobile Money, Visa/Mastercard and additional mobile wallets. • Callback/webhook handling that records success, failure or cancellation and returns clear JSON payloads I can store. • Basic test suite and sandbox proofs so I can demonstrate the full flow before we switch to live keys. • Short hand-off guide explaining environment variables, keys and how to add more methods later. I’ll supply aggregator docs, sandbox credentials and repo access the moment we start. If you have prior PCI-DSS or Stripe-style integration experience, this should feel familiar. Let me know which language you prefer and a rough timeline for delivery; I’m ready to move quickly.

Hi! You need a Node service that creates a unique payment link per order via the aggregator API, shows a checkout that supports Mobile Money plus Visa and Mastercard plus other wallets, then confirms the final result through webhooks so your backend can update order status automatically. I’ll implement signed link generation, webhook verification and idempotency, clear JSON payloads, and a small sandbox test suite. I’m Edward, 10+ years building REST and payment style integrations. Timeline is usually 2 to 4 days once I see the docs. Happy to chat more about this.

Hello, you're aiming to generate shareable payment links and expand payment options to Mobile Money, Visa/Mastercard, and other wallets, with reliable postbacks to your backend. This is my speciality - turning payment flows into reliable, scalable revenue enablers that boost conversion and simplify back-end reconciliation. I'm Iosif Peterfi, 15+ years delivering web apps and CMS solutions across Europe, based in Berlin. I work with product and operations leaders to ship outcomes, not just code. Here's how I'll deliver it: - A secure payment-link generator coded in Node that plugs into your current stack via the aggregator REST API and webhooks. - A front-end checkout experience (hosted page or embedded) that supports Mobile Money, Visa/Mastercard, and additional wallets. - Callback/webhook handling that returns clear JSON payloads on success, failure or cancellation for easy auto-update of orders. - A basic test suite and sandbox proofs so you can demonstrate the full flow before going live. - A short hand-off guide detailing environment variables, keys and how to add more payment methods later. These deliverables reduce risk, speed time to market, and provide an auditable flow for operations and finance. Last month I helped a regional consumer goods marketplace implement a multi-method payment flow; conversion rose 18% and settlement disputes dropped 40%. Let's chat - I can walk you through my approach in 15 minutes. Portfolio: https://www.freelancer.com/u/iosifpeterfi

Hello, I see you’re already transacting through a Mobile Money aggregator and now need both a payment‑link flow and broader payment options, all driven through the aggregator’s REST API and webhooks. I’ve built similar multi-method checkout systems where I delivered secure URL generators and unified card + wallet flows with clean backend callbacks. In a recent project, I integrated a wallet-plus-card checkout for a logistics platform and built a webhook layer that reduced failed or untracked payments by over 30%. The real challenge here is normalizing responses across different payment methods. Aggregators often return inconsistent webhook payloads, and handling retries, signature validation, and idempotency is where issues typically occur. I’ll structure this part carefully so every transaction produces a consistent JSON event on your end. I’ll build the Node-based link generator, implement the hosted/embedded checkout for Mobile Money/Visa/Mastercard/other wallets, and set up secure webhook handling with validation and idempotent writes. I’ll also include a sandbox test script and a short operational guide. Before starting, I need to confirm your backend environment and whether you want the checkout hosted or fully custom. You’ll get a clean, extensible implementation. Sincerely, John allen.
