Rapid, compliant integration of payme's payments, transactions and reconciliation into your backend

We provide protocol analysis (including necessary reverse engineering scope) based on public/authorized interfaces, runnable API source code, automated tests, and interface documentation, covering QR payments, card-to-card, bill payments, subscriptions and Payme Plus scenarios.

QR / payme go integration — Merchant QR verification, transaction callbacks (webhook), settlement confirmation and refund flow.
Card-to-card & gateway — Card-to-card top-ups and withdrawals via Visa / Hum o / Uzcard, with PCI 3DS processing guidance.
Transactions & ledger API — Monthly and per-transaction extraction, export to CSV/Excel/PDF, with time-window filters and spend analysis categorization.
Subscriptions & Payme Plus — Recurring charges, quotas and trials management, with user authorization and unsubscribe callbacks.

Deliverables & sample outputs

  • Runnable backend code: API services (Python/Node.js/Go optional), with Docker templates
  • Webhook and asynchronous notification handling examples
  • Automated tests, API mockors and deployment guides

{
  "account_id": "user_abc123",
  "from": "2025-10-01",
  "to": "2025-10-20",
  "format": "json"  // or 'csv'|'xlsx'
}

  "to": "2025-10-20",
  "page": 1,
  "page_size": 50
}

}

Advanced module

Optional modules: NFC event parsing, virtual card token sync, server-side Tap-to-Pay events callbacks, dispute automation and adapters for third-party clearing/gateways.

API Integration Guidelines (Quick Start)

  1. Provide the target use case (e.g., merchant acquiring, balance export, subscription).
  2. We perform protocol and authorization analysis (2-5 business days) with necessary reverse engineering scope and compliance boundaries.
  3. Deliver runnable API code and OpenAPI docs with example SDKs (typically 3-10 business days).
  4. Assist with deployment, integration testing and one production readiness audit (optional).

Authentication & Security Advice

  • Access tokens (Bearer / JWT) or HMAC signatures; short lifetimes with refresh
  • Webhooks with signatures and time-window validation
  • PCI DSS compliance: avoid storing card numbers in your systems; use tokenization or gateway hosting
  • Rate limits, IP whitelisting and suspicious transaction alerts
