Integration with Fondy

We provide a straightforward technical integration of Fondy with your website, marketplace, or mobile app. Our focus is implementation and configuration according to the official API and guidelines.

The scope includes account setup, API methods wiring, webhooks/callbacks, test transactions in sandbox, and production launch with handover documents.

We document the flow (sequence diagrams, states), prepare a credentials map, and provide a runbook for your team. If your infrastructure requires queues, retries, or idempotency, we add them within the integration boundary.

All work is performed according to Fondy requirements and your environment constraints.

  • Account & keys configuration
  • API endpoints and payment flow
  • Webhooks/callbacks and status mapping
  • Sandbox tests and production switch
  • Logs and basic alerts
  • Documentation and handover
