comFac's REST API gives developers everything needed to embed cross-border payment capabilities into any application — with clean documentation, SDKs, and a sandbox that mirrors production.
Payment infrastructure is one of the most complex and critical pieces of any global application. A poorly integrated payment system causes failed transactions, unhappy users, and compliance headaches. comFac was designed API-first — meaning every feature available in the dashboard is also available via API, with no exceptions.
The REST API follows industry-standard conventions with predictable resource-oriented URLs, JSON request and response bodies, and standard HTTP status codes. Comprehensive documentation with real code examples in seven programming languages — JavaScript, Python, PHP, Ruby, Go, Java, and .NET — means your team isn't starting from scratch. Most integrations go from sandbox to production in under two weeks.
Our sandbox environment is a complete replica of production — same data models, same response formats, same webhook events — but using simulated transactions. You can test edge cases, simulate failures, and validate your integration thoroughly before going live. And with a 99.9% uptime SLA and sub-50ms average API response times, comFac is built to be the reliable backbone of your platform.
POST /v1/payments HTTP/1.1 Host: api.comfac.io Authorization: Bearer sk_live_xxxxxxxxxxxx Content-Type: application/json { "amount": 50000, "currency": "USD", "destination_currency": "JPY", "recipient": { "name": "Tanaka Trading Co.", "account_number": "1234567890", "routing_code": "MUFGJPJT" }, "reference": "INV-2025-4872" }
From first API call to enterprise-scale production, comFac gives developers the tools they need to ship fast and scale confidently.
Our streamlined onboarding process gets developers from first call to live payments faster than any other global payment API.
