Unified Developer Integration Infrastructure
Connect your trading platform, checkout, or ERP system to PayFlow via official type-safe SDKs or direct REST API endpoints. Confidential credentials and complete sandbox tooling are provisioned upon merchant onboarding.
How Integration Executes Step-by-Step
From confidential credential provisioning to multi-rail channel selection and cryptographic webhook settlement.
Dual Confidential Credential Architecture
Both your API Key and Secret Key are strictly confidential server-side credentials. Neither is ever exposed to public frontends or browsers.
Identifies your merchant workspace. Configured strictly in secure server environment variables.

Connecting multiple payment rails across disparate banking APIs creates fragmentation, security risks, and reconciliation drift.
Fragmented Gateway APIs
Connecting to bank transfers, crypto swaps, and cash logistics usually requires juggling multiple vendor libraries with mismatched schemas.
Credential Security Exposure
Poor credential governance leaks privileged keys. Both API Key and Secret Key must remain confidential, server-side secrets.
Double-Charge Risks
Network timeouts and unhandled retries cause duplicate deposits and ledger discrepancies without strict idempotency locks.
Webhook Dropoff & Spoofing
Unsigned HTTP callbacks and dropped network retries leave merchant internal databases out of sync with bank balances.
Engineered for Mission-Critical Reliability
Enterprise integration specifications built for high-throughput brokers, prop desks, and international platforms.
Official Type-Safe SDKs
Native SDKs for TypeScript / Node.js, Python, PHP, and Go with complete type definitions and autocomplete.
Universal Direct REST API
Deterministic JSON over HTTPS with standard Bearer authentication, accessible from any language or custom ERP backend.
Confidential Key Governance
Both API Key and Secret Key are confidential server-side secrets with fine-grained capability scopes and IP whitelisting.
Atomic Idempotency Engine
Header-based idempotency keys ensure exact once-only financial execution, completely eliminating double transactions.
HMAC-SHA256 Signed Mesh
Every webhook notification is cryptographically hashed with timestamped replay protection and constant-time verification.
Isolated Sandbox Simulation
Test deposits, automated slip OCR matching, and webhook dispatches in a dedicated sandbox with zero financial risk.
Pre-Engineered Trading & CRM Integrations
Native connectors built for brokers, prop firms, e-commerce marketplaces, and custom financial back-offices.
MetaTrader 4 (MT4)
Direct Manager API integration injecting cleared trader margin in milliseconds with automated ledger reconciliation.
MetaTrader 5 (MT5)
Multi-currency balance syncing, instant equity credits, and programmatic trader withdrawal authorization.
Match-Trader
Embedded gateway connector enabling seamless trader deposits without third-party redirects.
Custom CRM & ERP
Bidirectional webhooks and real-time ledger streaming directly into Salesforce, HubSpot, or proprietary systems.
