Paynex is designed for API-level integration with banking, compliance, and payout infrastructure. This section covers our integration model, environments, event system, and partner onboarding process for technical counterparts.
Paynex exposes RESTful APIs for payout orchestration, account management, and compliance workflow integration. API authentication uses short-lived tokens with scoped permissions. All endpoints follow predictable request/response contracts with structured error codes.
Sandbox and production are isolated environments with separate credentials and data. Sandbox replicates production API behavior, compliance flow gating, and payout rail responses — enabling full integration testing without capital movement or live data exposure.
Paynex uses a webhook-based event model for asynchronous state changes. Events cover payout lifecycle (initiated, processing, settled, failed), compliance status transitions, and account provisioning confirmations. All payloads are signed and versioned.
Structured endpoints for payout initiation, corridor routing, status polling, and settlement confirmation. Corridor-specific parameters, recipient validation, and fee transparency are built into the payout request model.
Structured request/response patterns designed for fast integration and reliable payout orchestration.
// Example: Initiate a Payout
POST /v1/payouts
{
"corridor": "NG",
"amount": 50000,
"currency": "NGN",
"recipient": {
"name": "John Doe",
"bank_code": "044",
"account_number": "0123456789"
},
"reference": "payout_abc123",
"metadata": {
"invoice_id": "INV-2024-001"
}
}A structured five-step integration process designed for speed and compliance.
Structured kickoff to define integration scope, corridor priorities, API surface, compliance handoff points, and partner infrastructure dependencies.
Dedicated sandbox environment provisioned with API credentials, webhook endpoints, and test corridor configurations for full integration validation.
Build and test against Paynex APIs. Validate compliance workflow gating, account provisioning responses, payout initiation, and event delivery.
Formal review by compliance partner and infrastructure stakeholders to confirm regulatory alignment and operational readiness before production access.
Staged production go-live with volume controls, monitoring, and a defined escalation path. Full production access granted after initial validation period.
