API & Developers
Payment API for Multi-Provider Infrastructure
A marketing-level developer overview for CTOs, tech leads, and integration teams evaluating Exirom. Use one API or hosted payment page to connect supported providers, route payments, handle webhooks, and operate payment flows under your brand.
Developer Surface
Enough structure for technical due diligence before reading the docs.
This page does not replace API documentation. It gives technical buyers the product shape: integration options, webhook behavior, testing flow, and operational concepts.
One API for Multiple Providers
Integrate once and route supported providers and methods through Exirom instead of building separate operational logic for every PSP.
Hosted Payment Page
Use a hosted checkout flow when you want faster implementation, consistent status handling, and provider-enabled method display.
Webhooks
Receive transaction lifecycle events for approvals, declines, pending states, callbacks, reporting, and operational workflows.
Sandbox & Testing
Validate API calls, checkout behavior, status transitions, error paths, and provider-specific scenarios before production launch.
Idempotency
Design payment submissions and retries with duplicate protection, safer callback handling, and traceable request references.
Error Handling
Normalize provider responses into operationally useful states for routing, cascading, support, and reporting.
Data & Reporting
Keep transaction status, route attempts, provider references, fees, and status history available for operations.
Integration Flow
Discovery, provider setup, sandbox access, API testing, webhook validation, production readiness, and go-live support.
Typical Flow
From scoping to production traffic.
Confirm providers, methods, markets, checkout model, and compliance scope.
Set up sandbox credentials, routing assumptions, webhooks, and test scenarios.
Submit payment requests through API or hosted page and validate status transitions.
Test idempotency, callback handling, decline behavior, and reporting references.
Move to production with monitoring, provider health checks, and support workflow defined.
Walk Through the Integration
Bring your current flow, provider list, and webhook requirements. We will map how Exirom fits into the technical architecture.
