SDK & Sandbox
Full-featured test environment with realistic ledger states, simulated payment rails, and Postman collections. Build and test every scenario before your first production call.
API Documentation
Complete REST API reference covering accounts, payments, FX, webhooks, Open Banking, and approval controls. Clear schemas, versioned endpoints, and working examples throughout.
REST API
Standard REST with JSON payloads, idempotency keys, granular OAuth 2.0 scopes, and webhook subscriptions for real-time event delivery across every operation.
Integration paths
From sandbox to your first API call in minutes
Get a full sandbox environment, working Postman collections, and quickstart guides for every use case. No production credentials required to start.
Sandbox access from day one
A full sandbox with realistic ledger states, simulated payment rails, and live webhook delivery. Build and test every production scenario in a safe environment before going live.
Postman collections included
Pre-built Postman collections covering every endpoint, authentication flow, and webhook scenario. Import and start making calls in seconds.
Quickstart guides by use case
Integration paths for payments, accounts, FX, and webhooks — each with working code examples and clear next steps.
Documentation
Docs that help developers ship faster
Clear schemas, working examples, and full endpoint coverage for every operation. The API reference is built for teams who need to understand the integration surface quickly — not wade through marketing copy. Every endpoint includes authentication context, request and response examples, and error codes.
Sandbox environment
Build and test every scenario before going live
A full-featured test environment with realistic ledger states, simulated payment rails, and live webhook delivery. Every production scenario is replicable in sandbox — including edge cases, failures, and multi-step approval flows. No production risk, no production credentials required.
Authentication
OAuth 2.0 with granular scopes and per-resource access control
Token-based authentication for server-to-server integrations, user-delegated access for platform flows, and API keys for machine access. OAuth 2.0 scopes map to individual resources so you grant only what your integration needs — nothing more, nothing wider.
Integration philosophy
One integration surface. Every financial capability.
The Xace API is not a feature subset. It is the full operational layer — accounts, payments, FX, webhooks, controls, and Open Banking — accessible from a single, versioned REST interface.
Every API call carries compliance context, operates on a proven regulated infrastructure, and is backed by a technical team engaged from your first architecture review through to go-live and beyond.
