Developer Platform

Developer-First API Keys

aivvrellex gives engineering teams a purpose-built key management system that enforces least-privilege access, scales to millions of requests per day, and integrates in minutes — not weeks.

  • Scoped Permissions

    Grant precise access with granular OAuth-style scopes — cards, payments, webhooks, and reporting, fully isolated per key.

  • Webhook Events

    Subscribe to real-time event streams — card issuance, payment settlement, fraud alerts — delivered with signed payloads and retries.

  • Sandbox Testing Environment

    Mirror production APIs in an isolated sandbox with synthetic card data, simulated declines, and full webhook replay — no real funds involved.

  • Versioned REST Endpoints

    Stable, versioned API surfaces (v1, v2) with long-term support guarantees. Deprecation notices issued at least 12 months in advance.

  • SDKs in Python, Node & Go

    Officially maintained client libraries with full type safety, automatic retries, idempotency helpers, and changelog-driven releases on GitHub.

"aivvrellex transformed how our treasury team operates across 14 countries. The card controls are surgical — we can set spend limits, merchant categories, and FX rules per card in seconds. Our finance directors used to spend hours reconciling; now it's real-time. This is the infrastructure global finance deserved a decade ago."
