NRS e-invoicing, in a few lines of code.

One API and typed SDKs for Go, Node, Python, PHP and Java to issue, clear and manage invoices under Nigeria's e-invoicing mandate — SI and APP flows handled for you. We're finishing production hardening. Join the waitlist for early access.

+ Java

$ npm install @linkbridge/sdk

Already found @linkbridge/sdk on npm? You're early — and we'd love to have you. It's in active development and not yet production-ready. Add your details and we'll notify you the moment it is, with sandbox keys and docs.

What you'll get

Built the way developers expect.

We've been building this for a while — the SDKs are already public. The waitlist is for early, supported access as we finish hardening for production.

Typed SDKs in 5 languages

Node/TypeScript, Go, Python, PHP and Java — idiomatic clients, not thin HTTP wrappers.

IRN generation & clearance

Submit an invoice, get back a validated IRN and clearance status. The compliance detail is handled.

SI + APP flows

Built for both System Integrator and Access Point Provider roles under the NRS/FIRS model.

Webhooks & status

Subscribe to clearance and lifecycle events instead of polling. Know the moment an invoice clears.

Sandbox first

A full sandbox with test credentials so you can build and integrate long before you go live.

Idempotent by design

Safe retries with idempotency keys — submit confidently, even over flaky networks.

A taste of the API

Submit an invoice. Get an IRN.

No wrestling with raw endpoints, signing, or clearance state machines. Create the invoice, and the SDK returns a validated clearance reference and status.

Idiomatic clients, fully typed
Sandbox and production from the same code
Webhooks for clearance and lifecycle events

Illustrative — the final API is being finalised ahead of launch.

invoice.ts

import { LinkBridge } from "@linkbridge/sdk";

const lb = new LinkBridge({ apiKey: process.env.LB_API_KEY });

// Submit an invoice for NRS clearance
const invoice = await lb.invoices.create({
  supplier: { tin: "12345678-0001" },
  customer: { name: "Acme Ltd", tin: "87654321-0001" },
  lines: [
    { description: "Consulting", quantity: 1,
      unitPrice: 250_000, vatRate: 7.5 },
  ],
});

console.log(invoice.irn);      // → NRS clearance reference
console.log(invoice.status);   // → "cleared"

Be first in line when it goes live.
