SDKs & OpenAPI

An OpenAPI 3.1 spec for generating clients in any language, the raw REST API underneath, and a typed Node SDK on the way. Pick your altitude.

Coming soon

The @invoicejet/node package is not on npm yet; it ships at launch. Everything it wraps works today over the REST API with curl or any HTTP client, and the OpenAPI spec below can generate a typed client in the meantime.

OpenAPI

The full spec lives at /openapi.json. Feed it to openapi-generator, Kiota, Speakeasy, or your tool of choice to generate a client in any language.

Node: @invoicejet/node (coming soon)

Zero-dependency, fully typed, works in Node 18+ (and any runtime with fetch + WebCrypto). This is what it will look like:

Node

import { InvoiceJet, verifyWebhookSignature } from "@invoicejet/node";

const client = new InvoiceJet({ apiKey: process.env.INVOICEJET_API_KEY });

// extract and wait
const invoice = await client.invoices.extract({
  fileUrl: "https://example.com/invoices/june.pdf",
  wait: true,
});

// or fire-and-poll
const queued = await client.invoices.extract({ file: blob, fileName: "june.pdf" });
const done = await client.waitForCompletion(queued.id);

// list complete invoices ingested through the API
const { data } = await client.invoices.list({ status: "complete", source: "api" });

// key + quota check
const me = await client.me();

CLI & MCP (coming soon)

Also shipping at launch: the invoicejet CLI for scripts and pipelines, and the MCP server that gives Claude, Cursor, and any Model Context Protocol client invoice-extraction tools. Their docs preview what's coming.
