sevdesk plugin

Use sevdesk through Corsair: one client, typed API calls. This plugin uses the API token as a raw 32-character hexadecimal Authorization header. Calls use JSON only. X-Version is optional through the per-call resourceVersion input or plugin-level fallback. List responses use the documented objects array and optional total count; list routes document limit (1–1000), offset, and countAll pagination. For Update 2.0 accounting, prefer taxRule and verify allowed tax rates through ReceiptGuidance. Enshrinement is legally irreversible. Webhook receiving is excluded because the official OpenAPI inventory defines no callback/webhook routes. Multipart voucher upload and invoice XML retrieval are excluded from this JSON-only plugin. What you get:

Setup

Install

npm install corsair @corsair-dev/sevdesk better-sqlite3
npm install --save-dev @types/better-sqlite3

yarn add corsair @corsair-dev/sevdesk better-sqlite3
yarn add --dev @types/better-sqlite3

pnpm install corsair @corsair-dev/sevdesk better-sqlite3
pnpm install --save-dev @types/better-sqlite3

bun add corsair @corsair-dev/sevdesk better-sqlite3
bun add --dev @types/better-sqlite3

Add the plugin

corsair.ts

import Database from 'better-sqlite3';
import { createCorsair } from 'corsair';
import { sevdesk } from '@corsair-dev/sevdesk';

export const corsair = createCorsair({
	plugins: [
		sevdesk(),
	],
	database: new Database('corsair.db'),
	kek: process.env.CORSAIR_KEK!,
	multiTenancy: true,
	hub: {
		projectApiKey: process.env.CORSAIR_API_KEY!,
		signingSecret: process.env.CORSAIR_SIGNING_SECRET!,
	},
});

With multiTenancy: true, scope calls with corsair.withTenant(id). See Quick start for KEK + Hub keys, and Multi-tenancy for account isolation.

Choose authentication

API Key (Recommended)

Store the sevdesk API key before the first call: pnpm corsair setup --plugin=sevdesk --tenant=acme api_key=<your-key> (leave out --tenant without multiTenancy), or pass it as key in the plugin options. With Hub, each tenant enters their own key on the connect page. See API key auth.

Connect a tenant

Mint a connect link and send the tenant to it. Hub hosts the page and delivers the result to your app — see Connect / OAuth.

const { connectUrl } = await corsair.manage.connect.createLink({
	plugin: 'sevdesk',
	tenantId: 'acme',
});
// redirect the user's browser to connectUrl

Example API calls

contact.getContacts

const tenant = corsair.withTenant('acme');
await tenant.sevdesk.api.contact.getContacts({});

contact.createContact

const tenant = corsair.withTenant('acme');
await tenant.sevdesk.api.contact.createContact({
	body: {
		name: 'Corsair sample contact',
		category: { id: 3, objectName: 'Category' },
	},
});
