  Yuki integration via Apideck's Accounting unified API — same methods work across every connector in Accounting, switch by changing `serviceId`. Use when the user wants to read, write, or reconcile invoices, bills, payments, ledger accounts, and journal entries in Yuki. Routes through Apideck with serviceId "yuki".

# Yuki (via Apideck)

Access Yuki through Apideck's **Accounting** unified API — one of 34 Accounting connectors that share the same method surface. Code you write here ports to Access Financials, Acumatica, banqUP and 30 other Accounting connectors by changing a single `serviceId` string. Apideck handles auth, pagination, rate limiting, and retries so you don't write per-tenant Yuki plumbing.

> **Beta connector.** Yuki is currently in beta on Apideck. Expect partial resource coverage and occasional mapping gaps. Always verify coverage (see below) and fall back to the Proxy API for unsupported operations.

## Quick facts

- **Apideck serviceId:** `yuki`
- **Unified API:** Accounting
- **Auth type:** apiKey
- **Status:** beta
- **Apideck setup guide:** [Connection guide](https://developers.apideck.com/connectors/yuki/docs/consumer+connection)
- **Gotchas:** [page](https://developers.apideck.com/apis/accounting/yuki/gotchas)
- **Yuki docs:** https://api.yukiworks.nl
- **Homepage:** https://www.yuki.nl/

## When to use this skill

Activate this skill when the user explicitly wants to work with **Yuki** — for example, "create an invoice in Yuki" or "reconcile payments in Yuki". This skill teaches the agent:

1. Which Apideck unified API covers Yuki (Accounting)
2. The correct `serviceId` to pass on every call (`yuki`)
3. Yuki-specific auth and coverage caveats

For the full method surface (parameters, pagination, filtering), use your language SDK skill:

- [`apideck-node`](../../skills/apideck-node/), [`apideck-python`](../../skills/apideck-python/), [`apideck-dotnet`](../../skills/apideck-dotnet/), [`apideck-java`](../../skills/apideck-java/), [`apideck-go`](../../skills/apideck-go/), [`apideck-php`](../../skills/apideck-php/), or [`apideck-rest`](../../skills/apideck-rest/)

For the raw OpenAPI spec:

- **Accounting:** [https://specs.apideck.com/accounting.yml](https://specs.apideck.com/accounting.yml) · [API Explorer](https://developers.apideck.com/api-explorer?id=accounting)

## Minimal example (TypeScript)

```typescript
import { Apideck } from "@apideck/unify";

const apideck = new Apideck({
  apiKey: process.env.APIDECK_API_KEY,
  appId: process.env.APIDECK_APP_ID,
  consumerId: "your-consumer-id",
});

// List invoices in Yuki
const { data } = await apideck.accounting.invoices.list({
  serviceId: "yuki",
});
```

## Portable across 34 Accounting connectors

The Apideck **Accounting** unified API exposes the same methods for every connector in its catalog. Switching from Yuki to another Accounting connector is a one-string change — no rewrite, no new SDK.

```typescript
// Today — Yuki
await apideck.accounting.invoices.list({ serviceId: "yuki" });

// Tomorrow — same code, different connector
await apideck.accounting.invoices.list({ serviceId: "access-financials" });
await apideck.accounting.invoices.list({ serviceId: "acumatica" });
```

This is the compounding advantage of using Apideck over integrating Yuki directly: code against the unified Accounting API once, gain access to every connector in it. New connectors Apideck adds become available to your app without code changes.

## Yuki via Apideck Accounting

Yuki is a Dutch cloud accounting and bookkeeping platform, strong in automated document processing and NL/BE SMB markets.

### Entity mapping

| Yuki entity | Apideck Accounting resource |
|---|---|
| Sales Invoice | `invoices` |
| Purchase Invoice | `bills` |
| Journal Entry (GB-mutation) | `journal-entries` |
| GL Account | `ledger-accounts` |
| Customer (Debtor) | `customers` |
| Supplier (Creditor) | `suppliers` |
| BTW code | `tax-rates` |
| Cost centre | `tracking-categories` |
| Company (Administration) | `company-info` |
| Attachments | `attachments` |

### Coverage highlights

- ✅ CRUD on invoices, bills, customers, suppliers
- ✅ Journal entries and Dutch BTW handling
- ✅ Tracking categories (cost centres)
- ✅ Document attachments (Yuki's OCR output)
- ❌ Automated document recognition workflow (Yuki's signature feature) — not exposed; use Proxy
- ❌ Bank reconciliation rules — use Proxy

### Auth notes

- **Type:** API key, managed by Apideck Vault
- **Administration-scoped:** Yuki API keys are tied to a single administration (tenant). Multi-admin customers need one connection per admin.
- **Permission scope:** key inherits the generator's role — admin-level access recommended for full coverage.

### Example: list invoices for a specific period

```typescript
const { data } = await apideck.accounting.invoices.list({
  serviceId: "yuki",
  filter: { updated_since: "2026-01-01T00:00:00Z" },
});
```

## Escape hatch: Proxy API

When an endpoint isn't covered by the Accounting unified API, use Apideck's Proxy to call Yuki directly — Apideck injects auth headers and handles token refresh. Set `x-apideck-downstream-url` to the target endpoint on Yuki's own API:

```bash
curl 'https://unify.apideck.com/proxy' \
  -H "Authorization: Bearer ${APIDECK_API_KEY}" \
  -H "x-apideck-app-id: ${APIDECK_APP_ID}" \
  -H "x-apideck-consumer-id: ${CONSUMER_ID}" \
  -H "x-apideck-service-id: yuki" \
  -H "x-apideck-downstream-url: <target endpoint on Yuki>" \
  -H "x-apideck-downstream-method: GET"
```

See [Yuki's API docs](https://api.yukiworks.nl) for available endpoints.

## Sibling connectors

Other **Accounting** connectors that share this unified API surface (same method signatures, just change `serviceId`):

[`access-financials`](../access-financials/) *(beta)*, [`acumatica`](../acumatica/) *(beta)*, [`banqup`](../banqup/) *(beta)*, [`campfire`](../campfire/) *(beta)*, [`clearbooks-uk`](../clearbooks-uk/) *(beta)*, [`digits`](../digits/) *(beta)*, [`dualentry`](../dualentry/), [`exact-online`](../exact-online/), and 25 more.
