Pennylane (via Apideck)

Access Pennylane 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 Pennylane plumbing.

Beta connector. Pennylane 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.

When to use this skill

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

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

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

• apideck-node, apideck-python, apideck-dotnet, apideck-java, apideck-go, apideck-php, or apideck-rest

For the raw OpenAPI spec:

• Accounting: https://specs.apideck.com/accounting.yml · API Explorer

Minimal example (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 Pennylane
const { data } = await apideck.accounting.invoices.list({
  serviceId: "pennylane",
});

Portable across 34 Accounting connectors

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

// Today — Pennylane
await apideck.accounting.invoices.list({ serviceId: "pennylane" });

// 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 Pennylane 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.

Pennylane via Apideck Accounting

Pennylane is a French/European cloud accounting and finance platform blending bookkeeping with modern UX. Fast-growing in France; expanding across the EU.

Entity mapping

Pennylane entity	Apideck Accounting resource
Customer Invoice	invoices
Supplier Invoice	bills
Journal Entry	journal-entries
Ledger (Compte)	ledger-accounts
Customer	customers
Supplier	suppliers
Product / Service	invoice-items
VAT rate	tax-rates
Purchase Order	purchase-orders
Quote	quotes
Bank Account	bank-accounts
Analytic dimension	tracking-categories
Attachments	attachments
Bank Feed Statements	bank-feed-statements

Coverage highlights

• ✅ CRUD on invoices, bills, customers, suppliers
• ✅ Purchase orders and quotes (France-typical sales workflow)
• ✅ Analytic dimensions (cost centre / project tracking)
• ✅ Bank feed statements for reconciliation
• ✅ Attachments on invoices / bills (Pennylane's document-centric model)
• ⚠️ French-specific VAT declaration (CA3) — not exposed; use Proxy
• ❌ Payroll features — separate Pennylane surface
• ❌ Bill automation rules — use Proxy

Auth notes

• Type: OAuth 2.0, managed by Apideck Vault
• Company binding: one Pennylane company per connection.
• French market focus: defaults to French-specific tax codes and reporting; users outside France may see reduced functionality.

Example: create a purchase order

const { data } = await apideck.accounting.purchaseOrders.create({
  serviceId: "pennylane",
  purchaseOrder: {
    supplier_id: "supplier_abc",
    line_items: [{ description: "Widgets", quantity: 10, unit_price: 25.5 }],
    currency: "EUR",
  },
});

Escape hatch: Proxy API

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

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: pennylane" \
  -H "x-apideck-downstream-url: <target endpoint on Pennylane>" \
  -H "x-apideck-downstream-method: GET"

See Pennylane's API docs for available endpoints.
