Acumatica (via Apideck)

Access Acumatica 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, banqUP, Campfire 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 Acumatica plumbing.

Beta connector. Acumatica 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 Acumatica — for example, "create an invoice in Acumatica" or "reconcile payments in Acumatica". This skill teaches the agent:

1. Which Apideck unified API covers Acumatica (Accounting)
2. The correct serviceId to pass on every call (acumatica)
3. Acumatica-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 Acumatica
const { data } = await apideck.accounting.invoices.list({
  serviceId: "acumatica",
});

Portable across 34 Accounting connectors

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

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

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

This is the compounding advantage of using Apideck over integrating Acumatica 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.

Acumatica via Apideck Accounting

Acumatica is a cloud ERP platform for mid-market businesses, with strong distribution, manufacturing, and services verticals. Apideck coverage targets the core financial management surface.

Entity mapping

Acumatica entity	Apideck Accounting resource
AR Invoice	invoices
AP Bill	bills
Payment	payments
Credit Memo	credit-notes
GL Transaction	journal-entries
Account	ledger-accounts
Customer	customers
Vendor	suppliers
Inventory Item	invoice-items
Tax	tax-rates
Purchase Order	purchase-orders

Coverage highlights

• ✅ Full CRUD on invoices, bills, payments, customers, suppliers
• ✅ Journal entries
• ✅ Purchase orders
• ✅ Credit notes
• ⚠️ Acumatica Generic Inquiries — powerful custom reports; not exposed, use Proxy
• ❌ Manufacturing and distribution modules — use Proxy for BOM, work orders, shipments
• ❌ Payroll

Auth notes

• Type: OAuth 2.0, managed by Apideck Vault
• Tenant + branch binding: Acumatica supports multi-tenant + multi-branch. The connection is bound to one tenant; branch selection is typically passed per call.
• Screen-based APIs: Acumatica has both OData-style REST and "Screen-Based" Contract API. Apideck abstracts this; Proxy calls can hit either.

Example: create an AR invoice

const { data } = await apideck.accounting.invoices.create({
  serviceId: "acumatica",
  invoice: {
    customer_id: "cust_abc",
    invoice_date: "2026-04-18",
    line_items: [
      { description: "Consulting", quantity: 10, unit_price: 150 },
    ],
    currency: "USD",
  },
});

Escape hatch: Proxy API

When an endpoint isn't covered by the Accounting unified API, use Apideck's Proxy to call Acumatica directly — Apideck injects auth headers and handles token refresh. Set x-apideck-downstream-url to the target endpoint on Acumatica'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: acumatica" \
  -H "x-apideck-downstream-url: <target endpoint on Acumatica>" \
  -H "x-apideck-downstream-method: GET"

See Acumatica's API docs for available endpoints.
