Access Financials (via Apideck)

Access Access Financials through Apideck's Accounting unified API — one of 34 Accounting connectors that share the same method surface. Code you write here ports to Acumatica, 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 Access Financials plumbing.

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

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

Portable across 34 Accounting connectors

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

// Today — Access Financials
await apideck.accounting.invoices.list({ serviceId: "access-financials" });

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

This is the compounding advantage of using Apideck over integrating Access Financials 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.

Access Financials via Apideck Accounting

Access Financials (part of The Access Group) is a UK mid-market accounting platform aimed at enterprise finance teams. Apideck coverage targets the core AR/AP surface.

Entity mapping

Access entity	Apideck Accounting resource
Sales Invoice	invoices
Credit Note	credit-notes
Customer	customers
Supplier	suppliers
Payment	payments
Nominal Account	ledger-accounts
Tax	tax-rates
Tracking / Analysis Code	tracking-categories

Coverage highlights

• ✅ Sales invoices
• ✅ Credit notes
• ✅ Customers, suppliers, payments
• ✅ Chart of accounts
• ✅ Tax rates (UK VAT)
• ✅ Tracking categories
• ⚠️ Purchase invoices — may be partial; verify with connector API
• ❌ UK MTD submissions — use Proxy
• ❌ Payroll — Access offers payroll via a separate product line

Auth notes

• Type: API key, managed by Apideck Vault
• Client binding: one Access Financials client per connection.
• Enterprise-typical onboarding: integration may require coordination with the customer's Access admin team.

Example: list recent customers

const { data } = await apideck.accounting.customers.list({
  serviceId: "access-financials",
  filter: { updated_since: "2026-03-01T00:00:00Z" },
});

Escape hatch: Proxy API

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

See Access Financials's API docs for available endpoints.
