Exact Online UK (via Apideck)

Access Exact Online UK 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 Exact Online UK plumbing.

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

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

Portable across 34 Accounting connectors

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

// Today — Exact Online UK
await apideck.accounting.invoices.list({ serviceId: "exact-online-uk" });

// 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 Exact Online UK 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.

Exact Online UK via Apideck Accounting

UK-specific variant of Exact Online. Use this connector when the user's Exact instance is on the UK data center. Coverage mirrors exact-online.

When to use this vs exact-online

User scenario	Use
User's division is in the UK	exact-online-uk
User's division is in the Netherlands	exact-online-nl
User's division is in Belgium or other EU	exact-online

Entity mapping + coverage

Identical to exact-online. See that skill for the full mapping table and coverage highlights.

Key UK-specific behaviors:

• VAT handling: UK 20% / 5% / 0% rates; Brexit-era rules (reverse charge on EU imports) handled through tax-rates.
• Making Tax Digital (MTD) compliance: UK divisions may have MTD-specific fields on invoices (HMRC submission). Use Proxy for MTD submission endpoints not covered by the unified model.
• Currency: typically GBP-denominated; multi-currency supported for international customers.

Auth notes

• Type: OAuth 2.0, managed by Apideck Vault
• Data center: start.exactonline.co.uk. Wrong-DC errors = wrong connector variant.

Example: list customers with invoices due in 30 days

const { data: invoices } = await apideck.accounting.invoices.list({
  serviceId: "exact-online-uk",
  filter: { status: "open" },
});

Verifying coverage

Not every Accounting operation is supported by every connector. Always verify before assuming a method works:

curl 'https://unify.apideck.com/connector/connectors/exact-online-uk' \
  -H "Authorization: Bearer ${APIDECK_API_KEY}" \
  -H "x-apideck-app-id: ${APIDECK_APP_ID}"

See apideck-connector-coverage for patterns around UnsupportedOperationError and connector-specific fallbacks.

Escape hatch: Proxy API

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

See Exact Online UK's API docs for available endpoints.
