In plain words
What is it for?
Use it to read, create, update, or reconcile accounting records in the UK version of Exact Online. It is in beta, so coverage may be incomplete.
Why use it?
It avoids building and maintaining a separate Exact Online integration, including authentication, pagination, rate limits, and retries. The connector requires an Exact Online developer subscription and app review for external users.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

exact-online-uk scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 15d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

Quick facts

At a glance

  • Implementation difficulty: moderate — Developer Subscription + App Review Required for External Consumers
  • Vendor partnership required: yes (developer portal) — A UK developer subscription lets you register an app that connects other companies' administrations. UK App Store listing ended 2 Sept 2026.
  • Apideck-managed credentials: not available — Apideck test credentials exist only for the exact-online-nl variant.
  • Account type required: Active Exact Online subscription on the UK instance
  • Consumer access level: Any user who can authorise third-party app connections.
  • Sandbox: available — Test with your UK developer subscription or a free 30-day trial on the UK production instance (no credit card); every environment holds live data.
  • Costs: The UK developer subscription is free; no per-call charges.
  • Rate limits: 60 requests/minute and 5,000 requests/day per app per division; Exact Online Premium raises the daily cap to 30,000.
  • Authentication: Authorization Code flow.
  • Webhooks: No webhooks — Exact Online has native webhooks, but Apideck does not surface them for this connector; sync by polling.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
