# Exact Online — Accounting API: overview

> Canonical URL: https://developers.apideck.com/apis/accounting/exact-online/overview

Exact Cloud business software offers accounting and industry software in the cloud for SME's on desktop, laptop, tablet and mobile apps.
- Status: live
- Authentication: oauth2

- **account type required:** Active Exact Online subscription in any supported country edition (NL, BE, DE, ES, UK, US)
- **apideck credentials available:** false
- **authentication note:** Authorization Code flow.
- **consumer access level:** Any user who can authorise third-party app connections; at consent time the app must be granted access to each division (administration) it needs to access.
- **costs:** Developer subscription approx. €15/month per country (excl. VAT); no per-call API charges.
- **difficulty:** moderate
- **difficulty reason:** Paid Developer Subscription + App Review Required for External Consumers
- **environment notes:**   - **description:** Testing and production share the same app credentials, and every environment holds live data — treat anything you write during testing as production data.
  - **environment:** Single environment
- **important to know:** Exact Online runs separate country instances — an app registered in one country cannot serve consumers in another. Select and save the connection's region **before** authorizing; it defaults to the Dutch domain, so non-NL consumers fail otherwise.
Your app must pass Exact's review before consumers outside your own Exact instance can connect — until it does, only your own subscription can be linked, which blocks pilot consumers.
Write-back is limited to transactions (invoices, bills, invoice items, payments, bill payments, bill credit notes, journal entries); master data — customers, suppliers, ledger accounts, tax rates and credit notes — is read-only, so consumers maintain it in Exact Online.
Refresh tokens are single-use and expire after 30 days of inactivity, but Apideck renews them before then, so a dormant connection does not lapse. Re-authorising is needed if access is revoked or a renewal fails.
Exact requires sequential API calls — parallel or multi-threaded requests are explicitly disallowed, so a high-volume sync must be serialised rather than fanned out.
- **partnership note:** Registering your app requires a paid Exact Online developer subscription (per country); App Store listing is optional.
- **partnership required:** true
- **partnership url:** https://www.exact.com/nl/app-store/developer
- **rate limits:** 60 requests/minute and 5,000 requests/day per app per division; Exact Online Premium raises the daily cap to 30,000.
