# Exact Online NL — Accounting API: overview > Canonical URL: https://developers.apideck.com/apis/accounting/exact-online-nl/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 on the Dutch instance - **apideck credentials available:** true - **apideck credentials note:** For testing: OAuth shows Apideck; production requires your own app. The only Exact Online connector with Apideck credentials. - **authentication note:** Authorization Code flow. - **consumer access level:** Any user who can authorise third-party app connections. - **costs:** Developer subscription approx. €15/month per country (excl. VAT); no per-call 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. Test with your Dutch developer subscription, a free 30-day trial on the Dutch production instance, or Apideck's temporary shared test credentials (request access through Apideck Support) — 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. For regions beyond this instance, use exact-online (per-connection region) or exact-online-uk. 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. 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. 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. - **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. - **responsibility matrix:** - **area:** Sign Up for Developer's Subscription - **customer:** ✓ - **apideck:** Docs provided - **area:** Register & Configure App - **customer:** ✓ - **area:** Submit App for Exact Review - **customer:** ✓ - **area:** Add Credentials to Apideck - **customer:** ✓ - **apideck:** Handles OAuth flow - **area:** Authorize Connection (OAuth) - **consumer:** ✓ - **area:** Grant Division Access - **consumer:** ✓ - **apideck:** Maintains connector - **area:** Build via Unified API - **customer:** ✓ - **apideck:** ✓ Automatic - **area:** Token Refresh - **apideck:** Logs & alerts - **area:** Monitor Connections - **consumer:** ✓ Can revoke anytime - **customer:** ✓ Via Apideck Dashboard - **sandbox available:** true - **sandbox note:** Test with your Dutch developer subscription, a free 30-day trial on the production instance, or Apideck's temporary shared test credentials;
