Fortnox connects to Control through OAuth. The person authorizing the connection must be able to select the intended Fortnox company and approve the requested accounting permissions.

​
Connect in Control

  1. Open .
  2. Open the intended entity, choose Add data source, and select Fortnox.
  3. Give the data source a recognizable name.
  4. Choose Connect Fortnox.
  5. Sign in to Fortnox, select the intended company, and approve Control’s access.
  6. Return to Control and confirm that the data source shows as connected.
Access and refresh tokens are stored securely and refreshed automatically.

​
Permissions requested

Control requests these Fortnox OAuth scopes because the connector reads the corresponding resources:
Fortnox scopes cannot be limited to read-only access: each granted scope technically permits both reading and writing. Control only sends read requests to these resources. Do not grant any additional scopes.
The Fortnox company must have the relevant product licenses. Adding scopes later requires reconnecting the data source so Fortnox can issue a new authorization.

​
Data imported

  • Financial years and chart of accounts
  • General-ledger vouchers
  • Cost centers and projects
  • Sales invoices and customer invoice payments
  • Supplier invoices and supplier invoice payments

​
Common problems

  • The wrong company was connected: reconnect the data source and select the company that belongs to the Control entity.
  • Authorization is denied: ask a Fortnox administrator to confirm that your user can approve integrations and the requested scopes.
  • The connection stopped working: the authorization may have been revoked in Fortnox. Reconnect the data source in Control.
