External Services

This plugin connects to external services to function:

  • Peki export service (peki.no) – Processes and forwards order data to Fiken API
  • Fiken API (fiken.no) – Creates accounting vouchers from order data

By using this plugin, you agree to data processing on these external servers. Review their respective privacy policies for details.

Do I need a Fiken account?

Yes, an active Fiken account with API access is required (NOK 99/month add-on).

Can I connect multiple stores?

Yes, unlimited WordPress sites can connect to the same Fiken company and share the monthly transfer quota.

Is the plugin compatible with HPOS?

Yes, the plugin is fully compatible with WooCommerce High-Performance Order Storage.

Is the plugin compatible with WordPress 7?

Yes. The plugin declares compatibility via “Tested up to” and is exercised on WordPress 7.0 with current WooCommerce releases. WordPress 7 raises the project minimum to PHP 7.4 (PHP 8.2+ recommended); keep hosting and WooCommerce updated.

What data is sent to external services?

The plugin sends order data to peki.no (export service) and fiken.no (accounting platform) to create vouchers. Only necessary order and customer information is transmitted. See Terms and Privacy policies on peki.no and fiken.no.

Is my data secure?

Yes, all data is transmitted over secure HTTPS connections.

Update failed with “Could not create folder” on Windows (IIS)?

This is usually either (1) the web server account cannot write to wp-content/upgrade and wp-content/plugins, or (2) the update package was built with the wrong folder layout (there must be exactly one top-level folder named peki-fiken-integration-for-woocommerce). Grant the IIS application pool identity Modify on wp-content (or at least wp-content/upgrade and wp-content/plugins). If the problem persists, install manually: unzip the release so you get wp-content/plugins/peki-fiken-integration-for-woocommerce/fiken.php, or upload via FTP/SFTP.
