How to Send MemberPress Data to Fortnox

Fortnox is an accounting platform for managing finances. Here is how to pipe MemberPress membership straight into Fortnox using Advanced Form Integration. The setup takes about five minutes and runs entirely on your own server.

The direct approach

AFI delivers membership data straight from WordPress to Fortnox. No third-party cloud, no per-task fees, and every request is logged for troubleshooting.

What you will need

• A WordPress site with MemberPress installed and configured.
• A Fortnox account.
• The Advanced Form Integration plugin (free from WordPress.org).

Connect Fortnox to AFI

Fortnox uses OAuth 2.0 for authentication. In AFI → Settings → Fortnox, click Authorize and grant access. This is a one-time step.

Setting up the integration

1. Create a new integration

Go to AFI → Add New. Name it MemberPress to Fortnox.

2. Pick your trigger

Select MemberPress as the form provider. AFI fires when a member registers or a subscription transaction completes, giving you access to member name, email, membership level, transaction amount, and subscription status.

3. Select Fortnox as the destination

Choose Fortnox from the platform dropdown and pick Add Customer. This creates a customer in Fortnox.

4. Map fields

Match each Fortnox field on the left to the corresponding MemberPress field on the right. Common mappings include member name, email, membership level, transaction amount, and subscription status. You can also use smart tags like {{_submission_date}}.

5. Add conditions if needed

Only want to send certain records? Set up a conditional rule based on any field value.

6. Save and test

Click Save Integration. Trigger a test event in MemberPress. Check Fortnox to confirm the data arrived. If anything looks wrong, open AFI → Log to see the exact request and response.

Free vs Pro

The free version maps name and email to Fortnox with unlimited records. Pro adds custom field mapping. No per-record fees on any plan.

Will adding this slow down my site?
