Fortnox error: 2000107

Description

The error occurs when the Integration Platform tries to export an invoice to Fortnox.
The log says:
Invoice Some(#7465): Trying to find customer for billing email=EmailAddress(.....) Invoice Some(#7465): No customer found so will create one. GenericError(20007005, RemoteSystemError): Fortnox error: 2000107 - Värdet är för långt (33000GNOSJÖ) 

This means that the Integration Platform is trying to create a new customer in Fortnox because the customer was not found, but one of the field values being sent exceeds the maximum length allowed by Fortnox. In this case, it appears to be the postal code + city that is too long.

Cause

• Incorrectly combined address field: Postal code and city are written together without a space.

• Field value exceeds max length: Fortnox has strict limitations on the length of fields such as postal code, city, and address.

• Data error in the source system: The information is incorrectly entered or mapped in the source system and is then passed to Fortnox.

Action

• Check the customer’s address data in the source system

  • Verify the fields for Postal code and City.

  • Ensure that they are separate fields with the correct format.

• Correct the address on the order/invoice in the Integration Platform

  • Make sure the postal code is sent in the correct field and that the city is sent separately.

  • Re-run the export after correcting the customer data.

• Correct data in Fortnox (if the customer was already partially created)

  • Log in to Fortnox and check if the customer has been created with incorrect fields.

  • Manually correct the data and synchronize again.

Summary

The error occurs because the postal code and city are incorrectly combined into one field that is too long. The solution is to separate postal code and city in the source system, check the field mapping in the Integration Platform, and ensure that the data format complies with Fortnox’s field length restrictions.
