To use the Loket integration, your company needs a legal entity based in the Netherlands. 🇳🇱
This article gives an overview of the employee attributes supported by the Loket integration.
Review supported attributes
During the integration setup, our support team configures your Personio account with all the necessary attributes.
The integration doesn't support custom attributes you create yourself, and you need to handle these manually. You can spot custom attributes in Personio by navigating to Settings > Organisation > Personal information. Custom attributes have the prefix “dynamic”.
The following table outlines all attributes supported by the employee data sync.

Notes:
IBAN: Loket can have different IBANs for different payroll components. The integration only syncs the IBAN to the Loket component "NETTOLOON (260)" (Payroll Bank payment Sepa Bank payment IBAN).
Income number: Loket recommends not entering 0 as the income relationship number. If you enter 0, the sync completes, but Loket includes the following message in the sync results: "NB: Income relationship number is filled with the value 0." You don't need to take any action, as this is a notification from Loket, not an error.
