Step 3: Sync users to activate the integration

  2. Matching users are employees with the same email in both systems.
    • Review which fields have different or missing values.
    • For each case, choose to update Huma with the value from Crona Lön, update Crona Lön with the value from Huma, or leave it as it is.
    • Click "Next".

The status changes to "Connected and active". You get an email with the result.

 

💡 Note

Before you sync, decide which system has the most up-to-date information. The choices you make here overwrite data.
