How Can I Set Up the Integration of ZEP and Personio?

To start the activation in Personio, follow these steps:

  1. Go to the Marketplace and search for the integration.
  2. Click on the integration to open the drawer with further details.
  3. Select Connect to start the activation process.
  4. Click Generate new API credentials.
  5. Copy the client ID and secret and click Go to website to finish the setup in the partner's service environment.


The interface between ZEP and Personio is configured in ZEP under Administration > Settings > Personio. For the setup, you can choose between two different settings.

Setting 1: Synchronize Employee-IDs by email address

The Personio employee ID must be stored for each ZEP user to ensure that users' time entries are correctly matched during synchronization with Personio. The Personio employee ID can be entered manually in ZEP for each user. To minimize manual entries, the Personio task supports the automatic detection and transfer of Personio employee IDs based on employees' email addresses.

If a user has been created with an identical email address in both ZEP and Personio, the task automatically uses the Personio user's employee ID for the ZEP user. You can enable or disable this automatic transfer. Only time entries of ZEP users with a stored Personio ID are transferred during synchronization. Changes to time entries are not logged in ZEP until the employee-ID of the user has been set in ZEP.

Setting 2: Aggregate Time Postings by Day

If this option is selected, ZEP aggregates the time postings for a day into a single Personio attendance with the correct duration, deducting breaks if applicable. If this option is not selected, all time entries are transferred to Personio per employee and day. In this case, Personio creates a relevant attendance for each ZEP time entry.

Setting Up the Personio Task

The Personio task is scheduled in ZEP under Administration > System > Tasks. Click on the link Create new task and select the task Synchronization of time postings with Personio. Next, you need to specify the time intervals at which the task should be performed. If you have activated the option Synchronize Employee IDs Using Email Address in the settings, you should now start the task manually, just once. This causes the application to detect and assign Personio employee IDs based on email addresses. Any changes in time postings will then be logged for synchronization with Personio.


Which Data Is Transferred?

Time entries recorded in ZEP are regularly transferred to Personio, where they are stored as attendances. Time postings are synchronized via a ZEP scheduler task, which can be scheduled for regular execution. When the task is executed, all time postings that have been newly created, changed or deleted for each user since the last execution are detected and matched with the respective attendances in Personio.


How Much Does It Cost?

ZEP offers the products ZEP Clock and ZEP. ZEP Clock is available from €1 per user per month. The price for ZEP is calculated depending on the range of functions and selected modules.
