Configure product marking codes and check the sale authorization mode.
Who this guide is for: owners and managers. Before making changes, make sure the correct establishment is selected.
Before you begin
- Sign in to the appropriate workspace and check the establishment name at the top of the page.
- Prepare the information you will enter. Payment and integration settings also require the provider's connection details.
- If an option is missing, check your plan and your role's permissions.
Setup steps
- Prepare the certificate and token. Follow the requirements in your Chestny Znak account.
- Select product groups. Enable only the groups used by the establishment.
- Configure scanning. The complete code must be added to the order without manual shortening.
- Run a test. Test a valid code, an already used code and a prohibited code.

Check the result
A prohibited code is blocked from sale with a clear reason; successful withdrawal from circulation retains the service's original response.
Troubleshooting
- Refresh the page and select the establishment again. Some data is only shown for the selected establishment.
- Check required fields, phone number format, dates and numeric values. Save errors appear on the right below the header.
- Do not create a duplicate just because a response is slow. Open the list first and check whether the record has already been created.
