There are two ways to obtain the valid BSI certificate number of a TSS:

• Navigate to: Germany > SIGN DE V2 > Technical Security System.

• In the table overview, you will see the BSI certificate number for each TSS.

• On the detail page of the particular TSS, the certificate number is also displayed.  

 

**2. Via fiskaly SIGN DE (ListTss or RetrieveTss endpoint)  **

• Call the listTss endpoint / retrieveTss endpoint.

• The BSI certificate number can be found in the response field data[].bsi_certification_id.
