SignES Setup
The SignES Setup page in LS Central allows you to configure your Fiskaly SIGN ES connection. From this page, you can manage API credentials and test the integration to ensure secure communication between LS Central and the Fiskaly cloud. You can also navigate to Signer Management and Client Management from the page actions.
- Click the
icon, enter SignES Setup, and select the relevant link. - The Base Url field is automatically populated for existing customers.
- Turn on the Enabled toggle to activate Fiskaly SIGN ES.
- Fill in the API Key and API Secret in their respective fields.
- You can test the connection by choosing the Test Connection action.

Test Connection action
The Test Connection action is available from two places, and both invocations perform the same Fiskaly authentication round-trip:
- SignES Setup page - validates the global Base Url, API Key, and API Secret configured on this page.
- Store Card, Fiskaly FastTab - validates the same Base Url together with the store-level Fiskaly API Key and API Secret. Use this entry point before turning a specific store live for fiscalization. See Fiskaly Credentials.
The test does not verify the existence of signers, clients, or taxpayer agreement - those are separate steps. It only confirms that LS Central can authenticate against the Fiskaly API.
Tip: On the Store Card, the Enabled toggle automatically runs Test Connection on validate. If you turn Enabled on without first running the test, you get the same error path.
