3. After the installation, a Self Hosted Http service will be configured on following address bindings to be integrated with POS:
   • http://localhost:8524/api/IMSFiscal/get
   • It will show “Service is responding”
   • Note: To verify the successful installation of fiscal service. Please confirm fiscalization service is up and running in the system services list (service.msc) as shown in Figure -7.
4. Consume the local fiscal service (http://localhost:8524/api/IMSFiscal/get) in the POS according to given instruction in Section Steps of Integration for Http Service Consumption.
5. FBR service will return the invoice number against each record.
