Before you can make payments using the Yoco Web POS integration, you will need to add your devices (card readers) to SalonBridge.
From the SalonBridge console, click on 'My Business->Integrations':
Click on 'View/Edit Devices' on the Yoco Web POS integration to add the device.
The device name can be anything you choose, but should be something descriptive, such as 'Neo Touch Reception' or 'Khumo Print Upstairs', so that when capturing a payment, it is clear which device the payment will be sent to. Once you have given the device a name, click on 'Add Device'.
