This can be done by going to either Global Settings or System Settings depending on how you manage your payments. Use Global settings if you would like to connect one GoCardless account for all your branches/settings. Use System settings if you would like to connect separate GoCardless accounts to individual branches/settings.
Click on the Connect GoCardless button.
Enter your GoCardless credentials or create a new account.
The system will take you back to eyMan and show the success message if the account is connected correctly.
