• This document is applicable to the Git version of RADIUSdesk (2021Version)
• We will explain the same API used by a login page that has User Registration enabled.
• To enable user registration on a login page, go to the Dynamic Login Pages applet.
• Select a login page and click Edit
• At the bottom of the Settings sub-tab is a Registration tab.
• There you can enable and fine tune it for the specified login page.

• We assume the FQDN of the RADIUSdesk server is hotspot.radiusdesk.com. Please adapt accordingly.
• http://hotspot.radiusdesk.com/cake3/rd_cake/register-users/new-permanent-user.json

• Let us take a look at the items submitted to the back-end when a user registers and then discuss important items in that list.

{
	"mac": "28-D2-44-20-AA-00",
	"login_page": "demo1",
	"login_page_id": "1",
	"name": "Dirk",
	"surname": "van der Walt",
	"username": "dirkvanderwalt@radiusdesk.com",
	"password": "very$ecu3",
	"phone": "0721235555"
}

• See the following screenshot to get to the login_page_id

• The first hidden column contains the value of login_page_id.

• The MAC Address is the MAC address from the WiFi interface of the device that the user will connect with to the Captive Portal.
• When we use the login page to do the user registration we can extract it from the detail provided to us by CoovaChilli typically.
• When we create something like a mobile app and want to allow someone to register without being connected to the Captive Portal, we can still supply the MAC address of the device using the app.
• Here is some info on how to get it programmatically: https://stackoverflow.com/questions/10831578/how-to-find-mac-address-of-an-android-device-programmatically/13007454

• This is typically what a successful reply will look like

{
    "success": true,
    "data": {
        "active": "active",
        "cap_data": "hard",
        "language": "4_4",
        "user_id": 0,
        "profile_id": 3,
        "realm_id": 1,
        "token": "85eeb70f-2af0-4d45-9fde-1b9a787048ca",
        "username": "dirkvanderwalt@radiusdesk.com",
        "password": "very$ecur3",
        "email": "dirkvanderwalt@radiusdesk.com",
        "extra_name": "mac",
        "extra_value": "28-D2-44-20-04-8D",
        "auto_add": 1,
        "name": "Dirk",
        "surname": "van der Walt",
        "phone": "0721235555"
    }
}

• This is a typical message if someone tries to register twice from the same device

{
    "success": false,
    "errors": {
        "username": "MAC Address 28-D2-44-20-04-8D in use by dirkvanderwalt@gmail.com@demo1"
    }
}
