If you need to enable auto topups for a customer, you can do this on their radius account.
Go to Radius –> User Accounts –> Edit User –> Data Limits tab
Set “Enable Auto Topups” to “Yes”.
Then choose the auto topup increments you want to top up with each time the
data limit of the account reaches a 100%.
Next, you can set an auto topup limit which is the maximum size of all topups for the month.
A limit of 0 means no maximum limit.
You can also enable notifications to be sent to the customer for each topup.
If a customer needs to enable or update auto topups themselves, they can now do it on their customer portal page.
To access it, log in as a customer, go to the usage screen and then click on “Auto Topup Settings”
