The Ordering module contains 10 methods that allow purchasing Voxbone services.
AccountBalance API: This method is used to retrieve information about your account balance. You may need to check your account balance before checking out your carts. This is not mandatory, but checking out a cart with an empty balance will return an error. Note that you can set up a threshold for automatic refills of your business account. This threshold is configurable both on the web portal and the API. We recommend that this automatic refill parameter is set to true, especially when using the API for ordering.
