VoxAPI, or Application Programming Interface, is a Web module that enables Voxbone customers to automate the ordering and configuration of phone numbers and channels. It is a SOAP (Simple Object Access Protocol)-based Web service that allows customers to integrate number ordering and configuration functions with any of their front- or back-office applications. Communications between customer applications and Voxbone's API are secured through IP address-based access control, SHA-1 authentication security and SOAP over HTTPS support.

VoxAPI Enabler



Voxbone provides an open-source software development kit (SDK libraries) to help developers integrate VoxAPI. Because these libraries are open-source (LGPL license), Voxbone has made them publicly available to the SourceForge community. A description of all XML requests and responses offered by VoxAPI can be found on http://sourceforge.net/projects/voxbone-client/

The WSDL (Web Service Description Language) file can be found at http://sandbox.voxbone.com/VoxAPI/services/VoxAPI?wsdl

The API Sandbox is an isolated testing environment that allows developers to test their integration with VoxAPI without any risk. Using the sandbox, customers can virtually order numbers, add money to their prepaid accounts and modify number configuration.

The Sandbox is only available for registered users. To register for a free account, please visit http://www.voxbone.com/register.jsf. To log into the sandbox, you can use the same username and password as for accessing our web portal. To get started, you need to specify the IP address you will be accessing the sandbox from on https://www.voxbone.com/members/allowedIPAddress.jsf. Please note that all changes made to your account parameters are replicated to the sandbox once a day at 7 a.m. GMT. In practice this means that you will only be able to access the sandbox the day after you have created your account and specified your IP address.
