This API is provided for developers who want to integrate with or build on top of our voice platform.

Our APIs provide access to resources (data entities) via URI paths. To use a REST API, your application will make an HTTP request and parse the response. By default, the response format is JSON.To use the SOAP API, your application will make a XML/HTTP request and parse the response.

Your methods will be the standard HTTP methods GET and POST.  Because the API is based on open standards, you can use any web development language to access the API.
