The Vonage Business Cloud Extension API enables you to retrieve information about extensions.
Your application must subscribe to the Provisioning API suite to use this API.
Use this page to mock Extension API in your testing and development.
Run our mock API sample using the open source WireMock library, or in the free edition of WireMock Cloud. You'll have a working API server simulating the behavior of Extension API, which will allow you to keep building and testing even if the actual API you isn't currently available.
