Mock sample for your project: Voice API

Enables users to manage their Vonage API Account by programmable means. More information is available here:.

The Dispatch API enables the developer to specify a multiple message workflow. A workflow follows a template. The first one we are adding is the failover template. The failover template instructs the Messages API to first send a message to the specified channel. If that message fails immediately or if the condition_status is not reached within the given time period the next message is sent. The developer will also receive status webhooks from the messages resource for each delivery and read event. This API is currently in Beta.

The Subaccounts API enables you to create subaccounts under your primary account. Subaccounts facilitate differential product configuration, reporting, and billing. The Subaccounts API is released initially with restricted availability. You can read more about the API in the Subaccounts documentation.

The Verify API helps you to implement 2FA (two-factor authentication) in your applications. This is useful for:
Protecting against spam, by preventing spammers from creating multiple accounts
Monitoring suspicious activity, by forcing an account user to verify ownership of a number
Ensuring that you can reach your users at any time because you have their correct phone number

Applications V1 is deprecated
This version of the API has been deprecated. Please use version 2 going forwards
A Nexmo application contains the security and configuration information you need to connect to Nexmo endpoints and easily use our products.

The Media API can be used to query, download and delete media items such as audio files for use with other Nexmo APIs.

The Messages API consolidates and normalises exchanges across all messaging channels. It allows you to use a single API to interact with our various channels such as SMS, MMS, WhatsApp, Viber and Facebook Messenger

The External Accounts API is used to manage accounts for Viber Business Messages, Facebook Messenger and Whatsapp for use in the Messages and Dispatch APIs.

With the SMS API you can send SMS from your account and lookup messages both messages that you've sent as well as messages sent to your virtual numbers. Numbers are specified in E.164 format. More SMS API documentation is at

The Conversation API enables you to build conversation features where communication can take place across multiple mediums including IP Messaging, PSTN Voice, SMS and WebRTC Audio and Video. The context of the conversations is maintained though each communication event taking place within a conversation, no matter the medium.

The Conversion API allows you to tell Nexmo about the reliability of your 2FA communications. Sending conversion data back to us means that Nexmo can deliver messages faster and more reliably.
The conversion data you send us is confidential: Nexmo does not share it with third parties.
In order to identify the carriers who provide the best performance, Nexmo continually tests the routes we use to deliver SMS and voice calls. Using Adaptive Routing™, Nexmo actively reroutes messages through different carrier routes and ensures faster and more reliable delivery for your messages. The route choice is made using millions of real-time conversion data points.

The Reports API enables you to request a report of activity for your Vonage account.
Depending on your query pattern, you can choose from one of the two versions of the Reports API: asynchronous and synchronous. The asynchronous version is optimized for infrequent and large data queries (from several records to tens of millions). The synchronous version is optimized for frequent and periodic retrievals of small batches of data records (from one record to tens of thousand per query).
Only synchronous version supports retrival of data records by message/record ID.
Vonage recommends that you limit asynchronous queries to a maximum of 20 million records, by setting the start and end dates accordingly. On average, the asynchronous Reports API takes 5 - 10 minutes to generate 1 million records.
