Mock sample for your project: Conversation API

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

The API to retrieve pricing information.
Please note the Pricing API is rate limited to one request per second.

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 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 Numbers API enables you to manage your existing numbers and buy new virtual numbers for use with the Vonage APIs. Further information is here:

Vonage provides an Application API to allow management of your Vonage Applications.
This API is backwards compatible with version 1. Applications created using version 1 of the API can also be managed using version 2 (this version) of the API.

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.

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 Voice API lets you create outbound calls, control in-progress calls and get information about historical calls. More information about the Voice API can be found 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 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.

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.
