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 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 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 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

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 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.
