Conversation

A conversation is a shared core component that Nexmo APIs rely on. Conversations happen over multiple mediums and and can have associated Users through Memberships.

User

The concept of a user exists in Nexmo APIs, you can associate one with a user in your own application if you choose. A user can have multiple memberships to conversations and can communicate with other users through various different mediums.

Member

Memberships connect users with conversations. Each membership has one conversation and one user however a user can have many memberships to conversations just as conversations can have many members.

Audio

Audio streams can be enabled and disabled in a Conversation so that Members can communicate with voice.

Media Events

Media events will fire in a Conversation when media state changes for a member. This can be when an Audio stream is started or ended.
