# USAGE

```csharp theme={null}
using Vobiz;

var client = new VobizApiClient("YOUR_AUTH_TOKEN", "YOUR_AUTH_ID");
const string authId = "YOUR_AUTH_ID";

All methods are asynchronous and return a `Task`.

## Calls

```csharp theme={null}
await client.Calls.MakeCallAsync(new MakeCallRequest {
    AuthId = authId, From = "14155551234", To = "+919876543210",
    AnswerUrl = "https://example.com/answer", AnswerMethod = "POST",
});

await client.LiveCalls.ListLiveCallsAsync(...);   // in-progress calls
await client.LiveCalls.GetLiveCallAsync(...);      // one live call
await client.LiveCalls.HangupCallAsync(...);       // hang up
```

## In-call actions

```csharp theme={null}
await client.PlayAudio.CallAsync(...);
