# StartTripCallback

This interface is used with [`startTrip(Map<String, String>, TransportMode, StartTripCallback)`](/sdk/api-reference/android/sentiance.md#starttrip-map-transportmode-starttripcallback).

### StartTripCallback API

#### `onSuccess()`

> ```java
> void onSuccess()
> ```
>
> Called when a trip is successfully started.

#### `onFailure()`

> ```java
> void onFailure(@Nullable SdkStatus sdkStatus)
> ```
>
> Called when a trip start fails. Check the [`SdkStatus`](/sdk/api-reference/android/sdkstatus.md) object to find out why.
