 Interaction with the APIs is done via the `Api` singleton. The Api singleton provides access to a configured Ktor client for interaction with the Api. A session token can also be applied:
 
 ```kotlin
-Api.sessionToken = "valid_session_token"
+Api.applySessionToken("valid_session_token")
+```
+
+### Applying Ktor config
+Ktor configuration can be applied using the `Api.withHttpClientConfig` method:
+
+```kotlin
+Api.withHttpClientConfig {
+    install(Logging) {
+        level = LogLevel.ALL

 ### Routers
-Routers are used to encapsulate specific areas of the API. For example, the `VehiclesRouter` takes care of all Vehicle API interactions. Routers are attached to the `Api` object via extension properties.
