+# Exceptions
+Google Places API may throw various exceptions based on the given `$params` or response and is located in the `SKAgarwal\GoogleApi\Exceptions` namespace.
+
+- A `GooglePlacesApiException` is thrown when no `API KEY` is provided or  `$params` is invalid. 
+**Note:** This is the parent class for the preceding exceptions.
+- A `InvalidRequestException` is thrown when the response `status` is `INVALID_REQUEST`
+- A `OverQueryLimitException` is thrown when  the response `status` is `OVER_QUERY_LIMIT`
+- A `RequestDeniedException` is thrown when  the response `status` is `REQUEST_DENIED`
+- A `UnknownErrorException` is thrown when  the response `status` is `UNKNOWN_ERROR`
+- A `NotImplementedException` is thrown when the response cannot be determined.
+
+If any of these exception has been thrown, you can use the `getErrorMessage()` method to get the `error_message` field from the response if any is provided. 
+**Note:** `error_message` field is not guaranteed to be always present, and its content is subject to change.
