 Any exception thrown by the client directly will implement `HelpScout\Api\Exception` and HTTP errors will result in `Http\Client\Exception\RequestException` being thrown.
 
+### Validation
+
+You'll encounter a `ValidationErrorException` if there are any validation errors with the request you submitted to the API.  Here's a quick example on how to use that exception:
+
+```php
+try {
+    // do something
+} catch (\HelpScout\Api\Exception\ValidationErrorException $e) {
+    $error = $e->getError();
+
+    var_dump(
+        // A reference id for that request.  Including this anytime you contact Help Scout support will enable
+        // us to help you much more quickly
+        $error->getLogRef(),
+
+        // Details about the invalid fields in the request
+        $error->getErrors()
+    );
+    exit;
+}
+```
+
+
 ## Pagination
 
 When fetching a collection of entities the client will return an instance of `HelpScout\Api\Entity\Collection`. If the end point supports pagination then it will return an instance of `HelpScout\Api\Entity\PagedCollection`.
