   <pre>Writes a single user event from the browser. This uses a GET request to due to browser restriction of POST-ing to a third-party domain. This method is used only by the Discovery Engine API JavaScript pixel and Google Tag Manager. Users should not call this method directly.
 
 Args:
-  parent: string, Required. The parent DataStore resource name, such as `projects/{project}/locations/{location}/collections/{collection}/dataStores/{data_store}`. (required)
+  parent: string, Required. The parent resource name. If the collect user event action is applied in DataStore level, the format is: `projects/{project}/locations/{location}/collections/{collection}/dataStores/{data_store}`. If the collect user event action is applied in Location level, for example, the event with Document across multiple DataStore, the format is: `projects/{project}/locations/{location}`. (required)
   ets: string, The event timestamp in milliseconds. This prevents browser caching of otherwise identical get requests. The name is abbreviated to reduce the payload bytes.
   uri: string, The URL including cgi-parameters but excluding the hash fragment with a length limit of 5,000 characters. This is often more useful than the referer URL, because many browsers only send the domain for third-party requests.
   userEvent: string, Required. URL encoded UserEvent proto with a length limit of 2,000,000 characters.
