+
+        Args:
+            distribution (str): Allowed values: `hour`, `day`, `day-hours`, `month` or `year`. Defaults to `day`.
+            timezone (str): IANA Time Zone (e.g. America/Phoenix).
+                            Defaults to the requester's timezone.
+                            When the requester's timezone isn't present, then `filters.from` is parsed to get the timezone.
+            filters (dict): If none provided, your report will span the last seven days.
+            payload (dict): Custom payload to be used as request's data.
+                            It overrides all other parameters provided for the method.
+            headers (dict): Custom headers to be used with session headers.
+                            They will be merged with session-level values that are set,
+                            however, these method-level parameters will not be persisted across requests.
+
+        Returns:
+            httpx.Response: The Response object from `httpx` library,
+                            which contains a server's response to an HTTP request.
