+| `create()` | Create a new headline | `meeting_id` (int), `title` (str) | `owner_id` (int, defaults to current user), `notes` (str) |

 !!! note "Filtering"
     Like todos, headlines can be filtered by either `user_id` or `meeting_id`, but not both.
 
+!!! tip "Default Behavior"
+    When calling `list()` without parameters, it returns headlines for the current authenticated user. The `create()` method also defaults `owner_id` to the current user if not specified.
+
 !!! note "Return Values"
     The `update()` and `delete()` methods return `None` instead of boolean values.

+
+!!! info "Async Rate Limiting"
+    The async version of `create_many()` supports a `max_concurrent` parameter (default: 5) to control the maximum number of concurrent requests. This helps prevent rate limiting issues when creating large batches of issues.
+
+    ```python
+    # Process more items concurrently for better performance
+    result = await client.issue.create_many(issues, max_concurrent=10)
+
+    # Process items more slowly to avoid rate limits
+    result = await client.issue.create_many(issues, max_concurrent=2)
+    ```
+
+!!! tip "Bulk Operation Best Practices"
+    - **Best-effort approach**: `create_many()` continues processing even if some issues fail to create
+    - **Check both lists**: Always inspect both `result.successful` and `result.failed` to handle partial failures
+    - **Required fields**: Each issue dict must include `meeting_id` and `title`
+    - **Optional fields**: `user_id` defaults to the authenticated user if not provided
+    - **Error handling**: Failed creations include the original input data and error message for debugging
