# Provider options
Options related to providers (web and mobile apps, divided into Android, Huawei, and iOS). **Shared options** are applied to all push notifications unless overridden by more specific ones (e.g., web-specific).
The available options include:
* **Priority (push priority):**\
A parameter defining the priority of the push notification. Higher priority ensures faster delivery of the message but may increase battery usage on the user’s device.
* **Topic (push topic):**\
A parameter used for grouping notifications. By assigning a notification to a specific topic, notifications within the same topic will overwrite each other. This ensures the user receives all notifications but only the most recent one is displayed.
* **iOS Subtitle:**\
A parameter available exclusively for iOS, allowing you to add a subtitle to the notification. It is displayed below the main title of the notification and enables the delivery of an additional, concise message that complements the main content.
**Use case:** You are reporting a match score via push notifications. You can overwrite the previous push with the latest score, ensuring that, for example, users who didn’t read earlier messages will only receive the most recent one.
