# CreateSubscriptionMediaContainer `MediaContainer` is the root element of most Plex API responses. It serves as a generic container for various types of content (Metadata, Hubs, Directories, etc.) and includes pagination information (offset, size, totalSize) when applicable. Common attributes: - identifier: Unique identifier for this container - size: Number of items in this response page - totalSize: Total number of items available (for pagination) - offset: Starting index of this page (for pagination) The container often "hoists" common attributes from its children. For example, if all tracks in a container share the same album title, the `parentTitle` attribute may appear on the MediaContainer rather than being repeated on each track. ## Fields | Field | Type | Required | Description | | ---------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------- | | `Identifier` | *string* | :heavy_minus_sign: | N/A | | `Offset` | *long* | :heavy_minus_sign: | The offset of where this container page starts among the total objects available.
