# Deprecated: filter categories

> available_selection_categories: deprecated; use list_filters instead.

> **Deprecated.** `available_selection_categories` stays available for 12 months from the v2 launch, with 3 emailed notices, then it stops working. Use [`list_filters`](https://emailmovers.com/mydatahub/docs/reference/mcp/list_filters.md) instead.

Deprecated: lists the filter categories. Use list_filters instead. It returns every field by name, such as company.employee_band, with its type, operators and value count. It stops working 12 months after the new tools launch, after three emailed notices; https://emailmovers.com/mydatahub/docs/migrate maps every call. Lawful basis is UK GDPR Article 6(1)(f) legitimate interests; email audiences include corporate subscribers only by default (PECR), so sole traders and ordinary partnerships are left out unless the toggle is changed.
