# Overview

> Section hub for reading and managing tag groups through Fini's public API.

Tag groups are the top-level classification buckets behind [Configuration → Tags](/en/configuration/tags). Every tag belongs to exactly one group. Use these public routes to read both Fini-shipped default groups and workspace-owned custom groups, or to create and manage custom groups from your backend.

<Info>
  The API field `prompt` is the wire-format name for the dashboard's **AI Instructions** field.
</Info>

<Note>
  Read routes return both workspace-owned custom groups and Fini-shipped default groups. In the response, custom groups have a workspace `companyId`, while default groups return `companyId: null`. Mandatory groups, such as Conversation Status, return `mandatory: true`.
