## Phrase Content Groups API Reference 1.0.16

Content Groups are organization-scoped named containers that connect platform objects across the Phrase product suite. They act as the single matching principle for the translation and quality workflow: a TMS project, its Style Guides, Style Rules, and AI quality checks all resolve through a shared Content Group.

### Key Features

* **Full group management** — create, retrieve, update, and delete Content Groups for your organization
* **Reference listing** — retrieve the platform objects linked to a group, with optional filtering by `objectType`
* **Typed object references** — supported types are `TMS_PROJECT`, `PLATFORM_STYLE_GUIDE`, `PLATFORM_STYLE_RULE`, and `PLATFORM_QA_CHECK`

### How Content Groups fit into the platform

Content Groups are the coordination layer across Phrase products. Once a TMS project is linked to a Content Group:

* The project's Style Guide and Style Rules are resolved from the group
* Quality Evaluation draws its checks from the `(Content Group, locale)` pair
* AI capabilities receive a Content Profile derived from the group's rules
