# DELETE /gammas/{gammaId}

Delete a Gamma document. Gamma archives it automatically first if needed, then marks it for deletion.

## Delete a Gamma

> Deletes a Gamma document. Requires workspace admin role on the workspace the API key belongs to. The Gamma is auto-archived first if not already archived, so a single call handles the full archive-then-delete transition. The Gamma becomes immediately inaccessible and is removed from all workspace views. After deletion, the Gamma is no longer addressable via the API; subsequent requests for the same ID return the same response as for a non-existent Gamma.

{% hint style="warning" %}
Deletion requires a workspace admin role on the API key's workspace. A successful response returns `status: deleted`. The Gamma becomes immediately inaccessible and is no longer addressable via the API.
