# Install a library persona into the caller's workspace

`POST /v1/library/personas/{persona_id}/install`

## Path parameters

- `persona_id` string, uuid, required

## Request body

- InstallPersonaRequest — POST body for ``/v1/library/personas/{id}/install``. ``name_override`` lets callers pick a non-default name on install, typically when re-installing a template that already has a copy in the target org. When omitted, the service appends ``" (2)"``, ``" (3)"``, etc. to deduplicate against existing org personas.
  - `name_override` string, nullable
