# Get build info by process instance

> Retrieve the build associated with a running process instance, including the build settings used to render its UI.

> [!TIP]
>
> Looking for end-to-end guidance on calling FlowX from your own app? See [Consuming FlowX from external apps](https://docs.flowx.ai/6.x/docs/platform-deep-dive/integrations/consuming-flowx-from-external-apps.md).

Returns the build that an already-started process instance is running on, with its associated build settings. Renderers call this when continuing a process across page refreshes; an external app would call it to discover the build version a process started against (for example, before fetching media files, substitution tags, or theme assets keyed by build).

The runtime resolves authorisation by checking that the process instance belongs to a workspace inside your organisation.

## Path parameters

**processInstanceUuid** `string` *required*

The UUID of the process instance.

## Request headers

**Authorization** `string` *required*

Bearer token. Format: `Bearer <token>`.

## Response

Returns a `BuildInfoDTO` with the build identifier, the workspace that owns it, and the build settings (theme, platforms, locale defaults, formatting).

```json theme={"dark"}
{
  "workspaceId": "2ae77b6a-d284-4a0b-ab23-ceaa364c7122",
  "buildId": "7d5560be-3846-49fa-9c17-4059c54c7c5f",

  }
}
```

```bash theme={"dark"}
curl -X GET "{BASE_URL}/api/runtime/process-instance/{processInstanceUuid}/build/info" \
  -H "Authorization: Bearer <token>"
```
