# Fetch an entry version

> Retrieve the GOBL envelope data stored for a specific version of a Silo entry.

Use the `version` value returned in an entry's `version` or `versions` fields to retrieve that exact historical envelope. The response contains only the requested version identifier and its GOBL envelope data; other entry metadata remains available from the standard [fetch entry](/api-ref/silo/entries/fetch-an-entry) endpoint.
