# Attach library documents to a package

> Copies documents from the library into a DRAFT package, with their fields. `roleMap` maps each of the document's library role ids (from `GET /api/v1/library/documents`) to a recipient id on this package; a role left out or mapped to null leaves its fields unassigned. The package keeps its own copy, so later edits never reach the library. Requires canSendPackages.

  description: >-
    Public v1 API for FlowSign. Every endpoint is authenticated with a Bearer
    API key (prefix `fsk_`). Errors use `{ error, details? }`; success responses
    wrap payload data as `{ data }`.


    An organisation is divided into workspaces. A key belongs to the
    organisation and acts in one workspace per request: pass `X-Workspace-Id`
    (see `GET /api/v1/workspaces`) or omit it to act in the default workspace.
    Packages, templates, contacts and members are scoped to the workspace the
    call acts in.
