# Share Endpoints

Share endpoints allow sharing files with other users.

## POST `/share` (auth required)

### Description

The `/share` endpoint shares 1 or more filesystem items
with one or more recipients. The recipients will receive
some notification about the shared item, making this
different from calling `/grant-user-user` with a permission.

    - **path:** _alias for uid_
    - **name:** name of app
    - **access:**
      - `"read"` or `"write"` for files (default: `"read"`)
      - unspecified for apps
  - **notes:**
