OCS Share API
=============

The OCS Share API allows you to access the sharing API from outside over
pre-defined OCS calls.

The base URL for all calls to the share API is: *<nextcloud_base_url>/ocs/v2.php/apps/files_sharing/api/v1*

All calls to OCS endpoints require the ``OCS-APIRequest`` header to be set to ``true``.

.. _Share attributes:

Share attributes
~~~~~~~~~~~~~~~~

Share attributes are used for more advanced flags like permissions.

.. code-block:: json

    [
        { "scope": "permissions", "key": "download", "value": false }
    ]

.. warning:: Since Nextcloud 30, the ``enabled`` key have bee renamed to ``value`` and supports more than boolean.
 
Download permission
"""""""""""""""""""

To remove the download permission from a share, use the following serialized string in the "attributes" parameter:

.. code-block:: json

    [
        { "scope": "permissions", "key": "download", "value": false }
    ]


This will prevent users from downloading the files from the share.
For specific file types like office files, it will still be possible to view the files using the appropriate viewer app,
which itself will present the file in a way that downloading will not be allowed.

By default when unset, the "download" attribute will be true and so the download permission will be granted.

File request
""""""""""""

When creating a link or mail share, you can enable the file request feature.
It will ask recipients to enter their name and all uploaded files will be stored in a
separate folder with the provided name.

.. code-block:: json

    [
        { "scope": "fileRequest", "key": "enabled", "value": true }
    ]

When creating the file request, you can also provide an array of emails.
Traditionally, only one is allowed with the `shareWith` parameter,
but you can provide a list of emails via attributes. This only works for MAIL shares.

.. code-block:: json

    [
        { "scope": "fileRequest", "key": "enabled", "value": true },
        { "scope": "shareWith", "key": "emails", "value": ["maria@company.com", "paul@company.com"] }
    ]

.. note:: You will have to provide an empty string as `shareWith` parameter when creating the share.
   Updating or creating the share with those parameters, will NOT send an email to the recipients.
   You will have to use the `send-email` endpoint to send the email.

.. _Send email:

Send email
~~~~~~~~~~

Send an email to the recipients of a share.

* Syntax: /shares/*<share_id>*/send-email
* Method: POST

* Arguments: share_id - (int) share ID
* POST Arguments: password - (string) the share password if enabled.

Statuscodes:

* 200 - successful
* 400 - wrong or no update parameter given
* 403 - no permission to send email on this share
* 404 - couldn't find the share

Federated Cloud Shares
----------------------
