= Managing Resources

Resource servers can manage their resources remotely using a UMA-compliant endpoint.

[source,subs="attributes+"]
----
http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set
----

This endpoint provides operations outlined as follows (entire path omitted for clarity):

* Create resource set description: POST /resource_set
* Read resource set description: GET /resource_set/{_id}
* Update resource set description: PUT /resource_set/{_id}
* Delete resource set description: DELETE /resource_set/{_id}
* List resource set descriptions: GET /resource_set

For more information about the contract for each of these operations, see https://docs.kantarainitiative.org/uma/wg/oauth-uma-federated-authz-2.0-09.html#reg-api[UMA Resource Registration API].

== Creating a Resource

To create a resource you must send an HTTP POST request as follows:

[source,bash,subs="attributes+"]
----
curl -v -X POST \
  http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set \
  -H 'Authorization: Bearer '$pat \
  -H 'Content-Type: application/json' \
  -d '{
     "name":"Tweedl Social Service",
     "type":"http://www.example.com/rsrcs/socialstream/140-compatible",
     "icon_uri":"http://www.example.com/icons/sharesocial.png",
     "resource_scopes":[
         "read-public",
         "post-updates",
         "read-private",
         "http://www.example.com/scopes/all"
      ]
  }'
----

By default, the owner of a resource is the resource server. If you want to define a different owner, such as an
specific user, you can send a request as follows:

[source,bash,subs="attributes+"]
----
curl -v -X POST \
  http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set \
  -H 'Authorization: Bearer '$pat \
  -H 'Content-Type: application/json' \
  -d '{
     "name":"Alice Resource",
     "owner": "alice"
  }'
----

Where the property `owner` can be set with the username or the identifier of the user.

== Creating User-Managed Resources

By default, resources created via Protection API can not be managed by resource owners through the <<_service_authorization_my_resources, User Account Service>>.

To create resources and allow resource owners to manage these resources, you must set `ownerManagedAccess` property as follows:

[source,bash,subs="attributes+"]
----
curl -v -X POST \
  http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set \
  -H 'Authorization: Bearer '$pat \
  -H 'Content-Type: application/json' \
  -d '{
     "name":"Alice Resource",
     "owner": "alice",
     "ownerManagedAccess": true
  }'
----

== Updating Resources

To update an existing resource, send an HTTP PUT request as follows:

[source,bash,subs="attributes+"]
----
curl -v -X PUT \
  http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set/{resource_id} \
  -H 'Authorization: Bearer '$pat \
  -H 'Content-Type: application/json' \
  -d '{
     "_id": "Alice Resource",
     "name":"Alice Resource",
     "resource_scopes": [
        "read"
     ]
  }'
----

== Deleting Resources

To delete an existing resource, send an HTTP DELETE request as follows:

[source,bash,subs="attributes+"]
----
curl -v -X DELETE \
  http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set/{resource_id} \
  -H 'Authorization: Bearer '$pat
----

== Querying Resources

To query the resources by `id`, send an HTTP GET request as follows:

[source,bash,subs="attributes+"]
----
http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set/{resource_id}
----

To query resources given a `name`, send an HTTP GET request as follows:

[source,bash,subs="attributes+"]
----
http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set?name=Alice Resource
----

By default, the `name` filter will match any resource with the given pattern. To restrict the query to only return resources with an exact match, use:

[source,bash,subs="attributes+"]
----
http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set?name=Alice Resource&exactName=true
----

To query resources given an `uri`, send an HTTP GET request as follows:

[source,bash,subs="attributes+"]
----
http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set?uri=/api/alice
----

To query resources given an `owner`, send an HTTP GET request as follows:

[source,bash,subs="attributes+"]
----
http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set?owner=alice
----

To query resources given an `type`, send an HTTP GET request as follows:

[source,bash,subs="attributes+"]
----
http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set?type=albums
----

To query resources given an `scope`, send an HTTP GET request as follows:

[source,bash,subs="attributes+"]
----
http://${host}:${port}{kc_realms_path}/${realm_name}/authz/protection/resource_set?scope=read
----

When querying the server for permissions use parameters `first` and `max` results to limit the result.
