====== Systems - Simple: rest api connector ======

===== Basic configuration =====

In this tutorial I will show you how to connect to Dscs rest api. REST api is created by this tutorial: [[https://wiki.czechidm.com/tutorial/adm/api_requirements#api_-_requirements_for_a_system_to_be_connected|here]]

===== Quick explanation of rest api headers to understand filleds in configuration =====

Every request (CRUD) contains these attributes:

  * Accept: application/json
  * login: someUserName
  * password: somePasswd
  * client: someClientNumber
  * businessunit: someBusinessUnit

If request have return body it has one more value:

  * content-type: application/json

===== Quick explanation of rest api returned values from request to understand filleds in configuration =====

Body of sending request (POST):
<code>

{
    "Id": "john.doe",
    "Name": "john",
    "Surname": "doe",
    "Disabled": false,
    "Email": "john@doe.com",
    "Role": "someRole",
    "BusinessUnit": "someBusinessUnit"
}

</code>

Body of update request (PUT):

<code>
{
    "Id": "john.doe",
    "Name": "newJohn",
    "Surname": "newDoe",
    "Disabled": false,
    "Email": "newJohn@newDoe.com"
}

</code>

Get values from api (GET) Api will return body in this format. Attribute names "Id" and "Name" are filled in Configuration **!This example is returned body from rest api!**:

<code>
{
    "Id": "john.doe",
    "Name": "newJohn",
    "Surname": "newDoe",
    "Disabled": false,
    "Email": "newJohn@newDoe.com"
}

</code>

Delete entity (DELETE):

<code>
Is not supported!

</code>

===== Connector configuration =====

Go to **Systems **click **Add**  button set name and block delete operation because delete is not supported. Then click on the **Save and continue **button.

After save go to the **Connector configuration**  set Connector type as DscsConnectorConnector and click it.

Next, fill form for connection to api. Description of values:

  * Url - url where api is accessible
  * Login - user name of account for access will be in header of request
  * Password - password for account for access will be in header of request
  * Client - Identification for client which will be in header
  * Business unit - Identification for business unit which will be in header
  * Name - this field set what attribute in json will be name for entity. In this case it is "Name".
  * Id - this field set what attribute in json will be id for entity. In this case it is "Id".

Example of configuration:

{{.:rest-api:rest-api_1_conconf.png?nolink&1264x968}}

===== Scheme for attributes =====

Generate scheme for mapping attributes with green button **Generate the scheme**  for Synchronization and Provisioning. Type of object scheme is __ACCOUNT__  which is for connection of identities. In loaded attributes i have __NAME__  which is defined by standard but not be used in this case.

Example of __ACCOUNT__  object attributes:

{{.:rest-api:rest-api_2_schemeattr.png?nolink&1470x1002}}

===== Map attributes for synchronization =====

In Mapping you can map loaded attributes from previous step. Firs of all click add button set **Operation type **as **Synchronization**. In **Mapped attributes **click **ADD **and fill map attributes.

For mapping "Id" is example:

{{.:rest-api:rest-api_3_atrmapdet.png?nolink&988x692}}It will connect attributes from json to idm attributes of identity. My mapped attributes for synchronization are these:

{{.:rest-api:rest-api_4_mappatr.png?nolink&828x490}}

Now on **Synchronization tab**  you can **ADD **new task. Check **Reconciliation **checkbox. Fill **Name.**  Choose **Set of mapped attributes**  chose created mapping for synchronization. Finally set **Correlation attribute **typically Id. Click **SAVE AND CONTINUE**. Back to Synchronization tab and click start (green arrow).

===== Provisioning =====

Create mapping for Provisioning in **Mapping**  tab of system. Mapped attributes will be in json body in requests. set **Operation type**  on Provisioning. And connect attributes.

My example:

{{.:rest-api:rest-api_5_mappatr.png?nolink&1600x1076}}
