Configuring Service Catalog Requests

Once you connect EmpowerID to ServiceNow, your ServiceNow developers can configure ServiceNow to create EmpowerID objects via service catalog requests. This topic demonstrates how to configure ServiceNow to add an EmpowerID group service catalog request.

In ServiceNow, you need to create the following, all of which are covered in this topic.

• An OAuth provider that contains the information needed to connect with EmpowerID so that REST messages can be passed.
• Two new properties in the Request [sc_request] table to use in the Resume HTTP method of the REST message.
  • workflowinstanceid
  • workflowcorrelationid
• A REST message that calls the EmpowerID REST API with three POST HTTP methods.
  • Default POST: for starting the workflow on the ServiceNow side
  • Access Token: to get an access token for web API calls
  • Resume Workflow POST: for starting the workflow on the EmpowerID side
• A Business Rule on the Approval table that tracks EmpowerID group requests in the Approval table, and passes values to the REST message.
• A ServiceNow workflow to handle user requests from the service catalog.
• A service catalog request so users can request EmpowerID groups through ServiceNow.

To create an OAuth provider

The OAuth provider contains the information needed to connect with EmpowerID so that REST messages can be passed.

1. Log in to your ServiceNow instance, and in the navigation pane, search for Application Registry and select it.
   
   
   
   
2. Above the list of Application Registries, click the New button, and select Connect to a third party OAuth Provider.
   
   
   
   
3. Configure the new Application Registry with the following settings. (Skipped settings retain their default values.)
   
   • Name - EID

   • Client ID - The GUID from your EmpowerID OAuth application Client ID (Key)

     To find your EmpowerID OAuth settings in the web UI, expand Admin, then SSO Connections, and click OAuth. You can find all of the client settings in the DefaultEmpowerIDOauthApplication.

   • Client Secret - The GUID from your EmpowerID OAuth application Client Secret
   • OAuth API Script - Click the search icon and select OAuthUtil.
   • Authorization URL - https://FQDN/oauth/v2/ui/authorize
     Replace "FQDN" with the fully qualified domain name of your EmpowerID server (e.g. sso.empoweriam.com).
   • Token URL - https://FQDN/oauth/v2/token
   • Redirect URL - https://FQDN/WebIdPForms/oauth/v2
     
     
     
     
4.  Scroll to the bottom, and on the OAuth Entity Profiles tab, double-click the text Insert a new row and enter these values.
   • Name - EID default_profile
   • Is default - true
   • Grant type - Resource Owner Password Credentials
     
     
5. Click Submit to save the OAuth provider.

To add new columns to the Request table

Add two columns to the ServiceNow Request table to use in the Resume HTTP method parameters. The Resume method collects these values, along with the IsApproved value, via the HTTP query parameter script to pass to EmpowerID.

1. Log in to your ServiceNow instance, and in the navigation pane, search for Tables and select the one under System Definition.
   
   
   
   
2. Above the list of Tables, change the Go to drop-down from Name to Label, and search for Request.
   
   
   
   
3. Click the Request [sc_request] table.
4. On the Columns tab, click the New button to add a new Correlation ID column with the following settings. (Skipped settings can retain their default values.)
   • Type - String
   • Column label - Correlation ID
   • Column name - (autofills after a pause) u_correlation_id
   • Max length - 255
   • Active - selected
   • Display - selected
     
     
5. Click Submit to save the new column.
6. Back on the Columns tab, click the New button to add a new Workflow Instance ID column with the following settings. (Skipped settings can retain their default values.)
   • Type - String
   • Column label - Workflow Instance ID
   • Column name - (autofills after a pause) u_workflow_instance_id
   • Max length - 255
   • Active - selected
     
     
7. Click Submit to save the new column.
8. Back on the Request table, click Update to save the new columns to the Request table.

To create a REST message

The REST message is what passes information between ServiceNow and the EmpowerID REST API. It uses three methods to communicate via EmpowerID's anonymous endpoints. One method passes access tokens, another responds to group requests created in EmpowerID with approval or rejection, and the third notifies EmpowerID to create a group from a request in the ServiceNow services catalog.

1. In the navigation pane, search for REST Message and select it.
   
   
   
   
2. Above the list of REST Messages, click the New button.
   
   
   
   
3. Configure the new REST message with the following settings.
   • Name: EmpowerID API 
     Take note of the name you use, as it is used in the Creating an Approval Business Rule script below.
   • Accessible from - All application scopes
   • Endpoint - https://FQDN/oauth/v2/token 
     Replace "FQDN" with the fully qualified domain name of your EmpowerID server (e.g. sso.empoweriam.com).
     
4. On the Authentication tab:
   • Change the Authentication type to OAuth 2.0.
   • For the OAuth profile, click the search icon and select the EID default_profile that you created earlier.
     
     
     
     
5. On the HTTP Request tab, add two HTTP Headers.
   
   
   
   
   1. In the list of HTTP Headers, double-click the text Insert a new row and enter these values.
      • Name - Content-Type
      • Value - application/json
        
        
   2. Insert another new row and enter these values.
      • Name - X-EmpowerID-API-Key

      • Value - your EmpowerID OAuth application API key
        
        

        You can find your OAuth application API key in EmpowerID by expanding Admin, then SSO Connections,and selecting OAuth. Click to open the DefaultSystemOAuthApplication (not the same as the one with the OAuth client keys), then click the Display Name to open it for editing. There you can copy the API Key for use in ServiceNow.

6. Click Submit to save the REST message. Back on the REST Messages list, click your newly created EmpowerID API REST message. A message at the top directs you to click the Get OAuth Token link to request a token.

7. Click the link, supply your EmpowerID admin username and password, and click Get OAuth Token.

   If you are testing this in a lab setting, be sure to make your machine URL public so that ServiceNow can find it, and be sure that the same FQDN is in EmpowerID configurator for the web server and CDN server.

8. Back on the EmpowerID API message, scroll to the bottom to see the HTTP Methods list.
   
   
   
   

9. Next to HTTP Methods, click the New button to create a new POST method. Create three in total, with the following settings. (Click Submit after each to return to the main REST Message page where you can add the next.)
   
   

   
10. Click the Submit (or Update) button to save the REST message.

To create an Approval business rule

The Approval table, where ServiceNow tracks EmpowerID group approval requests and their results, needs a business rule to pass values to the REST message.

1. Log in to your ServiceNow instance, and in the navigation pane, scroll down and expand System Definition, then find and select Business Rules. (You can also search for Business Rules, and select the one nested under System Definition.)
   
   
   
   
2. Above the list of Business Rules, click the New button, and add a new one named EmpowerID BR.
   
   
   
   
3. Configure the new business rule with the following settings.
   • Name - EmpowerID BR
   • Application - Global (default)
   • Table - Approval [sysapproval_approver]
   • Active - selected (default)
   • Advanced - selected (shows an advanced tab below, and adds fields)
     
     
4. On the When to run tab, set When to "after," and select the Update checkbox.

5. On the Advanced tab, paste this script to replace the default stub.
   
   

   (function executeRule(current, previous /*null when async*/) {
       
           // Code to create response for EmpowerID and update the Approval table
       try
           {
               var r = new sn_ws.RESTMessageV2("EmpowerID API", "Access Token");
               var response = r.execute();
               var responseBody = response.getBody();
               var parser = new JSONParser();
               var parsed = parser.parse(responseBody);
               var t = parsed.access_token;
               
               var regRecord = current.document_id.getRefRecord();
               if(regRecord.getValue('u_workflow_instance_id') != null)
               {
                   var r1 = new sn_ws.RESTMessageV2("EmpowerID API", "Resume");
                   r1.setStringParameterNoEscape("Token", t);
                   r1.setStringParameterNoEscape("WorkflowInstanceID", regRecord.getValue('u_workflow_instance_id'));
                   r1.setStringParameterNoEscape("CorrelationId", regRecord.getValue('u_correlation_id'));
                   r1.setStringParameterNoEscape("IsApproved", current.state);
                   var response1 = r1.execute();
                   var responseBody1 = response1.getBody();
                   var httpStatus1 = response1.getStatusCode();
               }
               else
               {
                   var req_item = new GlideRecord('sc_req_item');
                   req_item.addQuery('request', regRecord.sys_id);
                   req_item.query();
                   if(req_item.next())
                   {  		
                       var r2 = new sn_ws.RESTMessageV2("EmpowerID API", "Default POST");
                       r2.setStringParameterNoEscape("Token", t);
                       r2.setStringParameterNoEscape("Name", req_item.variables["group_name"].toString());
                       r2.setStringParameterNoEscape("Description", req_item.variables["group_description"].toString());
                       r2.setStringParameterNoEscape("Decision", current.state);
                       var response2= r2.execute();
                       var responseBody2= response2.getBody();
                       var httpStatus2 = response2.getStatusCode();
                   }
               }
           }
           catch(ex) 
           {
               var message = ex.getMessage();
           } 
       
       })(current, previous);
                       

6. Click Submit to save the business rule.
