ServiceNow Request GET URL

SN_REQUEST_GET_URL

No

The URL to get the change request details as json response.

Default URL is /api/now/table/change_request?sysparm_query=number%3D{SN_CHANGE_NUMBER}
If needed, you can change and use your custom GET url for ServiceNow REST endpoint. The URL should include {SN_CHANGE_NUMBER} string as the execution system will replace it with the actual change number during execution.
- e.g. /api/xyz/mycompanty_servicenow_generic_api/readChangeRequest?number%3{SN_CHANGE_NUMBER}
If the response returned from this GET API contains an attribute called description it will be mapped to the description of the linked ticket, otherwise the description on the links tab will appear as empty. Prior to 5.5.0.2, an error would occur if the description field was not present in the payload returned from this GET API.

ServiceNow Navigation Request URL

- e.g. https://<instance name>.service-now.com/nav_to.do?uri=change_request.do?sysparm_query%3Dnumber%3DCHG0080007
- e.g., if you want to use Service Catalog, url will be like

Approved Check Script

SN_APPROVED_SCRIPT

No

A Groovy expressions which determines whether a task for the change ticket is approved or not. The expression must return a boolean, and has access to the following variables:

TICKET - an object with fields (JSON) contained in the change ticket, as returned by the ServiceNow REST API. Fields are referenced as TICKET.<field name>.<sub-field name>
FD_ENVIRONMENT_CODE - The environment for a particular deployment request or associated pipeline stage.

Info
If the Approved Check Script is left blank, the default implementation is to return true if the "approval" field of the ticket is set to "approved".

Simple Example which is used by default

Code Block

language	groovy

TICKET.approval == 'approved'

Example that checks myfield value specific to target environment

Code Block

language	groovy

(TICKET.myfield == 'UATApproved' && FD_ENVIRONMENT_CODE='UAT') || (TICKET.myfield == 'PRODApproved' && FD_ENVIRONMENT_CODE='PROD')

Tip
If you want to see values that can be used, enable `FINEST` log level for `flexagon.fd.model.integration.cms.`CMSScript using Admin Operations.

Following example is to check if current date time is between start_date and end_date defined on Ticket. Let's assume format for the date string returned and TimeZone as GMT.

Check if now is between start_date and end_date defined on ticket

Code Block

language	groovy

import java.util.Date;
import java.util.TimeZone;
import flexagon.ff.common.core.utils.FlexDateTimeUtils;

if(TICKET.approval == 'approved' && TICKET.start_date != null && TICKET.end_date != null)
{
    Date start = FlexDateTimeUtils.stringToDate(TICKET.start_date, "yyyy-MM-dd HH:mm:ss", TimeZone.getTimeZone("GMT"));
    Date end = FlexDateTimeUtils.stringToDate(TICKET.end_date, "yyyy-MM-dd HH:mm:ss", TimeZone.getTimeZone("GMT"));
    Date now = new Date();
    if(now.after(start) && now.before(end))
    {
      return true;
    }
}
return false;

Rejected Check Script

SN_REJECTED_SCRIPT

No

A Groovy expressions which determines whether a task for a change ticket is rejected or not. The expression must return a boolean, and as has access to the following variables:

TICKET - an object with fields (JSON) contained in the change ticket, as returned by the ServiceNow REST API. Fields are referenced as TICKET.<field name>.<sub-field name>
FD_ENVIRONMENT_CODE - The environment for a particular deployment request or associated pipeline stage.

Info
If the Rejected Check Script is left blank, the default implementation is to return true if the "approval" field of the ticket is set to "rejected".

Simple Example which is used by default

Code Block

language	groovy

TICKET.approval == 'rejected'

Example that checks myfield value specific to target environment

Code Block

language	groovy

(TICKET.myfield == 'UATRejected' && FD_ENVIRONMENT_CODE='UAT') || (TICKET.myfield == 'PRODRejected' && FD_ENVIRONMENT_CODE='PROD')

Additional Info Script

SN_ADDITIONAL_INFO_SCRIPT

No

A Groovy expression which determines additional information to add to an external approval when it is approved or rejected. The expression must return a Map<String, String> and have an entry with the key of "notes" for the value to get added to external approval as a task note. Script has access to the following variables:

TICKET - an object with fields (JSON) contained in the change ticket, as returned by the ServiceNow REST API. Fields are referenced as TICKET.<field name>.<sub-field name>
FD_ENVIRONMENT_CODE - The environment for a particular deployment request or associated pipeline stage.

Example where ServiceNow Approver(s) and time of approval are added to task notes

Don't Poll

SN_DONT_POLL

No

Returns whether FlexDeploy should poll ServiceNow to check the change tickets for Approval/Rejection. The default value is false, which means polling will occur. Only check this box if you are using the FlexDeploy REST API to communicate ticket approval/rejection.

Info

ServiceNow Modules

Most common usage for ServiceNow is using the change request module, but other objects like service catalog request can be used by modifying the default GET, POST, and Nav URLs. If you plan to use a different module, for POST operation, use the tickets tab in the CMS configuration screen to add any additional fields required to create the object.

ServiceNow Available TICKET Variables

Within the script properties on the ServiceNow Instance. The following values are available to you via the TICKET object to use in your script logic. For example, TICKET.approval would return the approval value of the ServiceNow change.
