ServiceNow Request GET URLString

The URL to get the change object details as json response.   @Since 5.4.0.1

  • 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}
ServiceNow Navigation Request URLString

The URL to open ServiceNow and navigate to the Change ticket associated to the project workflow execution @Since 5.4.0.3

ServiceNow Request POST URLString

The URL to create a change object.   @Since 5.4.0.3

  • Default URL is /api/now/table/change_request
  • If needed you can change and use your custom url to create a new change using the POST operation
    • if you want to use Service Catalog, then change the url to /api/now/table/sc_request

Approved Check Script

String

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.

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
TICKET.approval == 'approved'
Example that checks myfield value specific to target environment
(TICKET.myfield == 'UATApproved' && FD_ENVIRONMENT_CODE='UAT') || (TICKET.myfield == 'PRODApproved' && FD_ENVIRONMENT_CODE='PROD')

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
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 ScriptString

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.

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
TICKET.approval == 'rejected'
Example that checks myfield value specific to target environment
(TICKET.myfield == 'UATRejected' && FD_ENVIRONMENT_CODE='UAT') || (TICKET.myfield == 'PRODRejected' && FD_ENVIRONMENT_CODE='PROD')
Don't PollBooleanReturns 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 is used to communicate ticket approval/rejection.

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.
