ServiceNow Integration
ServiceNow integration is supported with basic authentication or OAuth. The user will need enough permissions to create change requests.

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:
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 defaultTICKET.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 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 ticketimport 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();

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:
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 defaultExample that checks myfield value specific to target environment |
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:
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. |

Configure Folder for Change Management Approvals
Configure ServiceNow Change Management Instance on your parent folder. Change management configurations are inherited by sub-folder and projects. This configuration will allow you to integrate ServiceNow tickets with your FlexDeploy deployment. See https://flexagon.atlassian.net/wiki/spaces/FD65/pages/10125813042 for more details.
Linking ServiceNow with FlexDeploy Deployments
If Auto Create Ticket, is not enabled, then user must specific the change ticket number on the deployment request. See . Otherwise, Change Ticket field will be required in the deployment request form. When change ticket number is passed the ticket number is validated on the external application.
