Use Case - Creating an Incident Task in ServiceNow

We want to create an incident Record in ServiceNow based on the information the caller gives us.

The flow is as follows:

A caller calls the IT Helpdesk Number.
In the Nimbus workflow, there is a "Customer Input" element asking whether the caller wants to get help from an agent or if he wants to report an incident.
If the caller chooses the incident report, we save the decision into a Parameter.
The Power Automate flow starts with an "OnUpdatedTask" Session Event item and checks on the "ParameterUpdated" Trigger Event. If the parameter is “report incident”, then the flow is triggered.

You have a Power Automate Premium subscription for the "Service Now" connector element.
You have a service Now connection. Alternatively, a dev box as described below.
If you have a running ServiceNow instance to test your flow on, you can go directly to Step 3.

💡 = A hint to signal learnings, improvements, or useful information in context.	🔍 = Points out essential notes or a related page in context.
☝ = Notifies you about fallacies and tricky parts to help avoid problems.	🤔 = Asks and answers common questions and troubleshooting points.
❌ = Warns you of actions with irreversible/data-destructive consequence.	✅ = Instructs you to perform a certain (prerequired) action to complete a related step.

Go to the instructions on how to obtain a Personal Developer Instance (PDI) and create your instance.
✅ Note down the connection details for later!
Check that in. In ServiceNow, the status of your instance should show "Online".
Open and log in to your box.
Find the Incidents table and open it.
Find the user who has read/write permissions on it (per default Incident.Manager).

You can always view connection credentials in My Instance ->"Manage instance password".
If you don’t use your instance for more than 10 days, ServiceNow will back it up. Recovery might take very long or cause errors, so we recommend creating a fresh one if you need to test again.

🔍 In PowerAutomate, we can evaluate the choice of the "Collect Information" workflow activity and create a ServiceNow ticket accordingly.

In this example, we store the input in a Parameter called (CustomerChoice).
For ServiceNow and the Flow, we also need to create the parameter in Configuration -> Parameters -> Create new.
1. ServiceNowUrl
2. ServiceNowTicket
3. ServiceNowSysId

We start with "When a task changes stage" trigger element and want to listen to the "Parameter Updated" event.
Add a ServiceNow element to the flow and connect to it with a user that has permissions to read and write to it.
Rename it to “Add Incident”
Add the values
- Short description = Incident via Nimbus triggerOutputs()?['body/teamName']
- Correlation display= triggerOutputs()?['body/id']
- Actual start = triggerOutputs()?['body/created']
- Contact type = triggerOutputs()?['body/customer/displayName']
Add a Nimbus UpdateTask element and map the corresponding fields
1. CustomContextParameters Name= ServiceNowUrl value= concat('https://dev123456.service-now.com/nav_to.do?uri=incident.do?sys_id=', outputs('Add_Incident')?['body/result/sys_id'])
  ✅ Adapt the URL according to your connection details above.
2. Customer.CustomFields Name = ServiceNowSysId value= outputs('Add_Incident')?['body/result/sys_id']
3. Customer.CustomFields Name = ServiceNowTicket value= outputs('Add_Incident')?['body/result/number']
