Sure, you can achieve this by using ServiceNow's REST API. Here's a high-level overview of the steps you would need to follow:

1. Create an endpoint in ServiceNow to receive the JSON request:
- Navigate to System Web Services > Scripted Web Services > New.
- Fill in the necessary fields and write a script to parse the incoming JSON request.

2. Create an Incident record:
- Use the new method of the GlideRecord class to create a new incident record.
- Set the necessary fields using the setValue method.
- Use the insert method to save the new record.

3. Create an Incident Task record:
- Similar to the incident record, use the new method of the GlideRecord class to create a new incident task record.
- Set the necessary fields using the setValue method.
- Use the insert method to save the new record.

Here's a sample code snippet:

javascript
// Parse the incoming JSON request
var requestBody = request.body.data;
var parsedBody = JSON.parse(requestBody);

// Create a new incident record
var incident = new GlideRecord('incident');
incident.initialize();
incident.short_description = parsedBody.short_description;
incident.description = parsedBody.description;
incident.insert();

// Create a new incident task record
var incidentTask = new GlideRecord('incident_task');
incidentTask.initialize();
incidentTask.short_description = parsedBody.task_short_description;
incidentTask.description = parsedBody.task_description;
incidentTask.parent = incident.sys_id; // Link the task to the incident
incidentTask.insert();

Sure, you can achieve this by using ServiceNow's REST API and Scripted REST API. Here's a high-level overview of the steps you need to follow:

1. **Create a Scripted REST API in ServiceNow:**
- Navigate to System Web Services > Scripted REST APIs.
- Click on New to create a new API.
- Provide a name, API ID, and version for your API.
- Click on Submit to create the API.

2. **Create a Resource for the API:**
- Open the API you just created.
- Click on Resources related list and then click on New to create a new resource.
- Provide a name, HTTP method (POST in your case), and script for the resource.
- In the script, you need to parse the incoming JSON request and create an incident and incident task using GlideRecord.

3. **Sample Script for the Resource:**
- Here's a sample script that creates an incident and incident task based on the incoming JSON request:

javascript
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
var data = request.body.data;
var grIncident = new GlideRecord('incident');
grIncident.initialize();
grIncident.short_description = data.short_description;
grIncident.description = data.description;
grIncident.insert();
var grIncidentTask = new GlideRecord('incident_task');
grIncidentTask.initialize();
grIncidentTask.short_description = data.task_short_description;
grIncidentTask.description = data.task_description;
grIncidentTask.parent = grIncident.sys_id;
grIncidentTask.insert();
})(request, response);

4. **Test the API:**
- You can test the API using any API testing tool like Postman.
- Send a POST request to the API endpoint with the JSON body containing the details of the incident and incident task.

5. **Handle Errors:**
- Make sure to handle any errors that might occur during the creation of the incident and incident task.
- You can use try-catch blocks in your script to handle errors.

Remember to replace the field names in the script with the actual field names in your incident and incident task tables.

Hi @Ketan Pandey 

Do you have a pre-defined JSON response to be received by the ServiceNow instance or an external system will make a REST Call towards the ServiceNow instance ?

Thanks & Regards

Hi Amit,

Thank you for your response.

Here in my case ,External system will make the REST call
