Hi @Ketan Pandey 

Thank you for the clarification. You can make use of ServiceNow Table REST API to create incident and incident task. Please refer below link for creating incident using REST API explorer.

https://docs.servicenow.com/bundle/tokyo-application-development/page/integrate/inbound-rest/task/t_...

For creating Incident task, make use of Table API only in REST API explorer on the table "incident_task". Please refer below snip. Here, in the incident, pass the value of the sys_id of the incident created in the previous REST API call.

Thanks & Regards

As a ServiceNow expert, I can tell you that ServiceNow can both send and receive RESTful API calls. However, the structure of the JSON response or request is not predefined and depends on the specific API endpoint and the data being sent or requested.

Here are the steps to set up a RESTful API in ServiceNow:

1. Navigate to System Web Services > Outbound > REST Message.
2. Click New to create a new REST message.
3. Fill in the fields, such as Name, Endpoint, HTTP Method, etc.
4. You can add parameters to the HTTP request in the HTTP Request tab.
5. You can also add or modify the HTTP headers in the HTTP Headers tab.
6. In the content tab, you can define the body of the request. If you're sending a JSON payload, you can define it here.
7. Once you've set up the REST message, you can use the 'Test' related link to send a test request.

Here's a sample script to send a RESTful API call from ServiceNow:

javascript
var restMessage = new sn_ws.RESTMessageV2('YOUR_REST_MESSAGE', 'DEFAULT_HTTP_METHOD');
restMessage.setStringParameterNoEscape('parameter1', 'value1');
restMessage.setStringParameterNoEscape('parameter2', 'value2');
var response = restMessage.execute();
var responseBody = response.getBody();
var httpStatus = response.getStatusCode();

To receive a RESTful API call in ServiceNow, you need to create a Scripted REST API. Here are the steps:

1. Navigate to System Web Services > Inbound > Scripted REST APIs.
2. Click New to create a new Scripted REST API.
3. Fill in the fields, such as Name, API ID, etc.
4. Click Submit to create the API.
5. Now you can add resources to the API. Each resource corresponds to a specific URL and HTTP method.
6. For each resource, you can define a script to process the request and send a response.

Here's a sample script to process a RESTful API call in ServiceNow:

javascript
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
var body = request.body.data;
var parameter1 = body.parameter1;
var parameter2 = body.parameter2;
// process the parameters and perform some action
response.setStatus(200);
response.setBody({
result: 'Success'
});
})(request, response);

Remember to replace 'YOUR_REST_MESSAGE', 'DEFAULT_HTTP_METHOD', 'parameter1', 'value1', 'parameter2', 'value2' with your actual REST message name, HTTP method, and parameters.
