Can anyone please explain below question with simple examples:-

-Scripted REST API

-REST 

*REST API Explorer

- API

- Outbound*REST Message

- Inbound and outbound Integration
and please provide you tube links related to integration to start  from basics.

Thanks 😉

Hello @b__HanumeshM,

Please find the below data and let me know whether it is useful or not.

1. Scripted REST API:

In ServiceNow, a scripted REST API allows developers to create custom endpoints that can receive and send data using HTTP methods (GET, POST, PUT, DELETE).

https://docs.servicenow.com/bundle/xanadu-api-reference/page/integrate/custom-web-services/concept/c...

Example: You can create a Scripted REST API to fetch incident details. When a user sends a GET request with an incident number, the scripted REST API will return incident details in JSON format.

(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {

    var incidentNumber = request.queryParams.incident;

    var gr = new GlideRecord('incident');

    gr.get('number', incidentNumber);

    response.setBody(gr);

})(request, response);

2. REST:

REST (Representational State Transfer) is a set of principles for designing networked applications, allowing for communication between systems via HTTP.

https://docs.servicenow.com/bundle/utah-api-reference/page/integrate/inbound-rest/concept/c_RESTAPI_...

Example: In ServiceNow, you can call an external system's REST API using the REST Message functionality to send data or retrieve information.

3. REST API Explorer:

This is a tool within ServiceNow that allows you to quickly test REST endpoints by sending requests to ServiceNow or other systems.

https://developer.servicenow.com/dev.do#!/learn/learning-plans/washingtondc/servicenow_application_d...

Example: If you want to test the incident retrieval API, you can input the incident number and use GET in the REST API Explorer to check the response.

4. API:

API (Application Programming Interface) is a broader concept that refers to a set of rules that allows one software application to interact with another.

https://developer.servicenow.com/dev.do#!/learn/learning-plans/xanadu/new_to_servicenow/app_store_le...

Example: ServiceNow provides various APIs like the GlideRecord API to interact with its database and perform CRUD (Create, Read, Update, Delete) operations.

5. Outbound REST Message:

This is a message sent from ServiceNow to an external system using the REST protocol.

https://developer.servicenow.com/dev.do#!/learn/learning-plans/washingtondc/servicenow_application_d...

Example: If you want to send data from ServiceNow to an external CRM system, you would configure an outbound REST message to send the data, such as customer information, from a ServiceNow form to the CRM system.

var restMessage = new sn_ws.RESTMessageV2('External System', 'POST');

restMessage.setStringParameterNoEscape('name', 'Customer Name');

var response = restMessage.execute();

6. Inbound and Outbound Integration:

Inbound Integration refers to data coming into ServiceNow from an external system.

Outbound Integration refers to data being sent from ServiceNow to an external system.

https://docs.servicenow.com/bundle/washingtondc-financial-services-operations/page/product/fso-commo...

Example: Inbound - an external system sends a ticket update via REST to ServiceNow. Outbound - ServiceNow sends incident creation data to an external monitoring tool.

Thanks
