REST Integration Patterns for ServiceNow

ServiceNow provides RESTMessageV2 for outbound REST API calls and the REST API for inbound requests.

Outbound REST (Calling External APIs)

Basic GET Request

var request = new sn_ws.RESTMessageV2()
request.setEndpoint("https://api.example.com/users")
request.setHttpMethod("GET")
request.setRequestHeader("Accept", "application/json")

var response = request.execute()
var httpStatus = response.getStatusCode()
var body = response.getBody()
