the video covers some important aspects of working with outbound REST API calls in ServiceNow. Here’s a concise summary of the key points:
Making Outbound REST API Calls:
Use the RESTMessageV2 API to create and send REST messages from server-side scripts.
Methods like setHttpMethod(), setEndpoint(), and setRequestBody() help configure the request.
Executing the Call:
execute(): Synchronously sends the request and waits for the response.
executeAsync(): Asynchronously sends the request, allowing the script to continue running without waiting for the response.
Parsing the Response:
Use methods like getBody(), getStatusCode(), and getHeaders() to handle the response.
Parse the response body, typically JSON, using JSON.parse() or similar methods.
Best Practices:
Prefer executeAsync() for better performance and to avoid blocking the script.
Handle errors and timeouts appropriately to ensure robust and reliable integrations.
