Execute the request asynchronously

Member of HTTP Request (PRIM_WEB.HttpRequest)

Details

The ExecuteAsync method is used to execute the HTTPRequest asynchronously.
 
Once the request is submitted, processing will continue, ensuring that user interaction isn't blocked.
 
The use of asynchronous requests is recommended over synchronous requests.

Example

In this example, a weather API is executed asynchronously, returning the data as a JSON object.
 
When the completed event fires, the result is processed.
