Requests to White Server
There are 2 types of requests in WhiteServer:
- synchronous — the response is returned immediately
- asynchronous — the request is sent to the restaurant, and the response is returned to the address specified in the request in the callback field.
You can read more about synchronous and asynchronous requests in the article synchronous and asynchronous requests.
If you plan to use asynchronous requests with a returned callback, you need to configure an external service accessible to White Server and specify its address in the callback field in the request.
