Asynchronous calls

REST calls made to Cloud API are typically synchronous. The caller application submits a call and then waits for the reply. However, for some types of calls, waiting for a reply may be problematic. For example:

• The call may take long enough to process that the API Gateway times out.
• The call may take long enough to process that the client-side toolkit used to make the call times out.
• A synchronous call may consume too many client-side resources.

To address these situations, calls can also be made asynchronously. The caller application submits the request at one point in time. At a later point in time, the caller application retrieves the response.

This topic discusses how to execute Cloud API calls asynchronously.
