Synchronous API calls are blocking, meaning they hold up code execution until a response is returned from the server. This can lead to perceived latency or performance lag in an application if not managed properly. In contrast, asynchronous API calls do not block code execution; they allow the program to continue running and handle the response once it’s available, typically through a callback function

Cisco Intersight REST API requires a secure authentication process that involves creating a SHA256 hash of the message body and headers. This ensures that the message integrity is maintained and verifies that the message has not been tampered with during transit. Even if the message body is empty, a SHA256 hash is still required. Additionally, the use of RSA private keys enhances security, but the specific key size requirement was not mentioned in the provided resources6
