* Synchronous API Operations: * Immediate Response: In a synchronous operation, the client sends a request to the server and waits for an immediate response. The client cannot proceed until it receives this response. * Blocking Call: The call is considered blocking, meaning the client application is blocked from performing other tasks until the response is received. * Use Case: This is useful when the result of the operation is required immediately to continue the workflow. * Asynchronous API Operations: * Delayed Response: In an asynchronous operation, the client sends a request to the server and does not wait for an immediate response. Instead, it continues its processing and can check back later for the result. * Non-blocking Call: The call is non-blocking, allowing the client to perform other tasks while waiting for the server to complete the operation. * Polling and Webhooks: Clients may poll the server for status updates or subscribe to a webhook to be notified when the operation is complete. * Task ID: The server may provide a task ID in the response that can be used to check the status of the operation later.
