Differences Between Synchronous and Asynchronous Integrations

An application integration can be synchronous or asynchronous. Synchronous and asynchronous integrations have some key differences, including whether they provide an immediate response.

Question	Synchronous integration	Asynchronous integration
Optimal use	Best for delivering real-time information	Best for performing work in batch operations
Response	Oracle Integration sends a response after the integration finishes running, so you know the integration succeeded	Oracle Integration sends a response immediately after receiving the request, so you know Oracle Integration received the request The response is an HTTP 202 Accepted message You don't receive a response when the integration finishes running unless you configure an invoke to provide a notification
Run timing	The integration runs immediately	Oracle Integration places the integration in a queue
Payload	The response includes a payload	The response doesn't include a payload
Guaranteed delivery of requests	The integration doesn't guarantee the delivery of its requests	The integration guarantees delivery of its requests
Long-running tasks	The integration cannot perform long-running tasks	The integration can perform long-running tasks
Subscribe to events	The integration cannot subscribe to events	The integration can subscribe to events
Rerun after failure	You cannot rerun the integration if it fails	You can rerun the integration if it fails
