Receive Transaction Responses Asynchronously {#sis-pymnt-svcs-cloud-txn-resp-async-api-task}
============================================================================================

Asynchronous endpoints can be used to receive transaction responses for most types of transaction requests when the app is in Cloud mode.  
Follow these steps to receive transaction responses asynchronously:

1. Use the asynchronous endpoints shown in the example to process a transaction and receive an interaction identifier. The example shows how to process a sale asynchronously.
2. After the transaction is completed, use the interaction identifier returned in the response to check the transaction events and to get a transaction identifier.
3. Use the transaction identifier to process a Check Transaction Status request. The response will contain full transaction and receipt details. For more information, see [Requesting a Check Transaction Status](/docs/cybs/en-us/sis-pax/integration/all/rest/sis-pax/sis-pymnt-svcs-cloud-mode-intro/sis-pymnt-svcs-cloud-txn-status-api-intro.md "").
