single API call to receive all deployed systems info

Indeed, this API creates an operation. The operation will be executed. You can use two ways: in the export API you can define a callback to be called when the operation state changed and so get operation uuid in order to get the file URL. See Operations section, for Operations API: doc.airvantage.net/av/reference … ration-v1/
The API you have to call is /v1/operations/{uid}/result in order to download the file.

You can poll the operation detail until the operation is success.
