Please do test od the order is being queued in case of offline mode / no network connectivity.

Please do also check what’s happening with the directOrsers mode is off (so when by default order is being queued); in that case we should probably remove it from the queue in case of wrong HTTP status

Please remember to update the vs-api and to try checking the response codes because as you wrote in the issue: 500 error / like a database error /
Whatever is a different story than Magento2 api error (in this case 99% is a validation issue)

@AndreiBelokopytov how about the proposed changes?

Hi @pkarw. I will take a look at it one of these days

@AndreiBelokopytov if you don't mind I'll fix it myself because we really need it in 1.9 and I'd like to fix the old notification instead of introducing some new code.
