StaffConditional GO TO step is good but it is limited to XML responses and also has a couple of other limitation. We have specific steps for Asynchronous calls which can actually wait until something is triggered to further validate the responses once the process is finished. Here are some links to the steps that may help you.
File Wait (waits for a file to appear in your local directory and then continues with the next steps in the testcase):

REST VirtResponse(opens a listener on an endpoint:port and waits for a message to come through and then continues with the next steps in the testcase):

Property Wait(Waits for a property in any location of your choice and once it appears the next steps in the testCase will be executed):

There might be couple of other ways you can deal with async calls but I hope this helps.
