Recommended way to implement asynchronous outbound REST call with MID Server

I am creating the workflow implementing Outbound REST call with MID Server and would like this call be truly asynchronouse(means the workflow will exit without waiting a reply from the REST call).

According to the article below, It seems possible to implement this requirement using the ServiceNow's "Discovery probe and sensor" feature. (final example in the article)

My question is regarding this solution. Do you think it is a recommended way to implement truly asynchronous?

I understand the "Discovery probe and sensor" feature is for finding an IT resources in the environment to manage and not for creating a custom logic like business rule or workflow. so I feel this solution might be too tricky to use in production environment.

Please give me your comment about this. and if you have more sophisticated way to implement truly asynchronous, please let me know.

Thanks in advance.
