Looking at this, I can't seem to find any examples of Wiremock being used to test async callbacks, which is one of the more challenging things to get right. Can anyone point to some documentation or code samples showing how to do this in Wiremock?

If by async callbacks you mean something akin to webhooks, then there's an extension for that: https://github.com/wiremock/wiremock-webhooks-extension
