Most of the time request bodies do not get logged, because they often contain sensitive information.

The logging in ngrok also comes with a "replay request" button, which is very nice when you're testing webhooks that are a pain to fire.

It logs the headers and request body along with the response for every single route. This means if the server sending you a webhook changes routes, or sends some extra content or does something unexpected, you have immediate visibility into it and can replay the request with a single click.

Pretty nifty.
