Posting works well for making outbound HTTP requests; the only part it doesn't handle by default is locally capturing and replaying webhooks.

While testing TradingView alerts, exchange execution callback handlers, or cryptocurrency payment webhooks for our trading software, we always find ourselves running `posting` (or `curl`) in one terminal window while having an additional tunneling/receiving script running in another one just to catch and retransmit the tricky JSON payloads.
