RequestBin isn&#x27;t a substitute for HttpBin, they do 2 completely different things:<p>RequestBin = easily provision a url (useful for configuring a webhook) and inspect requests to that url.<p>HttpBin = pre-defined urls that return specific responses (headers &amp; payloads). Good for testing http clients.<p>Fun fact: both tools are operated by the awesome people at <a href="http:&#x2F;&#x2F;Runscope.com" rel="nofollow">http:&#x2F;&#x2F;Runscope.com</a>.
