I hacked Gumroad’s API and broke a bunch of tools
Huh. So gumroad verification is a simple call to the verify endpoint and I&#x27;m guessing if it returns &quot;success&quot;: true that&#x27;s good enough to enable usage of the product?<p>I guess it would be an interesting experiment to create a proxy that captures any values going out to gumroad&#x27;s license verification api endpoint and change all server responses to be true instead of false. Ditto for altering the number of uses of a product in case there is a limit there too.<p>For anyone interested in the documentation: <a href="https:&#x2F;&#x2F;app.gumroad.com&#x2F;api#licenses" rel="nofollow">https:&#x2F;&#x2F;app.gumroad.com&#x2F;api#licenses</a><p>Also for anyone who is new to this topic, intercepting and altering server responses can yield fascinating results in today&#x27;s client side heavy code web apps.
