Cofounder of QuikNode.io here - this is kind of a “it depends” question/answer. What chain are you using? Ethereum? Bitcoin? EOS? At a high level you could encrypt the data (URL) you want to send the webhook to, then (let’s say you’re using Ethereum) you could subscribe to an event & make sure you have the decryption key there to decrypt the URL & actually forward on the webhook. In terms of the user auth question, you can use signed requests or just signatures in general - I love the localcryptos.com implementation of user login, for instance. Happy to answer more questions like this, just email me: auston@quiknode
