That's a good idea, we've been focused on getting up to speed to run your own code (which could just be a lamda uploading to S3, etc.) but directly integrating with some services is definitely possible. We just want to be careful not to become another Zapier, we want to help the tech teams!

When this happens, ping me on twitter! I'll send some customers your way. One of my most frequently asked questions is if I know of an easy way to host webhook handler code. I usually point to Zapier, but I'd rather point to Hookdeck. :)
