Excellent product. Basically, they provide all the features that you need to implement webhooks that will be consumed by your SaaS clients. Personally, my favorite feature is the webhook log on self-serving user dashboard. It saves a ton of time on support because users can see why exactly the webhook did or didn't work themselves.

The docs for non-standard cases is very poor, and Python SDK has some weird quirks. For example, for some reason you have to use different methods to get user info depending on how user registered (via email or via google oauth). However, basic cases on frontend are super-easy to implement.
