What's your experience been developing webhook integrations?

I've worked with webhooks my whole career as a software developer but I always had the same problems when consuming them: no centralized management and complex implementations. About 3 years ago I started developing a tool to solve this problem.

After doing an initial release of the tool and getting some feedback, it seems like webhooks are a universal pain.

I'm really interested to hear about other developers experiences working with webhooks. Both on the receiving side and the sending side.

• What pain points do you have when developing a webhook integration?
• What tools do you use to implement a webhook integration?
• How do you ensure you don't lose any webhooks if your site has unexpected downtime?
• What's been your general experience working with webhooks?
