CM Webhooks is a way to implement webhooks for the events generated by your different projects in Vercel.
Currently, there is no way to directly configure events generated by your projects to be sent to a URL controlled by you. The only way this is possible is for you to create an integration and that integration will manage this process for you.
To avoid everything involved in developing an integration for Vercel, testing and maintaining the code of that software, CM Webhook was created. Like you, I also had this same need that is already offered by other services such as Heroku or Netlify.
This is an integration that is completely free, so you will not have to worry about additional expenses in your projects. In addition, the entire infrastructure of this application is also deployed in Vercel, in such a way that we make the most of all the benefits that this service offers us.
This documentation is super easy to understand, so it is not at all complicated to follow the step by step of each of the sections. I will try as much as possible to be very clear in each of the concepts and parts of this documentation, and if you have questions you can contact the support email: firstname.lastname@example.org
