webhook is a lightweight configurable tool written in Go, that allows
you to easily create HTTP endpoints (hooks) on your server, which you
can use to execute configured commands. You can also pass data from
the HTTP request (such as headers, payload or query variables) to your
commands. webhook also allows you to specify rules which have to be
satisfied in order for the hook to be triggered.

For example, if you're using Github or Bitbucket, you can use webhook
to set up a hook that runs a redeploy script for your project on your
staging server, whenever you push changes to the master branch of your
project.

If you use Mattermost or Slack, you can set up an "Outgoing webhook
integration" or "Slash command" to run various commands on your
server, which can then report back directly to you or your channels
using the "Incoming webhook integrations", or the appropriate response
body.

webhook aims to do nothing more than it should do, and that is:
1. receive the request,
2. parse the headers, payload and query variables,
3. check if the specified rules for the hook are satisfied,
4. and finally, pass the specified arguments to the specified command
   via command line arguments or via environment variables.

Everything else is the responsibility of the command's author.
