# Webhooks
_**Note:**
Starting from GitLab 8.5:_
- _the `repository` key is deprecated in favor of the `project` key_
- _the `project.ssh_url` key is deprecated in favor of the `project.git_ssh_url` key_
- _the `project.http_url` key is deprecated in favor of the `project.git_http_url` key_
Project webhooks allow you to trigger an URL if new code is pushed or a new issue is created.
You can configure webhooks to listen for specific events like pushes, issues or merge requests. GitLab will send a POST request with data to the webhook URL.
Webhooks can be used to update an external issue tracker, trigger CI builds, update a backup mirror, or even deploy to your production server.
## SSL Verification
By default, the SSL certificate of the webhook endpoint is verified based on
an internal list of Certificate Authorities,
which means the certificate cannot be self-signed.
You can turn this off in the webhook settings in your GitLab projects.

a comment on a issue will include the specific issue information under the `issue` key.
Valid target types:
1. `commit`
2. `merge_request`
3. `issue`
4. `snippet`

#### Example webhook receiver
If you want to see GitLab's webhooks in action for testing purposes you can use
a simple echo script running in a console session.
Save the following file as `print_http_body.rb`.
```ruby
require 'webrick'
server = WEBrick::HTTPServer.new(:Port => ARGV.first)
server.mount_proc '/' do |req, res|
puts req.body
end
trap 'INT' do
server.shutdown
end
server.start
```
Pick an unused port (e.g. 8000) and start the script: `ruby print_http_body.rb
8000`. Then add your server as a webhook receiver in GitLab as
`http://my.host:8000/`.
When you press 'Test Hook' in GitLab, you should see something like this in the console.
