# 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.

## Webhook endpoint tips

If you are writing your own endpoint (web server) that will receive
GitLab webhooks keep in mind the following things:

-   Your endpoint should send its HTTP response as fast as possible. If
    you wait too long, GitLab may decide the hook failed and retry it.
-   Your endpoint should ALWAYS return a valid HTTP response. If you do
    not do this then GitLab will think the hook failed and retry it.
    Most HTTP libraries take care of this for you automatically but if
    you are writing a low-level hook this is important to remember.
-   GitLab ignores the HTTP status code returned by your endpoint.

## Secret Token

If you specify a secret token, it will be sent with the hook request in the `X-Gitlab-Token` HTTP header. Your webhook endpoint can check that to verify that the request is legitimate.

## 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`

#### 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.
