        }
      ]
    }
  }

## Incoming Bitbucket webhook

Bitbucket does not pass any secrets back to the webhook.  [Per their documentation](https://confluence.atlassian.com/bitbucket/manage-webhooks-735643732.html#Managewebhooks-trigger_webhookTriggeringwebhooks), in order to verify that the webhook came from Bitbucket you must whitelist the IP range `104.192.143.0/24`:

```json
[
  {
    "id": "webhook",
    "execute-command": "/home/adnan/redeploy-go-webhook.sh",
    "command-working-directory": "/home/adnan/go",
    "pass-arguments-to-command":
    [
      {
        "source": "payload",
        "name": "actor.username"
      }
    ],
    "trigger-rule":
    {
      "match":
      {
        "type": "ip-whitelist",
        "ip-range": "104.192.143.0/24"
      }
    }
  }
]
```

## Incoming Gitlab Webhook
Gitlab provides webhooks for many kinds of events. 
Refer to this URL for example request body content: [gitlab-ce/integrations/webhooks](https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/user/project/integrations/webhooks.md)
Values in the request body can be accessed in the command or to the match rule by referencing 'payload' as the source:
```json
[
  {
    "id": "redeploy-webhook",
    "execute-command": "/home/adnan/redeploy-go-webhook.sh",
    "command-working-directory": "/home/adnan/go",
    "pass-arguments-to-command":
    [
      {
        "source": "payload",
        "name": "user_name"
      }
    ],
    "response-message": "Executing redeploy script",
    "trigger-rule":
    {
      "match":
      {
        "type": "value",
        "value": "<YOUR-GENERATED-TOKEN>",
        "parameter":
        {
          "source": "header",
          "name": "X-Gitlab-Token"
        }
      }
    }
  }

## A simple webhook with a secret key in GET query

__Not recommended in production due to low security__

`example.com:9000/hooks/simple-one` - won't work  
`example.com:9000/hooks/simple-one?token=42` - will work

```json
[
  {
    "id": "simple-one",
    "execute-command": "/path/to/command.sh",
    "response-message": "Executing simple webhook...",
    "trigger-rule":
    {
      "match":
      {
        "type": "value",
        "value": "42",
        "parameter":
        {
          "source": "url",

use then the curl tool to execute a request to the webhook.

<pre>
#!/bin/bash
curl -H "Content-Type:application/json" -X POST -d @testRequest.json \
http://localhost:9000/hooks/test-file-webhook
</pre>

or in a single line, using https://github.com/jpmens/jo to generate the JSON code
<pre>
jo binary=%filename.zip | curl -H "Content-Type:application/json" -X POST -d @- \

## Incoming Scalr Webhook
[Guide by @hassanbabaie]
Scalr makes webhook calls based on an event to a configured webhook endpoint (for example Host Down, Host Up). Webhook endpoints are URLs where Scalr will deliver Webhook notifications.  
Scalr assigns a unique signing key for every configured webhook endpoint.
Refer to this URL for information on how to setup the webhook call on the Scalr side: [Scalr Wiki Webhooks](https://scalr-wiki.atlassian.net/wiki/spaces/docs/pages/6193173/Webhooks)
In order to leverage the Signing Key for addtional authentication/security you must configure the trigger rule with a match type of "scalr-signature".

```json
[
    {
        "id": "redeploy-webhook",
        "execute-command": "/home/adnan/redeploy-go-webhook.sh",
        "command-working-directory": "/home/adnan/go",
        "include-command-output-in-response": true,
        "trigger-rule": 
		{
            "match": 
			{
                "type": "scalr-signature",
                "secret": "Scalr-provided signing key"
            }
        },
        "pass-environment-to-command": 
		[
            {
                "envname": "EVENT_NAME",
                "source": "payload",
                "name": "eventName"
            },
            {
                "envname": "SERVER_HOSTNAME",
                "source": "payload",
                "name": "data.SCALR_SERVER_HOSTNAME"
            }
        ]
    }
]

```

## Travis CI webhook
Travis sends webhooks as `payload=<JSON_STRING>`, so the payload needs to be parsed as JSON. Here is an example to run on successful builds of the master branch.

```json
[
  {
    "id": "deploy",
    "execute-command": "/root/my-server/deployment.sh",
    "command-working-directory": "/root/my-server",
    "parse-parameters-as-json": [
      {
        "source": "payload",
        "name": "payload"
      }
    ],
    "trigger-rule":
    {
      "and":
      [
        {
          "match":
          {
            "type": "value",
            "value": "passed",
            "parameter": {
              "name": "payload.state",
              "source": "payload"
            }
          }
        },
        {
          "match":
          {
            "type": "value",
            "value": "master",
            "parameter": {
              "name": "payload.branch",
              "source": "payload"
            }
          }
        }
      ]
    }
  }
]
```
