Incoming Bitbucket webhook

Bitbucket does not pass any secrets back to the webhook. Per their documentation, in order to verify that the webhook came from Bitbucket you must whitelist the IP range 104.192.143.0/24:

[
  {
    "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 Values in the request body can be accessed in the command or to the match rule by referencing 'payload' as the source:

    "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

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

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

#!/bin/bash
curl -H "Content-Type:application/json" -X POST -d @testRequest.json \

or in a single line, using https://github.com/jpmens/jo to generate the JSON code

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 In order to leverage the Signing Key for addtional authentication/security you must configure the trigger rule with a match type of "scalr-signature".
