Hook rules

And

And rule will evaluate to true, if and only if all of the sub rules evaluate to true.

{
"and":
  [
    {
      "match":
      {
        "type": "value",
        "value": "refs/heads/master",
        "parameter":
        {
          "source": "payload",
          "name": "ref"
        }
      }
    },
    {
      "match":
      {
        "type": "regex",
        "regex": ".*",
        "parameter":
        {
          "source": "payload",
          "name": "repository.owner.name"
        }
      }
    }
  ]
}

Or

Or rule will evaluate to true, if any of the sub rules evaluate to true.

{
"or":
  [
    {
      "match":
      {
        "type": "value",
        "value": "refs/heads/master",
        "parameter":
        {
          "source": "payload",
          "name": "ref"
        }
      }
    },
    {
      "match":
      {
        "type": "value",
        "value": "refs/heads/development",
        "parameter":
        {
          "source": "payload",
          "name": "ref"
        }
      }
    }
  ]
}

Not

Not rule will evaluate to true, if and only if the sub rule evaluates to false.

{
"not":
  {
    "match":
    {
      "type": "value",
      "value": "refs/heads/development",
      "parameter":
      {
        "source": "payload",
        "name": "ref"
      }
    }
  }
}

Multi-level

{
    "and": [
    {
        "match": {
            "parameter": {
                "source": "header",
                "name": "X-Hub-Signature"
            },
            "type": "payload-hash-sha1",
            "secret": "mysecret"
        }
    },
    {
        "or": [
        {
            "match":
            {
                "parameter":
                {
                    "source": "payload",
                    "name": "ref"
                },
                "type": "value",
                "value": "refs/heads/master"
            }
        },
        {
            "match":
            {
                "parameter":
                {
                    "source": "header",
                    "name": "X-GitHub-Event"
                },
                "type": "value",
                "value": "ping"
            }
        }
        ]
    }
    ]
}

Match

Match rule will evaluate to true, if and only if the referenced value in the parameter field satisfies the type-specific rule.

Please note: Due to technical reasons, number and boolean values in the match rule must be wrapped around with a pair of quotes.

There are three different match rules:

1. Match value

{
  "match":
  {
    "type": "value",
    "value": "refs/heads/development",
    "parameter":
    {
      "source": "payload",
      "name": "ref"
    }
  }
}

2. Match regex

For the regex syntax, check out http://golang.org/pkg/regexp/syntax/

{
  "match":
  {
    "type": "regex",
    "regex": ".*",
    "parameter":
    {
      "source": "payload",
      "name": "ref"
    }
  }
}

3. Match payload-hash-sha1

{
  "match":
  {
    "type": "payload-hash-sha1",
    "secret": "yoursecret",
    "parameter":
    {
      "source": "header",
      "name": "X-Hub-Signature"
    }
  }
}

4. Match Whitelisted IP range

The IP can be IPv4- or IPv6-formatted, using CIDR notation. To match a single IP address only, use /32.

{
  "match":
  {
    "type": "ip-whitelist",
    "ip-range": "192.168.0.1/24"
  }
}
