Installation

Download

Download and copy this repository to /site/plugins/webhooks.

Git submodule

git submodule add https://github.com/errnesto/kirby-plugin-webhooks.git site/plugins/webhooks

Composer

composer require errnesto/kirby-plugin-webhooks

Setup

This plugin looks for webhook configurations in the kirby site object. So to create a webhook you could just edit the content/site.txt file:

Webhooks:

-
  url: >
    https://webhook.site/74a7ed53-7091-4871-a1d7-749417b24269
  payload: '{"secret":"123"}'
  triggers: page.create:after, page.update:after

The config must be stored under the key Webhooks as yaml array.
Every webhook needs the following options:

• url: The URL to post to when a kirby hook is triggered
• payload: The body of the post request
• triggers: A comma seperated list of kirby hooks

A blueprint to edit the webhooks in the panel could look like this:

webhooks:
  label: Webhooks
  type: structure
  fields:
    url:
      label: URL
      type: url
    payload:
      label: Payload
      type: text
    triggers:
      label: Triggers
      type: tags

Options

You can customize the requests the plugin sends with your own functions.
Every function gets the following parameters:

• $trigger: The name of the hook that caused the webhook to be called
• $webhook: The webhook read from the site object. (This will include any field you define)
• ...$params: All the params from the kirby hook.

You can set all of the following options by returning them in your /site/config/config.php:

getURL()

// default:
return [
  'errnesto.webhooks.getURL' => function ($trigger, $webhook, ...$params) {
    return $webhook['url'];
  }
];

getHeader()

return [
  // default:
  'errnesto.webhooks.getHeader' => function ($trigger, $webhook, ...$params) {
    return "Content-type: application/json\r\n";
  }
];

getMethod()

return [
  // default:
  'errnesto.webhooks.getMethod' => function ($trigger, $webhook, ...$params) {
    return "POST";
  }
];

getPayload()

return [
  // default
  'errnesto.webhooks.getPayload' => function ($trigger, $webhook, ...$params) {
    return $webhook['payload'];
  },
];

TODO

• Add custom panel view and store webhooks somewhere else?
• Returning null from getURL should skip a hook and not cause an error
• Option to make hook non blocking?
