# Webhooks

Webhooks are user-defined HTTP callbacks. They are triggered by database model (an object representing a table of data) lifecycle events (created, updated, saved and deleted).

Webhooks can be defined in Admin > General > Webhooks.

# Expressions

Expressions can be used in the condition, the URL and the request body.

# Attributes

Database model attribute names can be determined by inspecting the database schema (table column names) and model definitions.

  • Attributes can be embedded in an expression using two pairs of curly brackets ({{}}).
  • Attributes can change their value during an event. The previous value is accessible by appending _original to the attribute name.
  • Subattributes can be accessed with the . operator.

Examples: {{ id }}, {{ user.name }}, {{ thread.board.name }} and {{ thread.board_original.name }}.

# Filters

Filters can be applied to an expression using the pipe operator (|). Some filters have arguments that can be passed within parentheses (). Examples: {{ name | upper }}, {{ name | lower | capitalize }} and {{ name | truncate(5) }}.

The following filters are available:

  • truncate
  • lower
  • upper
  • capitalize.

# Condition

The condition is a series of boolean and relational expressions that are evaluated to determine whether to trigger the webhook. In addition to the expressions above, the condition supports expressions with the following operators:

  • relational operators equals == and NOT equals !=
  • logical operators AND && and || OR.

TIP

The logical AND operator takes precedence. That is, AND expressions are evaluated before OR expressions.

# Examples

# Send new forum posts to Discord

  • Model: ForumPost
  • Event: Created
  • Condition: {{ thread.bid }} == 1 (only include posts from the board with the ID 1)
  • URL: obtain from Discord Server Settings
  • Body:
{
	"embeds": [
		{
			"title": "{{ thread.topic }}",
			"url": "https://example.com/forums/posts/{{ pid }}",
			"description": "{{ content | truncate(150) }}",
			"footer": {
				"text": "Posted by {{ user.name }}",
				"icon_url": "{{ user.avatar }}"
			}
		}
	]
}
