Request and Payload Transformations

Event triggers and cron triggers support request and payload transformations to reshape the outgoing webhook request. One-off scheduled events do not support transformations.

Request Options Transform

Override the default POST method (GET, PUT, PATCH, DELETE), customize the URL path with templates, and add query parameters.

• Method – choose GET, PUT, PATCH, or DELETE instead of the default POST
• URL path – use a template to append to the base URL: {{$base_url}}/custom-path
• Query parameters – add as key-value pairs or as a URL string template

Payload Transform

Transform Type	Editor	Description
application/json	Template editor	Kriti template with access to template variables
application/x-www-form-urlencoded	Key-value form editor	Form-encoded key-value pairs
Disabled	None	No body sent with the request

Note

The dashboard shows a live preview of the transformed request body.

Template Variables

Variable	Description
$body	Original request body (the full event payload)
$base_url	Webhook base URL
$session_variables	User session variables
$query_params	URL query parameters
$response.status	Response status code (for response transforms)

Example: Sending to Slack

{
  "text": "Row {{ $body.event.op }} in {{ $body.table.name }}: {{ $body.event.data.new }}"
}
