Built-in nodes

Config, ports and output of httprequest, transform, log, conditional, switch, wait and wait_until

Every built-in action has the input port main. A node's output is what later nodes read as {{.node_results.<node_id>...}}, and config strings are templates.

When a node has an error port and fails, the failure goes through it with the reason in error. With nothing connected to error, the execution fails.

httprequest

Calls an HTTP endpoint. It can reach any address the server can, so limit outbound traffic where you run Operion.

{
  "id": "notify",
  "name": "Notify Slack",
  "type": "httprequest",
  "category": "action",
  "config": {
    "url": "https://hooks.slack.com/services/T000/B000/XXXX",
    "method": "POST",
    "body": "{\"text\": \"Welcome, {{.node_results.trigger.body.name}}\"}"
  }
}

Config	Description
`url`	Required
`method`	`GET` (default), `POST`, `PUT`, `PATCH`, `DELETE`, `HEAD` or `OPTIONS`
`headers`	An object of header names and values
`body`	The request body. When it is set and `headers` has no `Content-Type`, the request is sent as `application/json`
`timeout`	Seconds, from 1 to 300. Defaults to 30

Ports: success and error.

success sends on status_code, headers, body (the response as text) and json (the response parsed, when it is JSON). A network error, a timeout or a status of 400 or more goes to error.

transform

Builds a value from a template.

{"id": "greet", "name": "greet", "type": "transform", "category": "action", "config": {"expression": "{\"full_name\": \"{{.node_results.trigger.body.first}} {{.node_results.trigger.body.last}}\"}"}}

Config	Description
`expression`	Required. A template

Ports: success and error. success sends on {"result": <value>}, where the value is an object, a list, a number, a boolean or a string, as described in what a template returns.

log

Writes a line to Operion's log.

{"id": "done", "name": "done", "type": "log", "category": "action", "config": {"message": "order {{.node_results.trigger.body.order_id}} handled", "level": "info"}}

Config	Description
`message`	Required. A template
`level`	`debug`, `info` (default), `warn` or `error`

Ports: success and error. success sends on message, level and logged.

Config	Description
`condition`	Required. A template

The rendered value is true when it is true, a non-zero number, a non-empty list or object, or a non-empty string other than false, 0 and the other spellings of false. Anything else takes false. Both ports send on condition_result and evaluated_value.

switch

Takes the path named after a value.

{
  "id": "route",
  "name": "Route by plan",
  "type": "switch",
  "category": "action",
  "config": {
    "value": "{{.node_results.trigger.body.plan}}",
    "cases": [
      {"value": "basic", "output_port": "basic"},
      {"value": "premium", "output_port": "premium"}
    ]
  }
}

Config	Description
`value`	Required. A template
`cases`	A list of `{"value", "output_port"}`. A case matches when the rendered value, as text, equals its `value`

Ports: one per case output_port, default when no case matches, and error. Connect them as route:premium or route:default. The node sends on matched_value and output_port.

wait

Holds its branch for a duration.

{"id": "cool_off", "name": "Wait three days", "type": "wait", "category": "action", "config": {"duration": "72h"}}

Config	Description
`duration`	Required. A positive Go duration such as `30m` or `72h`

Port: success, which sends on the data the node received, or the body of an early resume.

wait_until

Holds its branch until a time.

{"id": "on_start", "name": "Wait for the first day", "type": "wait_until", "category": "action", "config": {"until": "{{.node_results.trigger.payload.start_date}}"}}

Config	Description
`until`	Required. A template that renders an RFC 3339 time, such as `2026-11-03T09:00:00-03:00`

Port: success, like wait. A time in the past continues right away. When until does not render a valid time, the execution fails.
