system/response — Sends a structured HTTP reply (body, status, headers) back to the caller. Use as the final step of an API-triggered workflow.

Where it appears

The HTTP Response block lives in the Logic & control group of the Workflow Builder.

Field	Type	Required	Default	Description
`data`	code	Yes	—	JSON response body. Use <nodeId:Label.field> to inject values from previous nodes.
`status`	text	No	`200`	HTTP status code (default: 200)
`headers`	code	No	—	Additional HTTP headers to include in the response

Inputs are the configurable fields above. The block produces these outputs:

Outputs

Reference an output downstream with <HTTP Response.field>.

Name	Type	Description
`data`	json	Response body
`status`	number	HTTP status code
`headers`	json	Response headers
`success`	boolean	Whether the response was formatted successfully
`error`	string	Error message if formatting failed

A minimal configuration for this block:

{
  "type": "system/response",
  "config": {
    "data": "...",
    "status": "200"
  }
}

Required field (data) must be set, or the block fails validation before it runs.
On failure the error output is populated; downstream blocks that reference other outputs may not receive values.
