Markdown
processing.markdown Processing v0.1.0 Converts Markdown to HTML or HTML to Markdown.
Finding it in the library
Search the builder's node library for Markdown (it lives under Processing). A single click opens the in-editor docs panel shown here — description, ports, and every property, without leaving the canvas. Double-click (or drag) to add it to the workflow.
Wired up in the builder
Markdown in a real, runnable flow — captured live from the Studio editor, exactly as it looks on your canvas. This is the same workflow used for the example input & output below.
How it’s configured
The node’s Configure panel as it opens in the builder when you select the step — every setting laid out with real values. Click any field to edit it.
Ports
Ports are the node’s contract with its neighbours. In the editor a port label renders bold when wired and italic when optional; ◈ ports accept attachment carriers rather than data wires.
| Direction | Port | Label | What flows through it |
|---|---|---|---|
| Input | input | Input | |
| Output | output | Converted |
How data flows through it
Markdown consumes the content of the incoming envelope — when it is fed directly by a trigger, the trigger’s wrapper is unwrapped at the node boundary so the node sees the actual data, not the metadata shell. Its output becomes the payload for the next node, while the envelope (trace ids, correlation, binary refs) rides along untouched. In the Runs view you always see the whole envelope for both sides of this node.
Expressions in the config
None of this node’s properties are string-typed, so {{ }} expressions
don’t apply here — JSON- and code-typed fields are always taken literally.
Build it with AI
Every node in this reference is reachable through Flowdrome’s
AI Copilot and the
MCP tools — say what you want, and the graph surgery
happens server-side. Node types resolve fuzzily, so the catalog label
(Markdown) works as well as the exact type id (processing.markdown).
In the Copilot panel (or any connected AI):
add a markdown node after the trigger As a step in a create_chain_workflow call:
{"type":"Markdown","config":{}} Raw MCP call — add this node to a workflow with add_node
curl -s -X POST http://localhost:48170/mcp -H "content-type: application/json" -d '{ "jsonrpc": "2.0", "id": "1", "method": "tools/call", "params": { "name": "add_node", "arguments": { "workflowId": "<id>", "type": "Markdown" } } }' Example input & output
Captured from a real test run of the workflow above — this is what you see in the run data panel after pressing Test workflow.
Input — what the node received
body.Output — what the node produced
Property reference
Every setting, with its type and default — the same fields shown configured in the panel above.
| Property | Type | Default | Description |

Source fieldsourceField | field | "" | Dot-path to the text to convert. Blank = the whole input (when it's a string). |
Output fieldoutputField | field | "" | Where to write the result. Blank = replace the payload with the converted text. |
