REST Message nodes

A REST Message is a reusable outbound HTTP call — method, URL, headers, body template, auth — defined once in WP-PFManagement and given a key. In a workflow you drop the Invoke REST message node (in the Connections group), point it at the key, and wire its inputs.

How it runs

At execution the node resolves the definition for its key from Management, fills the template from its input pins, and issues the call through Workflow's single outbound HTTP stack — the same one every built-in HTTP node uses:

retry on 429/5xx honouring Retry-After,
SSRF protection (private / link-local / metadata addresses are refused before any request leaves the server),
redacted logging (secrets never hit the timeline in the clear).

The parsed response is emitted as output pins for downstream nodes.

Why define it in Management

The endpoint and its credentials live in one record, reused by every workflow that calls it. Rotate a key or change a base URL once and every automation follows — no editing each workflow.
