Random UUID

Description

Pure function returning a freshly generated UUID as a string.

When to use

Use Random UUID whenever you need a unique identifier — for example, as a correlation ID for an outgoing HTTP request, a unique key for a batch job, or a nonce for a security-sensitive operation. The node has no inputs and generates a new UUID every time its output is evaluated. Wire the string output directly into any node that expects a string identifier.

Pin Type Notes
Value string A randomly generated UUID in standard 8-4-4-4-12 lowercase hex format.

Example

Attach a correlation ID to every outgoing HTTP request for tracing. Wire the Value output of Random UUID into the Text 2 input of Concatenate strings (Text 1 set to "X-Correlation-ID: ") to build the header value string. Include the Result output in the HTTP request so downstream services can correlate log entries.
