Random UUID
Value
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.

| 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.
