Which UUID version should I use?

Version 4 (random) is the most broadly compatible and is a safe default. Use other versions if the target system explicitly requires a specific version — for example, version 5 for deterministic, name-based UUIDs.

Can I use Sequence Generator to paginate through API results?

Yes. Configure the sequence to match your page range, then use each value as the page number in a loop that calls the API.

Does Sequence Generator persist its state between automation runs?

No. The generated sequence exists only within the current run. Store the last value in an external system if you need a counter that increments across runs.

The Identifiers & Sequences operations in the Utility node generate unique identifiers and ordered sequences inside an automation — UUID values in multiple versions and incrementing number sequences for keying records, ordering steps, or producing unique references without external dependencies.

Overview

Two lightweight generator operations. Generate UUID supports multiple UUID versions so you can match the version expected by the target system. Sequence Generator produces a numeric series, useful for batching, pagination, or assigning ordinal positions to a set of items.

Operations

Operation	What it does
Generate UUID of different versions	Generates a Universally Unique Identifier (UUID). Supports multiple UUID versions — select the version that matches the target system's requirements. Version 4 (random) is the most broadly compatible default.
Sequence Generator	Produces a numeric sequence defined by a start value, end value, and step. Use for pagination, batch indexing, or assigning ordered keys to a set of items.

Notes

Keep the following in mind when using these operations.

UUID versions differ in how the identifier is constructed — random, time-based, or name-based. Choose the version the receiving system expects. If in doubt, version 4 (random) is the most widely accepted.
For globally unique keys that must survive across systems and runs, prefer UUID over sequential integers from Sequence Generator.
Sequence Generator state is in-memory for the duration of the automation run; it does not persist between runs. If you need a persistent counter, store the value externally.
