The Unique ID Generator action generates a server-side unique identifier for every successful Bricks Form submission and writes it into a specified form field. You can optionally prepend a custom prefix.
This is ideal for tracking submissions, creating opaque references, or correlating entries across external systems.
Settings
After adding a Form element in Bricks, open Actions and select Unique ID Generator. A dedicated Unique ID Generator group appears with the following controls:
Field To Update
Purpose: Select the form field that will receive the generated ID.
Requirement: Must be set; otherwise, the action does nothing.
Recommendation: Use a Hidden field to avoid exposing the value to end users.
Prefix
Type: Text
Dynamic data: Supported (the value is rendered before sanitization).
Behavior: Optional string prepended to the generated ID, followed by a hyphen.
Compatibility with Other Features
Other Bricks Form actions: Because the ID is stored in a form field, subsequent actions (Email, Webhook, etc.) can reference it.
