The Registration Form trigger is listed in the WordPress User group in the AI Agent Workflows editor. It starts a workflow when WordPress fires the register_form hook. The exact timing follows that hook; not every user-related hook represents a completed account change.

When this trigger fires
This hook relates to displaying the registration form. It should not be treated as confirmation that a user account was created; use the separate User Register trigger for that event.
Event data and privacy
User-trigger payloads use source, event, and hook arguments under args. WordPress user objects are converted to basic fields such as ID, login, email, and display name, but other scalar arguments may remain in the payload. Inspect a sample before mapping values.
Configure the trigger
- Open the workflow in the visual editor and open the node picker.
- Select WordPress, then User, and add Registration Form.
- Inspect a captured sample to understand the hook arguments. This catalog entry has no user-specific filter field.
- Save and test only with controlled data. Avoid storing or forwarding credentials and other sensitive account information.
Source hook
