Accessing Query String Parameters in a Pre-User Registration Action

Knowledge Articles

Problem statement

For certain sign up flows, additional query string parameters need to be passed in order to handle the business logic related to a given user. This is possible in a Post-Login Action with ‘event.request.query’ but it appears the Pre-User Registration Action does not have access to this value.

Is it possible to access additional query string parameters sent during a sign up flow within the Pre-User Registration Action?

Solution

Currently accessing query string parameters in the Pre-User Registration Action is not supported.
