poq7r (poq7r) asked a question.
During self-service registration, is it possible to validate an attribute against an external directory prior to user creation with, for example, API?
An example would be user enters employee ID during sign up flow, check if employee ID exists in some database, returns valid, allows user creation to continue.
Not sure where to categorize this.
Note: This is for OIE

Unfortunately, I wasn't able to find information about how to achieve your inquiry but I would assume that this could be achieved through a custom implementation by using a custom page:
Additionally, my advice would be to leverage the Okta Developer forums for this type of questions and take advantage of their expertise.
