API to get a list of all the error pages

Is there an API through which I can get a list of all the error pages in OKTA? I need to customize the error pages.

Hi there. Unfortunately we do not have an API for this functionality. Are you using a custom URL? You should be able to customize the error pages pretty easily if so. See here:
