hi @Lija, Thanks for the response, I have passed the redirect_url as parameter in my request.
I have found the rootcaused. Just post here if anyone having same issue.
My application is running behind a load balancer, and https request was forwarded as http (s was removed). Once my application send verification request to okta, I get url mismatched error because ‘https:…’ != ‘http://…’
A work around to change http to https internally fixed my issue.
Thanks
