I want to use third party account authentication such as Auth0 and I was wondering if this was possible using their API? If so can you please help me? I am building an educational video subscription site for therapists and as the client base could be large with a bit of revenue I really want to make sure its secure. What SSO or SAML capabilities are there if any? Thank you so much for your time.
Have a look at the Wix Code API here and you will see how it is possible to do third party authentication through Wix Code.

How about as users buy a membership will the registration be able to write to a 3rd party ldap?
