Hi @jmaddox
Welcome to the Auth0 Community. It’s great to have you here 
I’m not sure what you’re referring to regarding the json file but if you were using SAML you would need to ensure that your IdP is sending the data that you need in the SAML response, if so it’s just a case of mapping it into Auth0, I did a similar response here which may help you https://community.auth0.com/t/user-profiles-are-not-reflecting-the-current-saml-field-mappings/105914/3
Please let us know if you need anything further.
Warm regards.
