Ok, so no way to get to single\_sign\_on\_record then?

Am I understading [the code you referred to](https://github.com/discourse/discourse_api/blob/master/lib/discourse_api/api/sso.rb#L14-L16) correctly, in that I should supply a field named “custom\_external\_id” with my SSO - then it will save to the custom field “custom\_external\_id” (it has to be prefixed “custom”), right?

Is there an easier way to traverse all users and set the new custom field, other than to write a script that calls sync\_sso on the thousands of users? It seems a lot of work to get to a field we already have in the system 🙂
