Hi, I’d like to embed the SSO `external_id` in some custom Javascript I’m pasting into my theme footer (using the ‘Custom HTML/CSS’ button)… is there a way to access the `external_id` from that template? i.e. something sorta like:

```plaintext
<script>
   var id = {{ sso.external_id }};
</script>

```

If I can’t embed `external_id`, I would love to be able to embed the `username` and `email`.

Hi,  
you could map `sso` field to custom user field and use it like this

```plaintext
const user = api.getCurrentUser()
console.log(user.custom_fields.external_id)

```

How to map sso field to custom user field, check here: [Setup DiscourseConnect - Official Single-Sign-On for Discourse (sso)](https://meta.discourse.org/t/official-single-sign-on-for-discourse-sso/13045)

You need to make that custom field public in the settings in order to access it in the theme.
