Hi @lvilasboas-dti,

Apologies for the delay here - I just heard back from the team. Regarding custom headers/query parameters on server-side requests:

- **custom headers** : they are ignored
- **custom query params** : they ignored for `/token` endpoint. They can be used on `/authorize` and then can be incorporated into New Universal Llgin templates if they include `ext-` prefix. Read [this](https://auth0.com/docs/customize/login-pages/universal-login/customize-templates#custom-query-parameters). Available in postLogin event.request.query for calls to `/authorize`
- **custom body params** : they are available in postLogin and M2M `event.request.body` in Actions

Thanks,

Mary Beth
