We want to establish a federation from Auth0 to Criipto using an Enterprise OIDC connection. The IdP requires signed requests for the authorization endpoint call as defined in the [OIDC spec](https://openid.net/specs/openid-connect-core-1_0.html#RequestObject). Is there a way to configure the Enterprise OIDC connection via the Auth0 dashboard (or Management API) that it sends the parameters in a signed JWT token instead of request parameters as required by the OIDC spec? If not, any other ideas how to establish this federation?

Hi @elster,

Thanks for your question.

You could use a [post-login action script](https://auth0.com/docs/customize/actions/explore-triggers/signup-and-login-triggers/login-trigger) to append the query parameters as a custom claim in the JWT token. You could call the `event.request.query` property to get the query parameters that were passed in the login request.

I recommend checking out our [Adding custom claims to tokens](https://community.auth0.com/t/adding-custom-claims-to-tokens/84590) knowledge solution on how to accomplish this.

Let me know if you have any other questions.

Best,  
Rueben
