We are trying to implement single log out for SSO connections where auth0 is the service provider. In the application settings, I am able to set a back channel logout URI that is enabled for IdP-logout.

 ![Screenshot 2025-04-04 at 18.21.59](https://global.discourse-cdn.com/auth0/original/3X/1/b/1b10d0d35d8ee633605e7a629ff3c78de2158a3a.png)

I want to be able to test this configuration to ensure it’s working properly but I’m not sure how. How can I trigger this callback to be hit from an external IdP?

Thanks in advance,

Nadia

Hi @nadia.zyborska,

Thanks for your question.

You can test this functionality for OIDC back-channel logout by going to it’s endpoint: [`https://{yourDomain}/oidc/logout?id_token_hint={yourIdToken}&post_logout_redirect_uri={yourCallbackUrl}`](https://auth0.com/docs/api/authentication/logout/oidc-logout)

I recommend reviewing our [https://auth0.com/docs/authenticate/login/logout/back-channel-logout/configure-back-channel-logout](https://auth0.com/docs/authenticate/login/logout/back-channel-logout/configure-back-channel-logout) documentation.

Let me know if you have any follow-up questions.

Thanks,  
Rueben
