# Certificates

The Single Sign-On APIs allow you to manage your SAML 2.0 SSO configurations. You can also work with your SSO integrations using the [SSO section of the Twilio SendGrid App](https://app.sendgrid.com/settings/sso).

The Certificates API allows you to create, modify, and delete SSO certificates. A SAML certificate allows your IdP and Twilio SendGrid to verify requests are coming from one another using the `public_certificate` and `integration_id` parameters.

For more information about managing SSO Certificates, see the [Twilio SendGrid SSO documentation](/docs/sendgrid/ui/account-and-settings/sso/).
