# Get OpenID Configuration

> Get the OpenID configuration for a project.

Get the OpenID configuration for a project. The configuration can be used to determine the endpoints and settings for the Connected App's OpenID flow. This endpoint uses your [Custom Domain](/connected-apps/resources/custom-domains).

No authorization is needed for this endpoint.

This endpoint implements the [OpenID configuration](https://openid.net/specs/openid-connect-discovery-1%5F0.html#ProviderConfigurationRequest) endpoint.

<Info>
  We recommend using the [Custom Domain](/connected-apps/resources/custom-domains) whenever possible. For backwards compatibility reasons, this endpoint is also available at [https://test.stytch.com/v1/public/\$\{projectId}/.well-known/openid-configuration](https://test.stytch.com/v1/public/\$\{projectId}/.well-known/openid-configuration).

  * If your project uses a custom domain (CNAME) for API requests, this will be your custom domain (e.g., [https://login.yourcompany.com](https://login.yourcompany.com)), which is fully OIDC compliant.
  * If you do not use a custom domain, the issuer will be stytch.com/\$project\_id, which is not fully OIDC compliant and may not be accepted by all OIDC clients.

  To ensure OIDC compliance, set up and use a custom domain for your authentication flows. See the [Custom Domains guide](/connected-apps/resources/custom-domains) for more information.
