The SAML Auth provider configuration interface. A SAML provider can be created via createProviderConfig().



Optional callbackURL

callbackURL: string

This is fixed and must always be the same as the OAuth redirect URL provisioned by Firebase Auth, unless a custom authDomain is used. The callback URL should also be provided to the SAML IdP during configuration.


displayName: string

The user-friendly display name to the current configuration. This name is also used as the provider label in the Cloud Console.


enabled: boolean

Whether the provider configuration is enabled or disabled. A user cannot sign in using a disabled provider.


idpEntityId: string

The SAML IdP entity identifier.


providerId: string

The provider ID defined by the developer. For a SAML provider, this is always prefixed by saml.. For an OIDC provider, this is always prefixed by oidc..


rpEntityId: string

The SAML relying party (service provider) entity ID. This is defined by the developer but needs to be provided to the SAML IdP.


ssoURL: string

The SAML IdP SSO URL. This must be a valid URL.


x509Certificates: string[]

The list of SAML IdP X.509 certificates issued by CA for this provider. Multiple certificates are accepted to prevent outages during IdP key rotation (for example ADFS rotates every 10 days). When the Auth server receives a SAML response, it will match the SAML response with the certificate on record. Otherwise the response is rejected. Developers are expected to manage the certificate updates as keys are rotated.
