If I already signed into my IdP, will I be logged in to Air automatically?

You can start SAML sign-in from https://app.air.inc/saml-sso-login or use the URL https://api.air.inc/integrations/saml/login/{ORGANIZATION-WORKSPACE-ID} . The URL that includes your organization's workspace ID, sends you directly to your identity provider and does not require entering your email beyond your initial login.
