Summary
Wants to generate a pre-authenticated, single-use embed URL for a new app builder (React, /rr/app/) app so external users without Retool accounts can access embedded pages, but the classic POST /api/embed-url/external-user flow only lands on the classic /embedded/authed/ route (empty shell for React apps) and the /rr route always forces a login.
AI Response
This is a current limitation rather than a misconfiguration: the new app builder is still in beta, and public/external access — including pre-authenticated embed URLs and public/embedded link generation — is not yet supported for new-builder (React) apps. Retool staff have confirmed this directly and noted these capabilities are actively being worked on, while all embed and external-user tooling (including POST /api/embed-url/external-user) remains scoped to classic apps. For now, the only supported paths are to keep external-facing embeds on a classic app or to have users authenticate with a Retool session; there is no new-builder equivalent of the external-user embed endpoint yet. Following the linked threads is the best way to track when this ships.

Unable to Generate Public/Embedded Link for New App
Retool staff confirm that public/embedded link generation is not yet available in the new app builder beta and is actively being added, pointing to the tracking thread for updates.
A Retool staff reply directly states that public (no-account) access is not yet supported in the new app builder, corroborating why logged-out external users are bounced to login.
