Check whether a session is signed in and run scripted sign-in logic when it is not.
librettoAuthenticate()
librettoAuthenticate is the runtime helper for workflows that combine an auth profile with scripted sign-in logic.
Options
Checks whether the current browser page is already signed in. Return
true
only when the workflow can safely continue.signIn
(ctx: LibrettoWorkflowContext, credentials: Record<string, string>) => Promise<void> | void
required
Performs the sign-in flow when
isSignedIn returns false.Credential values to pass to
signIn. In workflows, pass
input.credentials from declared workflow credentials.Optional environment variable prefix used only when
credentials is omitted.
Workflow code should normally pass input.credentials instead.Return value
true when the initial isSignedIn check passed, meaning the saved profile
was already signed in. false when Libretto ran the signIn step.Example
signIn runs, librettoAuthenticate calls isSignedIn again. If the session is still not signed in, it throws an error instead of letting the workflow continue in a logged-out state.
Pair
librettoAuthenticate with authProfile: { name, refresh: true } when
a successful sign-in should update the profile for future runs.
