> Use this file to discover all available pages before exploring further.

> ## Agent Instructions
> Use Stable documentation by default. Honor an explicit Beta request or a URL under /docs/beta/. If the requested version conflicts with the installed CLI package or API origin, clarify the target before writing integration code.
> Pages under /docs/beta/ document Beta; other product pages document Stable. Keep the CLI package, commands, API origin, and credentials within the selected version. State the documentation version in your answer.
> For MCP search, always pass version: Stable or version: Beta. Unfiltered search mixes both versions. For filesystem reads, keep Beta queries under /beta/ and exclude /beta/ from Stable queries; discover paths before reading them.
> The public docs base is https://photon.codes/docs. Convert MCP page paths to public URLs under that base, preserving /beta/ when present. Read https://photon.codes/docs/skill.md for version selection and https://photon.codes/docs/llms.txt for the version indexes.

# Begin organization SSO admission

> Begin organization SSO admission: beginOrganizationSsoAdmission in the TypeScript, Python and Rust clients.

`POST /v1/auth/organizations/{orgId}/sso/admission`

Returns an SSO admission URL for an existing account and the selected organization. Supply returnTo for the continuation URL. Admission requires completing the returned authentication flow; creating the URL does not itself grant membership.
