Join a suggested organization
POST /fapi/v1/me/organization-suggestions/{domain_id}:join · called from the environment's sign-in host
Accepts a suggestion from List my organization suggestions: the authenticated user becomes a member of the suggested organization with the environment's default member role. The membership's source is domain_capture and the user is recorded as the actor; an organization_membership.created event is sent. Of two simultaneous joins, only one succeeds. Joining does not require a recently verified session: it grants only the default member role, and only for a domain whose address the user has verified. Requires the authenticated user's __Host-idp_session cookie; if the cookie is missing, expired, or revoked, returns 401 unauthenticated. A first-party app on another origin can instead send its front API access token (Authorization: DPoP <token> with a DPoP proof; see Front API access token).
With @keenauth/js: await keenauth.organizations.joinSuggestion(id).
