Turning waitlist mode off does **not** do this, and the separation is deliberate — the people already in line would otherwise be left holding a password that never attached, and would find out at the login screen. Idempotent: an entry already admitted is skipped, so a second call mails nothing. ## OpenAPI ````yaml /api-reference/openapi.json post /v1/organization/waitlist/admit openapi: 3.1.0 info: title: UserKit API version: 1.0.0 description: >- The HTTP surface of UserKit. Two planes share one API. The **staff plane** is what a human uses in the panel: users, organizations, roles, members, keys. The **customer plane** is what a developer's own product uses: contacts, identities, hosted or federated sign-in. Every error answers the same envelope — `{"error": {"code", "message"}}`. The `code` is a stable contract to branch on; the `message` is for a person and may change. servers: - url: '{baseUrl}' description: The API host. variables: baseUrl: default: https://api.userkit.dev description: Base URL of the API, no trailing slash. security: - sessionToken: [] tags: - name: Authentication description: >- Public sign-up, sign-in, two-factor and password recovery for staff accounts. - name: Session description: >- The active session: who the caller is, which organization they are in, and signing out. - name: Account description: The caller's own account — profile, password, sessions, avatar. - name: Two-factor description: >- TOTP setup, activation and recovery codes. Returns 501 when two-factor is unavailable on the server. - name: Organizations description: The organizations a user belongs to, and the active one. - name: Environments description: >- The live and test environments seeded with every organization, and their identity settings. - name: Members description: Memberships and invitations. - name: Roles description: Roles and the permission catalogue they draw from. - name: Audit log description: >- What staff did inside an organization. Append-only, and read behind its own permission. - name: API keys description: Secret keys (`uk_sk_…`) and publishable keys (`uk_pk_…`). - name: Contacts (staff session) description: >- The staff view of the customer plane, opened by a staff session. Reads take `?environment=` as an explicit view parameter. - name: Contacts (API key) description: >- The machine surface, authenticated by an API key. The environment is the key's environment and cannot be named by the caller. - name: Customer plane description: >- Called from the developer's own pages with a publishable key: boot, magic link, and the contact's own session. - name: Hosted auth description: >- Sign-up, sign-in, verification and recovery for contacts, when UserKit owns the account. - name: Customer teams description: >- A customer is a team. Its roster, its invitations and its two roles — owner and member — administered by the contact's own session. The active customer travels in `X-Customer-Id`. - name: Webhooks description: >- Outbound webhooks: endpoints, the published event catalogue, the delivery log, replay and test sends. Never gated by a plan — webhooks are a developer primitive. - name: Catalogue description: >- The plans, prices and features **you** sell to your own customers. Per environment, a price per currency, and `recurring` or `one_time`. Distinct from the plan you are on with UserKit, which is `GET /v1/organization/entitlements`. - name: Subscriptions description: >- What one of **your** customers is paying you, mirrored from the gateway that charges them. The gateway is the truth about money — it holds the schedule, runs the retries and decides what a proration is worth — so these routes ask it to change something and answer with what it then said. `provider_synced_at` is how stale the copy admits to being. - name: Provider webhooks description: >- Where a payment provider delivers to. Not a surface you call — it is a URL you paste into the provider's dashboard, which is why it sits outside `/v1`: a version bump must never mean editing a setting in somebody else's product. Signed with the secret of the connection named in the path, and safe to retry. - name: Entitlements description: >- What one of **your** customers may do, resolved: the plan their subscription carries, plus the overrides you promised them on top. This is the read your own gate calls, so it is cached and answers in one round trip. It is a different question from `GET /v1/organization/entitlements`, which is the plan **you** are on with UserKit — two catalogues, same word, different money. paths: /v1/organization/waitlist/admit: post: tags: - Contacts (staff session) summary: Let people in description: >- Admission is the act that turns an entry into an account somebody can use: it attaches the password they parked at sign-up and mails them the link that proves their address and signs them in.
