admins

POST /api/admin/admins (admins.create, step-up):
{mode:"invite", email, name, role, linkedCustomerSub?} new staff login; Cognito emails a temporary password
{mode:"promote", email, role, name?} link exactly one customer with that verified email
201 {admin, emailed}. Audited in admins.ts (admin.invite / admin.promote).

Caller and authorization

Staff cookie session; permission admins.create; fresh password + TOTP step-up (10 minutes). Write requests need same-origin JSON and X-Admin-CSRF from this session.

This is the private staff console on https://admin.handwrites.io. A personal API key, organisation token, student login or isolated app-testing credential does not authenticate this route.

Request contract

Location	Name	Required	Meaning
header	`X-Admin-CSRF`	Yes	Session-bound token from the staff page; not a developer credential.

The following is the accepted request shape, expressed as JSON Schema. It is not a runnable example. Runtime refinements and operation rules also apply.

Response and failures

Success: 201. POST /api/admin/admins (admins.create, step-up):
{mode:"invite", email, name, role, linkedCustomerSub?} new staff login; Cognito emails a temporary password
{mode:"promote", email, role, name?} link exactly one customer with that verified email
201 {admin, emailed}. Audited in admins.ts (admin.invite / admin.promote).

The wrapper returns {error:{code,message}} for CloudError failures, attaches Request-Id, and disables caching. Handle 401 by signing in; show role refusal for 403 forbidden, reauthenticate only for step_up_required, and collect a reason for 400 reason_required. A CSRF failure needs a current page/session token, not blind retries. Operation-specific 404/409/413/422/502/503 errors retain their status. Honor Retry-After on 429.

Implementation contract

Source snapshot: admin/src/app/api/admin/admins/route.ts. This reference describes the current working tree, not proof of deployment. The response service types and validators remain authoritative. The exact exported handler below makes conditional behavior reviewable. For helpers such as customer-routes or cloudRoute, see the shared API specification notes and the named service module.

/**

 * 201 {admin, emailed}. Audited in admins.ts (admin.invite / admin.promote).

export const POST = adminRoute("admins.create", async (request, ctx) => {
  const input = await readBody(request, body);
  const result = input.mode === "invite" ? await inviteAdmin(ctx, input) : await promoteCustomer(ctx, input);
  return adminJson(result, { status: 201 });

Do not use production customer data to test this operation. Use an authorized staff test account and a disposable target in an appropriate environment; email, deletion, role and credential mutations have real effects.
