<Note>
  To follow along with **Postman**, see [API testing using Postman](/knowledge-base/testing/postman) for importing the Server API from OpenAPI and setting `baseUrl`, `secretKey`, and `userId`.

  This walk-through uses these **Server API** endpoints:

  * [Enroll verified authenticator](/api-reference/server-api/enroll-verified-authenticator) — `POST /users/{userId}/authenticators`
  * [Track action](/api-reference/server-api/track-action) — `POST /users/{userId}/actions/{action}`
  * [Validate action](/api-reference/server-api/validate-action) — `POST /validate`
  * [Get action](/api-reference/server-api/get-action) — `GET /users/{userId}/actions/{action}/{idempotencyKey}`
</Note>
