These are the tasks that can be performed to manage the FastAPI repository by [team members](./fastapi-people.md#team){.internal-link target=_blank}.

/// tip

This section is useful only to a handful of people, team members with permissions to manage the repository. You can probably skip it. 😉

### Em produção

Em seu sistema de produção, você provavelmente tem um frontend criado com um framework moderno como React, Vue.js ou Angular.

  public void requestOauthSession(String scopes, String team) throws Exception {
    if (sessionFactory == null) {
      sessionFactory = new OAuthSessionFactory(slackApi);
      sessionFactory.start();

    HttpUrl authorizeUrl = sessionFactory.newAuthorizeUrl(scopes, team, session -> {
      initOauthSession(session);
      System.out.printf("session granted: %s\n", session);
