The Hosted Login, OAuth 2.0, and OpenID Connect APIs represent your primary toolset for managing Hosted Login. Most Hosted Login management tasks can only be carried out by using API calls. Keep in mind, too that some Hosted Login management tasks, such as managing two-factor authentication messages, or creating, modifying, and deleting Hosted Login links, require the use of other operations. For example, you need to use the Configuration API to manage two-factor authentication messages or Hosted Login Links.
Note that Hosted Login requires the use of token-based authentication: you must obtain an administrative access token before you can call most Hosted Login APIs. See the Hosted Login Get started page for more information.
