Authentication with the Box API uses an Access Token to identify a user. The way in which an Access Token is acquired depends on the method used to authorize a user. The type of authorization available to an application depends on the use-case as well as the type of application that has been created in the developer console.
|Box Application Type||Authentication methods|
|Custom App||OAuth 2.0, JWT, or Client Credentials Grant|
|Limited Access App||App token|
|Custom Skill||No authentication method selection needed|
