Box: Authorize a User with OAuth 2.0

See more Box Examples

Interactive local-development example using a browser and a loopback callback. Register exactly http://localhost:3017/ in the Box User app. Run this in a trusted environment that can hold the client secret. A deployed web app must handle its registered HTTPS callback on the server.

See the Box API guide for setup and the complete workflow.
