Errors

The Box APIs uses HTTP status codes to communicate if a request has been successfully processed or not.

Most client errors in the HTTP 4XX, and some server errors in the HTTP 5XX range returns a standard client error JSON object.

Error	`invalid_grant`
Message	Current date time must be before the expiration date time listed in the 'exp' claim.
