Box: Get a Service Account Token with Client Credentials

See more Box Examples

Obtain a Box service-account token using the client credentials grant. Configure and authorize a Server app first. Load credentials from protected application configuration; do not ship a client secret in a public client.

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