Go Requires Chilkat v11.5.0+

Box: Refresh and Save Rotated OAuth Tokens

See more Box Examples

Refresh the user token saved by the authorization example. Box refresh tokens are single-use and expire after 60 days. Serialize refreshes for a token pair and save the replacement immediately; do not run concurrent refresh jobs.

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