I have developed a module in drupal 7 for integrating Box different API. The following feature, i have integrated with this module.
1. JWT access token method for fetching data. Implement JWT zend framework library in Drupal module.
2. Fetching folder with all files details and metadata details using search query.
3. Creating/updating files in Box , using API call.
4. Creating/Updating metadata of files using API call.
5. Download files using API call.

Could we view the module files to take a look at what you have come up with?
