Hello Experts,

we have a requirement to integrate box tool to servicenow, when we explored on developer.box.com we found the generic APIs for Upload file,Download file, Create Folder.....etc.

But we need end point for box to upload a document from servicenow to perform outbound activity from servicenow.

Please help on this......Thanks in advance
