    Change Folder Owner

    Change Folder Owner

    To change the owner of a folder, first invite the user you wish to transfer the folder to as a collaborator on the folder.

    cURL
    curl -i -X POST "https://api.box.com/2.0/collaborations" \
         -H "authorization: Bearer <ACCESS_TOKEN>" \
         -H "content-type: application/json" \
         -d '{
           "item": {
             "type": "file",
             "id": "11446498"
           },
           "accessible_by": {
             "type": "user",
             "login": "user@example.com"
           },
           "role": "editor"
         }'

    Then, update the created collaboration by changing the role of that invited user to owner.

    cURL
    curl -X PUT https://api.box.com/2.0/collaborations/1234 \
        -H "authorization: Bearer <ACCESS_TOKEN>" \
        -H "content-type: application/json" \
        -d '{
          "role": "owner"
        }'
    

    Depending on the settings, a user with access to a folder might be able to invite other users, yet in all cases only the current owner of a folder can transfer the ownership.
