I have a shared folder. That link let me browse the file by ID - https://c2c.app.box.com/v/{folder}/file/{file_id}

Is it possible to get a direct link for the file downloading instead of browsing?

Hi , I think this might work for you:

Use this API to get the item for a shared link:

https://developer.box.com/reference/get-shared-items

This should return a folder object with the first X items in the folder.

I'm not getting any items from that folder when call get-shared-items:

Even if I call get-folders-id I'm not getting any share link for the files:

"item_collection": {
    "total_count": 6,
    "entries": [
      {
        "type": "file",
        "id": {id},
        "file_version": {
          "type": "file_version",
          "id": {id},
          "sha1": {sha1}
        },
        "sequence_id": "0",
        "etag": "0",
        "sha1": {sha1},
        "name": "File name"
      },

my bad, I missed a step.

Step 1: convert a shared link to an item (file or folder)
```
curl -X GET https://api.box.com/2.0/shared_items \
     -H 'Authorization: Bearer '
     -H "BoxApi: shared_link=https://c2c.app.box.com/s/v2vpg8ct70..."
```
In your case, this will return a folder object with an ID.
```
{
  "type": "folder",
  "id": "12345",
  "sequence_id": "0",
  ....
}
```
Step 2: Use the folder ID to list the items in the folder
```
curl -X GET https://api.box.com/2.0/folders/12345/items \
     -H 'Authorization: Bearer '
     -H "BoxApi: shared_link=https://c2c.app.box.com/s/v2vpg8ct70..."
```
Note that we use the same BoxApi header here as we did in the previous API.

This will return the same folder object but with a list of items in the item_collection attribute.

Step 3: Keep traversing the tree

You can keep traversing the tree here for every item in the folder. So in your case, if you want to access a file with file ID 23456, you'd use:
```
curl -X GET https://api.box.com/2.0/files/23456 \
     -H 'Authorization: Bearer '
     -H "BoxApi: shared_link=https://c2c.app.box.com/s/v2vpg8ct70..."
```
Step 4: Download the file

Finally, to download the file, simply call the endpoint to download the content.
```
curl -X GET https://api.box.com/2.0/files/23456/content \
     -H 'Authorization: Bearer '
     -H "BoxApi: shared_link=https://c2c.app.box.com/s/v2vpg8ct70..."
```
